Netafim Introduces the FIRST Drip Irrigation System Utilizing Dairy Effluent

SDI-E Turns Waste Into Value

A Circular Economy Model Driving Sustainability in Dairy Manure Management

Challenging traditional methods of irrigation, SDI-E enables the efficient use of water and on-farm nutrients, minimizing the impact on the environment; meeting the needs of the modern Dairy Farmer. SDI-E is the subsurface drip irrigation solution that allows the consistent and reliable application of dairy effluent as a nutrient-rich fertilizer. Farmers have the capacity to sustainably grow feed crops utilizing on-farm nutrients producing higher quality and higher yields.

Cost share funding is available through EQIP, SWEEP, and Netafim Financial.

The Challenge for Dairy Farmers

Dairy Farmers needed a solution to manage manure waste, utilizing it to fertlize feed crops. At the same time, the California drought pushed for solutions to use water more efficiently.

Got Milk? California Dairy Farmers churn out 21% of Americas milk supply. The exceptional season of record breaking drought has been rough on California Dairies, driving up the cost of feed and water. Consumers feel the effects at the grocery store with an average cost of a gallon of milk between $3-$4. Facing incredible water challenges, farmers have been forced to let thousands of acres of forage crop lie parched and unplanