Netafim
It all began in 1965, a year when the concept of precision irrigation was still a distant dream. Netafim, founded in that pivotal year, set out to revolutionize the way water was delivered to crops. Their innovation was the drip irrigation system – a paradigm shift that promised to change everything from crop yields to resource efficiency. By delivering water directly to the plant's root zone, the system minimized wastage and maximized the effectiveness of each drop. This innovation was not just about watering plants; it was about transforming agriculture itself.
Abed Masarwa, VP of Products at Netafim, encapsulates the essence of this revolution succinctly: “Precision irrigation is all about helping farmers achieve higher yields and better-quality crops, while using less water, fertilizer and energy.”
This philosophy is deeply embedded in every facet of Netafim’s approach, from engineering and project management to their cutting-edge digital farming solutions.
"Our innovative products are designed with the farmer’s needs in mind and offer outstanding value, durability, ease of installation and diversity, tailored to farming operations of any size," Masarwa adds.
Tailoring irrigation to crop and terrain
The success of precision irrigation lies in its adaptability. Unlike traditional irrigation methods that often lead to uneven water distribution and waste, drip irrigation systems can be meticulously designed to meet the specific needs of different crops.

Tailoring irrigation to crop and terrain
The success of precision irrigation lies in its adaptability. Unlike traditional irrigation methods that often lead to uneven water distribution and waste, drip irrigation systems can be meticulously designed to meet the specific needs of different crops.
“The most common layout of a drip irrigation system is typically designed around the specific needs of the crop being cultivated, notes Masarwa. “For row crops (e.g., corn, potatoes, soybeans), the system usually features driplines placed along the rows to ensure that water is delivered directly to the root zones of the plants.”
In contrast, for crops that are broadcast or widely spaced, the layout of the driplines changes. They may be arranged in a grid pattern or spaced out more widely to cover a larger area. This adaptability is crucial for optimizing irrigation performance and resource use, tailored specifically to the type of crop and its planting configuration.
Another significant advancement in drip irrigation technology is the development of various types of emitters, each designed to cater to different needs and conditions. The most common drippers used in drip irrigation systems include pressure-compensated and non-pressure-compensated types.
“The choice of dripper often depends on the specific requirements of the crop, the terrain slope and the irrigation conditions,” says Masarwa.
Netafim systems can be customized to accommodate different soil characteristics, such as sandy, loamy or
clay soils.

Pressure-compensated emitters are particularly valuable in greenhouses, orchards and uneven terrains. They maintain a consistent flow rate despite fluctuations in water pressure, ensuring uniform distribution. This is especially important in challenging topographies where water pressure might vary significantly.
On the other hand, non-pressure-compensated emitters are suitable for systems with stable pressure and flatter terrains. They provide flow rates according to the actual pressure within the dripline, making them a cost-effective choice for less variable environments.
Netafim’s systems include advanced controllers and sensors that monitor soil moisture levels, weather conditions and crop needs.

One of the hallmarks of Netafim’s systems is their ability to adapt to varying water requirements based on multiple factors such as soil types, plant needs and field layouts.
“Netafim systems can be customized to accommodate different soil characteristics, such as sandy, loamy or clay soils,” Masarwa explains. “By choosing the emitter flow rates and spacing, the system ensures optimal water distribution to match the soil’s infiltration and retention properties.”
Similarly, the systems are designed to meet the specific water needs of different crops. By delivering precise amounts of water tailored to the plants' growth stages and requirements, Netafim’s systems help in optimizing irrigation efficiency and improving
crop health.

In addition, Netafim systems are designed to adapt to various field layouts, including row crops, broadcast crops and uneven terrains. “The flexibility in emitter placement and the ability to design custom irrigation patterns help ensure uniform water distribution across diverse planting arrangements,” says Masarwa.
Advanced filtration and maintenance
To ensure the smooth operation of drip irrigation systems, Netafim has implemented several measures for water filtration and clog prevention. Filters are a critical component, and they come in various types, including screen filters, disc filters and gravel/sand filters. Each type addresses different levels of particulate matter, protecting the emitters from clogging and ensuring uninterrupted water flow.

Flush valves are also integral to maintaining system performance. Manual flush valves require periodic operation to clean out debris, while automatic flush valves handle this task at regular intervals or when pressure drops. This reduces the need for manual intervention and keeps the system running efficiently.

This reduces the need for manual intervention and keeps the system running efficiently.
Minimizing water waste
One of the core advantages of Netafim’s systems is their ability to minimize water waste. Through precise water delivery, drip emitters reduce evaporation and runoff, ensuring that every drop of water is utilized effectively. Pressure-compensated emitters play a crucial role in maintaining uniform water distribution, preventing areas from being overwatered or underwatered.
Moreover, Netafim’s systems include advanced controllers and sensors that monitor soil moisture levels, weather conditions and crop needs.
“The design of Netafim systems takes into account the specific requirements of the crop, soil type and field layout, ensuring that water is applied where and when it is needed,” Masarwa explains. “This tailored approach minimizes waste and maximizes efficiency.”

Automation and smart controls
The integration of automation and smart controls has further enhanced the efficiency of drip irrigation systems. Automatic timers allow users to set specific irrigation schedules, while soil moisture sensors provide real-time data that adjusts watering based on current soil conditions. Smart controllers offer remote management capabilities through mobile apps or web interfaces, providing greater control and flexibility.
Wireless communication and climate sensors are additional features that help in adjusting irrigation schedules based on weather data and real-time conditions. This level of automation not only reduces labour but also ensures that irrigation is tailored to the precise needs of the crops and environment.

This level of automation not only reduces labour but also ensures that irrigation is tailored to the precise needs of the crops and environment.
Adaptability for seasonal changes
Drip irrigation systems are not static; they can be adjusted to accommodate seasonal changes and varying crop stages. Programmable timers and controllers “allow users to adjust irrigation schedules to account for changing weather conditions and crop needs,” says Masarwa. “For example, during hot, dry periods, the system can be programmed to increase watering frequency or duration, while in cooler, wetter periods, the schedule can be reduced.”
Furthermore, incorporating moisture sensors ensures that the system adapts to real-time soil conditions, preventing overwatering or underwatering.
Furthermore, incorporating moisture sensors ensures that the system adapts to real-time soil conditions, preventing overwatering or underwatering.
Long-term cost considerations
The cost of a drip irrigation system can vary widely based on factors such as crop size, terrain and desired uniformity. While the initial investment might be substantial, the long-term operational and maintenance costs are generally lower compared to traditional irrigation methods. The efficiency of drip irrigation reduces water usage, leading to potential savings on water bills.
Masarwa notes that while maintenance may also involve labour costs, automation and smart controls can reduce the need for manual intervention.
“Investing in high-quality filters to prevent clogging can help avoid costly repairs and maintenance. Regular maintenance of these filters is also necessary,” he says.

“Overall, while the initial investment in a drip irrigation system can be substantial, the long-term operational costs are often lower due to improved water efficiency and reduced labour requirements. Regular maintenance and prompt repairs can further minimize ongoing expenses and enhance the system's longevity.

Regular maintenance and prompt repairs can further minimize ongoing expenses and enhance the system's longevity.
“Taking into account all the points presented here and depending on whether the irrigation system is designed for one or two seasons
or if the equipment is expected to irrigate for many more growing seasons, the distance between emitters and between driplines, whether the crop is located on flat terrain, with small unevenness, on changing topography, or on steep slopes, and whether the farmer desires very high irrigation uniformity, the price can vary from several hundred to few thousand dollars per hectare,” Masarwa adds.
Sustainability and conservation
Netafim’s commitment to sustainability and conservation is evident in their practices and technologies. Precision water delivery reduces overall consumption and waste, while low-pressure design minimizes energy requirements. Drip irrigation also helps prevent soil erosion and degradation, promoting better
soil health.
Targeted fertilization – nutrients, fertilizers and/or chemicals applied directly to the root zone – “reduces the risk of chemical runoff into nearby water sources. This practice minimizes environmental pollution and promotes sustainable farming,” Masarwa explains.
Netafim systems can also be adapted to various soil types, topographies and crop requirements, allowing for efficient water use in diverse environments. This adaptability supports sustainable agricultural practices in different regions.
“The use of durable materials and advanced technology in Netafim systems ensures a long lifespan, reducing the need for frequent replacements and minimizing waste,” adds Masarwa. “And advanced sensors and data analytics provide insights into system performance and water use. This information helps farmers make informed decisions, further enhancing sustainability and resource management.”

This information helps farmers make informed decisions, further enhancing sustainability and resource management.”
Netafim is leading efforts towards zero waste in farmland and sustainable treatment of end-of-life plastics. By using regenerated plastics and operating recycling programs globally, Netafim is working towards a future of full circularity, with the goal of having all driplines contain at least 45 percent recycled content by 2030.
The legacy continues
As the global agricultural landscape continues to evolve, Netafim remains at the cutting edge of precision irrigation technology. With its focus on innovation, sustainability and adaptability, Netafim is not just meeting the current needs of farmers but is also anticipating future challenges.
In the words of Masarwa, “Our mission is to continually innovate to provide solutions to agriculture challenges such as changing climate and water scarcity, giving growers increased accuracy, control and uniformity.” ●

What’s the most common layout of a drip irrigation system?
Every application is different, and therefore Rivulis delivers tailored irrigation solutions meticulously designed to fit diverse application requirements. For instance, a high-density lettuce crop that is replanted each season demands a vastly different system layout versus a comparatively lower-density olive orchard, which is only planted once. Even within the same crop, variations in farm size, field or orchard layout, and planting density necessitate unique, customized approaches to maximize efficiency and yield.

What are the most common emitters or drippers used?
While regional differences exist, generally:
Seasonal crops, like vegetables and strawberries, often use tape (e.g., Rivulis T-Tape) or thin-wall, non-pressure compensating drip lines (e.g., Rivulis D900), which are replaced each season.
Orchards and vineyards typically employ pressure-compensated drip lines (e.g., Rivulis D5000 PC) for long-term durability. These thicker drip lines withstand years of use, and because they are pressure compensated, they offer the ability to irrigate longer rows and sloping terrain.
Indoor agriculture and greenhouses usually utilize online drippers (e.g., Supertif) connected to a tube and peg system for precise, controlled irrigation.

Indoor agriculture and greenhouses usually utilize online drippers (e.g., Supertif) connected to a tube and peg system for precise, controlled irrigation.
It is important to note that in drip irrigation setups for seasonal horticulture, growers can use drip tapes where the dripper is integrated into the tube itself, and drip lines, where molded emitters are inserted into the tube. For drip lines, the cost is proportional to the amount of drip emitters per metre. For drip tapes, the cost of the product does not vary based on the drip emitter spacing. This has enabled a growing trend of high value crop growers to use drip tapes with 10-15 cm drip emitter spacing, coupled with very low flow rates from each dripper which provides even more efficient water application.
Rivulis works in partnership with farmers to manage their unique water and nutrient management plans, which is why we offer the widest variety of drip lines, drip tapes and other water emission products available to meet the unique needs of every customer.

How do flow rates and pressure requirements vary?
Flow rates range from 0.25 l/h per dripper to more than 7 l/h per dripper, and the flow rate and number of required drippers per meter varies by crop, climate and layout. Both factors depend on a plant’s water requirements, planting density, soil type and the full system setup.
After review of a plant’s overall water requirements and consideration of how much it will need at peak growing period and after considering expected water loss to transpiration and evaporation, we look to the soil type and crop planting density. For example, water is less inclined to move laterally on sandy soils than on heavier soils, meaning sandier soils need closer dripper spacing. Planting density is also a determining factor, with vegetables that are closely planted needing lower-flow drippers closer together and orchards requiring comparatively high-flow drippers that can be further apart.

Planting density is also a determining factor, with vegetables that are closely planted needing lower-flow drippers closer together and orchards requiring comparatively high-flow drippers that can be further apart.
What materials for the tubing and fittings are most commonly used?
The most common material for drip lines and tapes is polyethylene because of its ability to be recycled, resistance to chemicals and fertilizers, and is ideal for producing high-quality and reliable products.
How do Rivulis systems adapt to varying water requirements?
Because Rivulis has the widest range of drip lines and tapes of any manufacturer, the system can be tailored to exactly what the plant’s water requirements are. Water requirements are based upon the crop type, the stage within the growing season and the climate. The water requirement does not just vary from crop to crop or region to region, but also varies during the season. Rivulis systems are designed to ensure that growers have the capacity to meet the peak water requirement of the plant during the season, i.e., the period of highest water need.

How is a drip system adjusted for seasonal changes, different crop stages and varying water needs?
Every drip system design begins by understanding the plant's maximum water need based on temperature, crop growth stage and weather (including offset rainfall). The systems are designed to meet peak water requirements and irrigation schedules are calculated accordingly during the season to account for variance of the factors mentioned above. Once a system is in place, we aim to empower farmers with the right data, tools and guidance to make smart decisions for their farm business.
What are some of the long-term operational and maintenance costs

Abed Masarwa,
VP of Products
Netafim
It all began in 1965, a year when the concept of precision irrigation was still a distant dream. Netafim, founded in that pivotal year, set out to revolutionize the way water was delivered to crops. Their innovation was the drip irrigation system – a paradigm shift that promised to change everything from crop yields to resource efficiency. By delivering water directly to the plant's root zone, the system minimized wastage and maximized the effectiveness of each drop. This innovation was not just about watering plants; it was about transforming agriculture itself.
Abed Masarwa, VP of Products at Netafim, encapsulates the essence of this revolution succinctly: “Precision irrigation is all about helping farmers achieve higher yields and better-quality crops, while using less water, fertilizer and energy.”
This philosophy is deeply embedded in every facet of Netafim’s approach, from engineering and project management to their cutting-edge digital farming solutions.
"Our innovative products are designed with the farmer’s needs in mind and offer outstanding value, durability, ease of installation and diversity, tailored to farming operations of any size," Masarwa adds.
Tailoring irrigation to crop and terrain
The success of precision irrigation lies in its adaptability. Unlike traditional irrigation methods that often lead to uneven water distribution and waste, drip irrigation systems can be meticulously designed to meet the specific needs of different crops.
In corn crops, drip irrigation systems usually feature driplines placed along the rows to ensure water is delivered directly to the root zones.

Tailoring irrigation to crop and terrain
The success of precision irrigation lies in its adaptability. Unlike traditional irrigation methods that often lead to uneven water distribution and waste, drip irrigation systems can be meticulously designed to meet the specific needs of different crops.
“The most common layout of a drip irrigation system is typically designed around the specific needs of the crop being cultivated, notes Masarwa. “For row crops (e.g., corn, potatoes, soybeans), the system usually features driplines placed along the rows to ensure that water is delivered directly to the root zones of the plants.”
In contrast, for crops that are broadcast or widely spaced, the layout of the driplines changes. They may be arranged in a grid pattern or spaced out more widely to cover a larger area. This adaptability is crucial for optimizing irrigation performance and resource use, tailored specifically to the type of crop and its planting configuration.
Another significant advancement in drip irrigation technology is the development of various types of emitters, each designed to cater to different needs and conditions. The most common drippers used in drip irrigation systems include pressure-compensated and non-pressure-compensated types.
“The choice of dripper often depends on the specific requirements of the crop, the terrain slope and the irrigation conditions,” says Masarwa.
Netafim systems can be customized to accommodate different soil characteristics, such as sandy, loamy or
clay soils.

Pressure-compensated emitters are particularly valuable in greenhouses, orchards and uneven terrains. They maintain a consistent flow rate despite fluctuations in water pressure, ensuring uniform distribution. This is especially important in challenging topographies where water pressure might vary significantly.
On the other hand, non-pressure-compensated emitters are suitable for systems with stable pressure and flatter terrains. They provide flow rates according to the actual pressure within the dripline, making them a cost-effective choice for less variable environments.
Netafim’s systems include advanced controllers and sensors that monitor soil moisture levels, weather conditions and crop needs.

One of the hallmarks of Netafim’s systems is their ability to adapt to varying water requirements based on multiple factors such as soil types, plant needs and field layouts.
“Netafim systems can be customized to accommodate different soil characteristics, such as sandy, loamy or clay soils,” Masarwa explains. “By choosing the emitter flow rates and spacing, the system ensures optimal water distribution to match the soil’s infiltration and retention properties.”
Similarly, the systems are designed to meet the specific water needs of different crops. By delivering precise amounts of water tailored to the plants' growth stages and requirements, Netafim’s systems help in optimizing irrigation efficiency and improving
crop health.

In addition, Netafim systems are designed to adapt to various field layouts, including row crops, broadcast crops and uneven terrains. “The flexibility in emitter placement and the ability to design custom irrigation patterns help ensure uniform water distribution across diverse planting arrangements,” says Masarwa.
Advanced filtration and maintenance
To ensure the smooth operation of drip irrigation systems, Netafim has implemented several measures for water filtration and clog prevention. Filters are a critical component, and they come in various types, including screen filters, disc filters and gravel/sand filters. Each type addresses different levels of particulate matter, protecting the emitters from clogging and ensuring uninterrupted water flow.

Flush valves are also integral to maintaining system performance. Manual flush valves require periodic operation to clean out debris, while automatic flush valves handle this task at regular intervals or when pressure drops. This reduces the need for manual intervention and keeps the system running efficiently.

Minimizing water waste
One of the core advantages of Netafim’s systems is their ability to minimize water waste. Through precise water delivery, drip emitters reduce evaporation and runoff, ensuring that every drop of water is utilized effectively. Pressure-compensated emitters play a crucial role in maintaining uniform water distribution, preventing areas from being overwatered or underwatered.
Moreover, Netafim’s systems include advanced controllers and sensors that monitor soil moisture levels, weather conditions and crop needs.
“The design of Netafim systems takes into account the specific requirements of the crop, soil type and field layout, ensuring that water is applied where and when it is needed,” Masarwa explains. “This tailored approach minimizes waste and maximizes efficiency.”

Automation and smart controls
The integration of automation and smart controls has further enhanced the efficiency of drip irrigation systems. Automatic timers allow users to set specific irrigation schedules, while soil moisture sensors provide real-time data that adjusts watering based on current soil conditions. Smart controllers offer remote management capabilities through mobile apps or web interfaces, providing greater control and flexibility.
Wireless communication and climate sensors are additional features that help in adjusting irrigation schedules based on weather data and real-time conditions. This level of automation not only reduces labour but also ensures that irrigation is tailored to the precise needs of the crops and environment.

This level of automation not only reduces labour but also ensures that irrigation is tailored to the precise needs of the crops and environment.
Adaptability for seasonal changes
Drip irrigation systems are not static; they can be adjusted to accommodate seasonal changes and varying crop stages. Programmable timers and controllers “allow users to adjust irrigation schedules to account for changing weather conditions and crop needs,” says Masarwa. “For example, during hot, dry periods, the system can be programmed to increase watering frequency or duration, while in cooler, wetter periods, the schedule can be reduced.”
Furthermore, incorporating moisture sensors ensures that the system adapts to real-time soil conditions, preventing overwatering or underwatering.
Furthermore, incorporating moisture sensors ensures that the system adapts to real-time soil conditions, preventing overwatering or underwatering.
Long-term cost considerations
The cost of a drip irrigation system can vary widely based on factors such as crop size, terrain and desired uniformity. While the initial investment might be substantial, the long-term operational and maintenance costs are generally lower compared to traditional irrigation methods. The efficiency of drip irrigation reduces water usage, leading to potential savings on water bills.
Masarwa notes that while maintenance may also involve labour costs, automation and smart controls can reduce the need for manual intervention.
“Investing in high-quality filters to prevent clogging can help avoid costly repairs and maintenance. Regular maintenance of these filters is also necessary,” he says.

Regular maintenance and prompt repairs can further minimize ongoing expenses and enhance the system's longevity.
“Taking into account all the points presented here and depending on whether the irrigation system is designed for one or two seasons
or if the equipment is expected to irrigate for many more growing seasons, the distance between emitters and between driplines, whether the crop is located on flat terrain, with small unevenness, on changing topography, or on steep slopes, and whether the farmer desires very high irrigation uniformity, the price can vary from several hundred to few thousand dollars per hectare,” Masarwa adds.
Sustainability and conservation
Netafim’s commitment to sustainability and conservation is evident in their practices and technologies. Precision water delivery reduces overall consumption and waste, while low-pressure design minimizes energy requirements. Drip irrigation also helps prevent soil erosion and degradation, promoting better
soil health.
Targeted fertilization – nutrients, fertilizers and/or chemicals applied directly to the root zone – “reduces the risk of chemical runoff into nearby water sources. This practice minimizes environmental pollution and promotes sustainable farming,” Masarwa explains.
Netafim systems can also be adapted to various soil types, topographies and crop requirements, allowing for efficient water use in diverse environments. This adaptability supports sustainable agricultural practices in different regions.
“The use of durable materials and advanced technology in Netafim systems ensures a long lifespan, reducing the need for frequent replacements and minimizing waste,” adds Masarwa. “And advanced sensors and data analytics provide insights into system performance and water use. This information helps farmers make informed decisions, further enhancing sustainability and resource management.”

This information helps farmers make informed decisions, further enhancing sustainability and resource management.”
Netafim is leading efforts towards zero waste in farmland and sustainable treatment of end-of-life plastics. By using regenerated plastics and operating recycling programs globally, Netafim is working towards a future of full circularity, with the goal of having all driplines contain at least 45 percent recycled content by 2030.
The legacy continues
As the global agricultural landscape continues to evolve, Netafim remains at the cutting edge of precision irrigation technology. With its focus on innovation, sustainability and adaptability, Netafim is not just meeting the current needs of farmers but is also anticipating future challenges.
In the words of Masarwa, “Our mission is to continually innovate to provide solutions to agriculture challenges such as changing climate and water scarcity, giving growers increased accuracy, control and uniformity.” ●

What are the most common emitters or drippers used?
While regional differences exist, generally:
Seasonal crops, like vegetables and strawberries, often use tape (e.g., Rivulis T-Tape) or thin-wall, non-pressure compensating drip lines (e.g., Rivulis D900), which are replaced each season.
Orchards and vineyards typically employ pressure-compensated drip lines (e.g., Rivulis D5000 PC) for long-term durability. These thicker drip lines withstand years of use, and because they are pressure compensated, they offer the ability to irrigate longer rows and sloping terrain.
Indoor agriculture and greenhouses usually utilize online drippers (e.g., Supertif) connected to a tube and peg system for precise, controlled irrigation.

Indoor agriculture and greenhouses usually utilize online drippers (e.g., Supertif) connected to a tube and peg system for precise, controlled irrigation.
It is important to note that in drip irrigation setups for seasonal horticulture, growers can use drip tapes where the dripper is integrated into the tube itself, and drip lines, where molded emitters are inserted into the tube. For drip lines, the cost is proportional to the amount of drip emitters per metre. For drip tapes, the cost of the product does not vary based on the drip emitter spacing. This has enabled a growing trend of high value crop growers to use drip tapes with 10-15 cm drip emitter spacing, coupled with very low flow rates from each dripper which provides even more efficient water application.
Rivulis works in partnership with farmers to manage their unique water and nutrient management plans, which is why we offer the widest variety of drip lines, drip tapes and other water emission products available to meet the unique needs of every customer.

How do flow rates and pressure requirements vary?
Flow rates range from 0.25 l/h per dripper to more than 7 l/h per dripper, and the flow rate and number of required drippers per meter varies by crop, climate and layout. Both factors depend on a plant’s water requirements, planting density, soil type and the full system setup.
After review of a plant’s overall water requirements and consideration of how much it will need at peak growing period and after considering expected water loss to transpiration and evaporation, we look to the soil type and crop planting density. For example, water is less inclined to move laterally on sandy soils than on heavier soils, meaning sandier soils need closer dripper spacing. Planting density is also a determining factor, with vegetables that are closely planted needing lower-flow drippers closer together and orchards requiring comparatively high-flow drippers that can be further apart.

Planting density is also a determining factor, with vegetables that are closely planted needing lower-flow drippers closer together and orchards requiring comparatively high-flow drippers that can be further apart.
What materials for the tubing and fittings are most commonly used?
The most common material for drip lines and tapes is polyethylene because of its ability to be recycled, resistance to chemicals and fertilizers, and is ideal for producing high-quality and reliable products.
How do Rivulis systems adapt to varying water requirements?
Because Rivulis has the widest range of drip lines and tapes of any manufacturer, the system can be tailored to exactly what the plant’s water requirements are. Water requirements are based upon the crop type, the stage within the growing season and the climate. The water requirement does not just vary from crop to crop or region to region, but also varies during the season. Rivulis systems are designed to ensure that growers have the capacity to meet the peak water requirement of the plant during the season, i.e., the period of highest water need.

How is a drip system adjusted for seasonal changes, different crop stages and varying water needs?
Every drip system design begins by understanding the plant's maximum water need based on temperature, crop growth stage and weather (including offset rainfall). The systems are designed to meet peak water requirements and irrigation schedules are calculated accordingly during the season to account for variance of the factors mentioned above. Once a system is in place, we aim to empower farmers with the right data, tools and guidance to make smart decisions for their farm business.

The program has already supported 10 farmers on 1,250 hectares, with a goal to reach 25 farmers and 3,500 hectares
in 2024.
Our sustainability promise also extends to the production of our products. Our Full Circle Sustainability program encompasses our strategies to increase circularity of resources, particularly plastics. We operate programs in Australia, France, Israel, Turkey and the U.S., with plans in place to extend to other markets. As part of this approach, we will soon launch a state-of-the-art recycling facility in North America, which will have the capacity to recover our products and integrate post-consumer and post-industrial waste into our raw materials.
We are continually launching products with more recycled content and use less plastic along our full supply chain. For example, we recently launched Rivulis T-Tape White in Europe, the first thin wall drip product made with at least 50 percent recycled materials. This product offers the same trusted performance in water application, clogging resistance, strength and customizable configurations, in a more environmentally friendly option that farmers want. Additional details can be found here.

Abed Masarwa,
VP of Products
Netafim
It all began in 1965, a year when the concept of precision irrigation was still a distant dream. Netafim, founded in that pivotal year, set out to revolutionize the way water was delivered to crops. Their innovation was the drip irrigation system – a paradigm shift that promised to change everything from crop yields to resource efficiency. By delivering water directly to the plant's root zone, the system minimized wastage and maximized the effectiveness of each drop. This innovation was not just about watering plants; it was about transforming agriculture itself.
Abed Masarwa, VP of Products at Netafim, encapsulates the essence of this revolution succinctly: “Precision irrigation is all about helping farmers achieve higher yields and better-quality crops, while using less water, fertilizer and energy.”
This philosophy is deeply embedded in every facet of Netafim’s approach, from engineering and project management to their cutting-edge digital farming solutions.
"Our innovative products are designed with the farmer’s needs in mind and offer outstanding value, durability, ease of installation and diversity, tailored to farming operations of any size," Masarwa adds.
Tailoring irrigation to crop and terrain
The success of precision irrigation lies in its adaptability. Unlike traditional irrigation methods that often lead to uneven water distribution and waste, drip irrigation systems can be meticulously designed to meet the specific needs of different crops.
In corn crops, drip irrigation systems usually feature driplines placed along the rows to ensure water is delivered directly to the root zones.

Tailoring irrigation to crop and terrain
The success of precision irrigation lies in its adaptability. Unlike traditional irrigation methods that often lead to uneven water distribution and waste, drip irrigation systems can be meticulously designed to meet the specific needs of different crops.
“The most common layout of a drip irrigation system is typically designed around the specific needs of the crop being cultivated, notes Masarwa. “For row crops (e.g., corn, potatoes, soybeans), the system usually features driplines placed along the rows to ensure that water is delivered directly to the root zones of the plants.”
In contrast, for crops that are broadcast or widely spaced, the layout of the driplines changes. They may be arranged in a grid pattern or spaced out more widely to cover a larger area. This adaptability is crucial for optimizing irrigation performance and resource use, tailored specifically to the type of crop and its planting configuration.
Another significant advancement in drip irrigation technology is the development of various types of emitters, each designed to cater to different needs and conditions. The most common drippers used in drip irrigation systems include pressure-compensated and non-pressure-compensated types.
“The choice of dripper often depends on the specific requirements of the crop, the terrain slope and the irrigation conditions,” says Masarwa.
Netafim systems can be customized to accommodate different soil characteristics, such as sandy, loamy or
clay soils.

Pressure-compensated emitters are particularly valuable in greenhouses, orchards and uneven terrains. They maintain a consistent flow rate despite fluctuations in water pressure, ensuring uniform distribution. This is especially important in challenging topographies where water pressure might vary significantly.
On the other hand, non-pressure-compensated emitters are suitable for systems with stable pressure and flatter terrains. They provide flow rates according to the actual pressure within the dripline, making them a cost-effective choice for less variable environments.
Netafim’s systems include advanced controllers and sensors that monitor soil moisture levels, weather conditions and crop needs.

One of the hallmarks of Netafim’s systems is their ability to adapt to varying water requirements based on multiple factors such as soil types, plant needs and field layouts.
“Netafim systems can be customized to accommodate different soil characteristics, such as sandy, loamy or clay soils,” Masarwa explains. “By choosing the emitter flow rates and spacing, the system ensures optimal water distribution to match the soil’s infiltration and retention properties.”
Similarly, the systems are designed to meet the specific water needs of different crops. By delivering precise amounts of water tailored to the plants' growth stages and requirements, Netafim’s systems help in optimizing irrigation efficiency and improving
crop health.

In addition, Netafim systems are designed to adapt to various field layouts, including row crops, broadcast crops and uneven terrains. “The flexibility in emitter placement and the ability to design custom irrigation patterns help ensure uniform water distribution across diverse planting arrangements,” says Masarwa.
Advanced filtration and maintenance
To ensure the smooth operation of drip irrigation systems, Netafim has implemented several measures for water filtration and clog prevention. Filters are a critical component, and they come in various types, including screen filters, disc filters and gravel/sand filters. Each type addresses different levels of particulate matter, protecting the emitters from clogging and ensuring uninterrupted water flow.

Flush valves are also integral to maintaining system performance. Manual flush valves require periodic operation to clean out debris, while automatic flush valves handle this task at regular intervals or when pressure drops. This reduces the need for manual intervention and keeps the system running efficiently.

This reduces the need for manual intervention and keeps the system running efficiently.
Minimizing water waste
One of the core advantages of Netafim’s systems is their ability to minimize water waste. Through precise water delivery, drip emitters reduce evaporation and runoff, ensuring that every drop of water is utilized effectively. Pressure-compensated emitters play a crucial role in maintaining uniform water distribution, preventing areas from being overwatered or underwatered.
Moreover, Netafim’s systems include advanced controllers and sensors that monitor soil moisture levels, weather conditions and crop needs.
“The design of Netafim systems takes into account the specific requirements of the crop, soil type and field layout, ensuring that water is applied where and when it is needed,” Masarwa explains. “This tailored approach minimizes waste and maximizes efficiency.”

Automation and smart controls
The integration of automation and smart controls has further enhanced the efficiency of drip irrigation systems. Automatic timers allow users to set specific irrigation schedules, while soil moisture sensors provide real-time data that adjusts watering based on current soil conditions. Smart controllers offer remote management capabilities through mobile apps or web interfaces, providing greater control and flexibility.
Wireless communication and climate sensors are additional features that help in adjusting irrigation schedules based on weather data and real-time conditions. This level of automation not only reduces labour but also ensures that irrigation is tailored to the precise needs of the crops and environment.

This level of automation not only reduces labour but also ensures that irrigation is tailored to the precise needs of the crops and environment.
Adaptability for seasonal changes
Drip irrigation systems are not static; they can be adjusted to accommodate seasonal changes and varying crop stages. Programmable timers and controllers “allow users to adjust irrigation schedules to account for changing weather conditions and crop needs,” says Masarwa. “For example, during hot, dry periods, the system can be programmed to increase watering frequency or duration, while in cooler, wetter periods, the schedule can be reduced.”
Furthermore, incorporating moisture sensors ensures that the system adapts to real-time soil conditions, preventing overwatering or underwatering.
Furthermore, incorporating moisture sensors ensures that the system adapts to real-time soil conditions, preventing overwatering or underwatering.
Long-term cost considerations
The cost of a drip irrigation system can vary widely based on factors such as crop size, terrain and desired uniformity. While the initial investment might be substantial, the long-term operational and maintenance costs are generally lower compared to traditional irrigation methods. The efficiency of drip irrigation reduces water usage, leading to potential savings on water bills.
Masarwa notes that while maintenance may also involve labour costs, automation and smart controls can reduce the need for manual intervention.
“Investing in high-quality filters to prevent clogging can help avoid costly repairs and maintenance. Regular maintenance of these filters is also necessary,” he says.

“Overall, while the initial investment in a drip irrigation system can be substantial, the long-term operational costs are often lower due to improved water efficiency and reduced labour requirements. Regular maintenance and prompt repairs can further minimize ongoing expenses and enhance the system's longevity.
“Overall, while the initial investment in a drip irrigation system can be substantial, the long-term operational costs are often lower due to improved water efficiency and reduced labour requirements. Regular maintenance and prompt repairs can further minimize ongoing expenses and enhance the system's longevity.
“Taking into account all the points presented here and depending on whether the irrigation system is designed for one or two seasons
or if the equipment is expected to irrigate for many more growing seasons, the distance between emitters and between driplines, whether the crop is located on flat terrain, with small unevenness, on changing topography, or on steep slopes, and whether the farmer desires very high irrigation uniformity, the price can vary from several hundred to few thousand dollars per hectare,” Masarwa adds.
Sustainability and conservation
Netafim’s commitment to sustainability and conservation is evident in their practices and technologies. Precision water delivery reduces overall consumption and waste, while low-pressure design minimizes energy requirements. Drip irrigation also helps prevent soil erosion and degradation, promoting better
soil health.
Targeted fertilization – nutrients, fertilizers and/or chemicals applied directly to the root zone – “reduces the risk of chemical runoff into nearby water sources. This practice minimizes environmental pollution and promotes sustainable farming,” Masarwa explains.
Netafim systems can also be adapted to various soil types, topographies and crop requirements, allowing for efficient water use in diverse environments. This adaptability supports sustainable agricultural practices in different regions.
“The use of durable materials and advanced technology in Netafim systems ensures a long lifespan, reducing the need for frequent replacements and minimizing waste,” adds Masarwa. “And advanced sensors and data analytics provide insights into system performance and water use. This information helps farmers make informed decisions, further enhancing sustainability and resource management.”

This information helps farmers make informed decisions, further enhancing sustainability and resource management.”
Netafim is leading efforts towards zero waste in farmland and sustainable treatment of end-of-life plastics. By using regenerated plastics and operating recycling programs globally, Netafim is working towards a future of full circularity, with the goal of having all driplines contain at least 45 percent recycled content by 2030.
The legacy continues
As the global agricultural landscape continues to evolve, Netafim remains at the cutting edge of precision irrigation technology. With its focus on innovation, sustainability and adaptability, Netafim is not just meeting the current needs of farmers but is also anticipating future challenges.
In the words of Masarwa, “Our mission is to continually innovate to provide solutions to agriculture challenges such as changing climate and water scarcity, giving growers increased accuracy, control and uniformity.” ●

What are the most common emitters or drippers used?
While regional differences exist, generally:
Seasonal crops, like vegetables and strawberries, often use tape (e.g., Rivulis T-Tape) or thin-wall, non-pressure compensating drip lines (e.g., Rivulis D900), which are replaced each season.
Orchards and vineyards typically employ pressure-compensated drip lines (e.g., Rivulis D5000 PC) for long-term durability. These thicker drip lines withstand years of use, and because they are pressure compensated, they offer the ability to irrigate longer rows and sloping terrain.
Indoor agriculture and greenhouses usually utilize online drippers (e.g., Supertif) connected to a tube and peg system for precise, controlled irrigation.

Indoor agriculture and greenhouses usually utilize online drippers (e.g., Supertif) connected to a tube and peg system for precise, controlled irrigation.
It is important to note that in drip irrigation setups for seasonal horticulture, growers can use drip tapes where the dripper is integrated into the tube itself, and drip lines, where molded emitters are inserted into the tube. For drip lines, the cost is proportional to the amount of drip emitters per metre. For drip tapes, the cost of the product does not vary based on the drip emitter spacing. This has enabled a growing trend of high value crop growers to use drip tapes with 10-15 cm drip emitter spacing, coupled with very low flow rates from each dripper which provides even more efficient water application.
Rivulis works in partnership with farmers to manage their unique water and nutrient management plans, which is why we offer the widest variety of drip lines, drip tapes and other water emission products available to meet the unique needs of every customer.

How do flow rates and pressure requirements vary?
Flow rates range from 0.25 l/h per dripper to more than 7 l/h per dripper, and the flow rate and number of required drippers per meter varies by crop, climate and layout. Both factors depend on a plant’s water requirements, planting density, soil type and the full system setup.
After review of a plant’s overall water requirements and consideration of how much it will need at peak growing period and after considering expected water loss to transpiration and evaporation, we look to the soil type and crop planting density. For example, water is less inclined to move laterally on sandy soils than on heavier soils, meaning sandier soils need closer dripper spacing. Planting density is also a determining factor, with vegetables that are closely planted needing lower-flow drippers closer together and orchards requiring comparatively high-flow drippers that can be further apart.

What materials for the tubing and fittings are most commonly used?
The most common material for drip lines and tapes is polyethylene because of its ability to be recycled, resistance to chemicals and fertilizers, and is ideal for producing high-quality and reliable products.
How do Rivulis systems adapt to varying water requirements?
Because Rivulis has the widest range of drip lines and tapes of any manufacturer, the system can be tailored to exactly what the plant’s water requirements are. Water requirements are based upon the crop type, the stage within the growing season and the climate. The water requirement does not just vary from crop to crop or region to region, but also varies during the season. Rivulis systems are designed to ensure that growers have the capacity to meet the peak water requirement of the plant during the season, i.e., the period of highest water need.

How is a drip system adjusted for seasonal changes, different crop stages and varying water needs?
Every drip system design begins by understanding the plant's maximum water need based on temperature, crop growth stage and weather (including offset rainfall). The systems are designed to meet peak water requirements and irrigation schedules are calculated accordingly during the season to account for variance of the factors mentioned above. Once a system is in place, we aim to empower farmers with the right data, tools and guidance to make smart decisions for their farm business.
What are some of the long-term operational and maintenance costs
Because Rivulis offers systems, tools and solutions tailored to meet the needs of farms both big and small, costs vary.

Abed Masarwa,
VP of Products
Netafim
It all began in 1965, a year when the concept of precision irrigation was still a distant dream. Netafim, founded in that pivotal year, set out to revolutionize the way water was delivered to crops. Their innovation was the drip irrigation system – a paradigm shift that promised to change everything from crop yields to resource efficiency. By delivering water directly to the plant's root zone, the system minimized wastage and maximized the effectiveness of each drop. This innovation was not just about watering plants; it was about transforming agriculture itself.
Abed Masarwa, VP of Products at Netafim, encapsulates the essence of this revolution succinctly: “Precision irrigation is all about helping farmers achieve higher yields and better-quality crops, while using less water, fertilizer and energy.”
This philosophy is deeply embedded in every facet of Netafim’s approach, from engineering and project management to their cutting-edge digital farming solutions.
"Our innovative products are designed with the farmer’s needs in mind and offer outstanding value, durability, ease of installation and diversity, tailored to farming operations of any size," Masarwa adds.
Tailoring irrigation to crop and terrain
The success of precision irrigation lies in its adaptability. Unlike traditional irrigation methods that often lead to uneven water distribution and waste, drip irrigation systems can be meticulously designed to meet the specific needs of different crops.
In corn crops, drip irrigation systems usually feature driplines placed along the rows to ensure water is delivered directly to the root zones.

Tailoring irrigation to crop and terrain
The success of precision irrigation lies in its adaptability. Unlike traditional irrigation methods that often lead to uneven water distribution and waste, drip irrigation systems can be meticulously designed to meet the specific needs of different crops.
“The most common layout of a drip irrigation system is typically designed around the specific needs of the crop being cultivated, notes Masarwa. “For row crops (e.g., corn, potatoes, soybeans), the system usually features driplines placed along the rows to ensure that water is delivered directly to the root zones of the plants.”
In contrast, for crops that are broadcast or widely spaced, the layout of the driplines changes. They may be arranged in a grid pattern or spaced out more widely to cover a larger area. This adaptability is crucial for optimizing irrigation performance and resource use, tailored specifically to the type of crop and its planting configuration.
Another significant advancement in drip irrigation technology is the development of various types of emitters, each designed to cater to different needs and conditions. The most common drippers used in drip irrigation systems include pressure-compensated and non-pressure-compensated types.
“The choice of dripper often depends on the specific requirements of the crop, the terrain slope and the irrigation conditions,” says Masarwa.
Netafim systems can be customized to accommodate different soil characteristics, such as sandy, loamy or
clay soils.

Pressure-compensated emitters are particularly valuable in greenhouses, orchards and uneven terrains. They maintain a consistent flow rate despite fluctuations in water pressure, ensuring uniform distribution. This is especially important in challenging topographies where water pressure might vary significantly.
On the other hand, non-pressure-compensated emitters are suitable for systems with stable pressure and flatter terrains. They provide flow rates according to the actual pressure within the dripline, making them a cost-effective choice for less variable environments.
Netafim’s systems include advanced controllers and sensors that monitor soil moisture levels, weather conditions and crop needs.

One of the hallmarks of Netafim’s systems is their ability to adapt to varying water requirements based on multiple factors such as soil types, plant needs and field layouts.
“Netafim systems can be customized to accommodate different soil characteristics, such as sandy, loamy or clay soils,” Masarwa explains. “By choosing the emitter flow rates and spacing, the system ensures optimal water distribution to match the soil’s infiltration and retention properties.”
Similarly, the systems are designed to meet the specific water needs of different crops. By delivering precise amounts of water tailored to the plants' growth stages and requirements, Netafim’s systems help in optimizing irrigation efficiency and improving
crop health.

In addition, Netafim systems are designed to adapt to various field layouts, including row crops, broadcast crops and uneven terrains. “The flexibility in emitter placement and the ability to design custom irrigation patterns help ensure uniform water distribution across diverse planting arrangements,” says Masarwa.
Advanced filtration and maintenance
To ensure the smooth operation of drip irrigation systems, Netafim has implemented several measures for water filtration and clog prevention. Filters are a critical component, and they come in various types, including screen filters, disc filters and gravel/sand filters. Each type addresses different levels of particulate matter, protecting the emitters from clogging and ensuring uninterrupted water flow.

Flush valves are also integral to maintaining system performance. Manual flush valves require periodic operation to clean out debris, while automatic flush valves handle this task at regular intervals or when pressure drops. This reduces the need for manual intervention and keeps the system running efficiently.

Minimizing water waste
One of the core advantages of Netafim’s systems is their ability to minimize water waste. Through precise water delivery, drip emitters reduce evaporation and runoff, ensuring that every drop of water is utilized effectively. Pressure-compensated emitters play a crucial role in maintaining uniform water distribution, preventing areas from being overwatered or underwatered.
Moreover, Netafim’s systems include advanced controllers and sensors that monitor soil moisture levels, weather conditions and crop needs.
“The design of Netafim systems takes into account the specific requirements of the crop, soil type and field layout, ensuring that water is applied where and when it is needed,” Masarwa explains. “This tailored approach minimizes waste and maximizes efficiency.”

Automation and smart controls
The integration of automation and smart controls has further enhanced the efficiency of drip irrigation systems. Automatic timers allow users to set specific irrigation schedules, while soil moisture sensors provide real-time data that adjusts watering based on current soil conditions. Smart controllers offer remote management capabilities through mobile apps or web interfaces, providing greater control and flexibility.
Wireless communication and climate sensors are additional features that help in adjusting irrigation schedules based on weather data and real-time conditions. This level of automation not only reduces labour but also ensures that irrigation is tailored to the precise needs of the crops and environment.

This level of automation not only reduces labour but also ensures that irrigation is tailored to the precise needs of the crops and environment.
Adaptability for seasonal changes
Drip irrigation systems are not static; they can be adjusted to accommodate seasonal changes and varying crop stages. Programmable timers and controllers “allow users to adjust irrigation schedules to account for changing weather conditions and crop needs,” says Masarwa. “For example, during hot, dry periods, the system can be programmed to increase watering frequency or duration, while in cooler, wetter periods, the schedule can be reduced.”
Furthermore, incorporating moisture sensors ensures that the system adapts to real-time soil conditions, preventing overwatering or underwatering.
Furthermore, incorporating moisture sensors ensures that the system adapts to real-time soil conditions, preventing overwatering or underwatering.
Long-term cost considerations
The cost of a drip irrigation system can vary widely based on factors such as crop size, terrain and desired uniformity. While the initial investment might be substantial, the long-term operational and maintenance costs are generally lower compared to traditional irrigation methods. The efficiency of drip irrigation reduces water usage, leading to potential savings on water bills.
Masarwa notes that while maintenance may also involve labour costs, automation and smart controls can reduce the need for manual intervention.
“Investing in high-quality filters to prevent clogging can help avoid costly repairs and maintenance. Regular maintenance of these filters is also necessary,” he says.

Regular maintenance and prompt repairs can further minimize ongoing expenses and enhance the system's longevity.
“Taking into account all the points presented here and depending on whether the irrigation system is designed for one or two seasons
or if the equipment is expected to irrigate for many more growing seasons, the distance between emitters and between driplines, whether the crop is located on flat terrain, with small unevenness, on changing topography, or on steep slopes, and whether the farmer desires very high irrigation uniformity, the price can vary from several hundred to few thousand dollars per hectare,” Masarwa adds.
Sustainability and conservation
Netafim’s commitment to sustainability and conservation is evident in their practices and technologies. Precision water delivery reduces overall consumption and waste, while low-pressure design minimizes energy requirements. Drip irrigation also helps prevent soil erosion and degradation, promoting better
soil health.
Targeted fertilization – nutrients, fertilizers and/or chemicals applied directly to the root zone – “reduces the risk of chemical runoff into nearby water sources. This practice minimizes environmental pollution and promotes sustainable farming,” Masarwa explains.
Netafim systems can also be adapted to various soil types, topographies and crop requirements, allowing for efficient water use in diverse environments. This adaptability supports sustainable agricultural practices in different regions.
“The use of durable materials and advanced technology in Netafim systems ensures a long lifespan, reducing the need for frequent replacements and minimizing waste,” adds Masarwa. “And advanced sensors and data analytics provide insights into system performance and water use. This information helps farmers make informed decisions, further enhancing sustainability and resource management.”

What are the most common emitters or drippers used?
While regional differences exist, generally:
Seasonal crops, like vegetables and strawberries, often use tape (e.g., Rivulis T-Tape) or thin-wall, non-pressure compensating drip lines (e.g., Rivulis D900), which are replaced each season.
Orchards and vineyards typically employ pressure-compensated drip lines (e.g., Rivulis D5000 PC) for long-term durability. These thicker drip lines withstand years of use, and because they are pressure compensated, they offer the ability to irrigate longer rows and sloping terrain.
Indoor agriculture and greenhouses usually utilize online drippers (e.g., Supertif) connected to a tube and peg system for precise, controlled irrigation.

Indoor agriculture and greenhouses usually utilize online drippers (e.g., Supertif) connected to a tube and peg system for precise, controlled irrigation.
It is important to note that in drip irrigation setups for seasonal horticulture, growers can use drip tapes where the dripper is integrated into the tube itself, and drip lines, where molded emitters are inserted into the tube. For drip lines, the cost is proportional to the amount of drip emitters per metre. For drip tapes, the cost of the product does not vary based on the drip emitter spacing. This has enabled a growing trend of high value crop growers to use drip tapes with 10-15 cm drip emitter spacing, coupled with very low flow rates from each dripper which provides even more efficient water application.
Rivulis works in partnership with farmers to manage their unique water and nutrient management plans, which is why we offer the widest variety of drip lines, drip tapes and other water emission products available to meet the unique needs of every customer.

How do flow rates and pressure requirements vary?
Flow rates range from 0.25 l/h per dripper to more than 7 l/h per dripper, and the flow rate and number of required drippers per meter varies by crop, climate and layout. Both factors depend on a plant’s water requirements, planting density, soil type and the full system setup.
After review of a plant’s overall water requirements and consideration of how much it will need at peak growing period and after considering expected water loss to transpiration and evaporation, we look to the soil type and crop planting density. For example, water is less inclined to move laterally on sandy soils than on heavier soils, meaning sandier soils need closer dripper spacing. Planting density is also a determining factor, with vegetables that are closely planted needing lower-flow drippers closer together and orchards requiring comparatively high-flow drippers that can be further apart.

What materials for the tubing and fittings are most commonly used?
The most common material for drip lines and tapes is polyethylene because of its ability to be recycled, resistance to chemicals and fertilizers, and is ideal for producing high-quality and reliable products.
How do Rivulis systems adapt to varying water requirements?
Because Rivulis has the widest range of drip lines and tapes of any manufacturer, the system can be tailored to exactly what the plant’s water requirements are. Water requirements are based upon the crop type, the stage within the growing season and the climate. The water requirement does not just vary from crop to crop or region to region, but also varies during the season. Rivulis systems are designed to ensure that growers have the capacity to meet the peak water requirement of the plant during the season, i.e., the period of highest water need.

We analyze the irrigation water (inorganic and organic content, dissolved minerals, salinity and pH) to prescribe the best filtration and treatment for precise, uniform and reliable irrigation, ensuring our customers are set up for success.
Drip systems use filtration technology – media, screen or disc – to protect the drip lines/tapes from contaminants. These can be automatic, semi-automatic or manual, and are determined based on the water source and system design.
How does Rivulis’ systems minimize water waste?
Water conservation is a key aspect of our business, achieved through the efficiency that drip irrigation provides. Our drippers are designed to deliver the right amount of water and fertilizer to each plant every time. Water is applied directly to the root zone to minimize evaporation and run-off, making the most of natural resources and costly inputs.

How is a drip system adjusted for seasonal changes, different crop stages and varying water needs?
Every drip system design begins by understanding the plant's maximum water need based on temperature, crop growth stage and weather (including offset rainfall). The systems are designed to meet peak water requirements and irrigation schedules are calculated accordingly during the season to account for variance of the factors mentioned above. Once a system is in place, we aim to empower farmers with the right data, tools and guidance to make smart decisions for their farm business.
What are some of the long-term operational and maintenance costs
Because Rivulis offers systems, tools and solutions tailored to meet the needs of farms both big and small, costs vary. However, no matter the size of the project, from turn-key automated systems for large enterprises to manual operation or gravitational-based drip kit solutions for small landholders, Rivulis continues to partner with our customers even after the system
is complete.
Additionally, we understand the need for farmers to use financial resources efficiently. Our systems help to eliminate unnecessary water use or over-fertilization, leading to cost savings and increased yields, resulting in improved profitability. Additionally, through Rivulis Impact Finance, we are connecting the agri-food ecosystem with financial stakeholders to help growers afford micro irrigation solutions.
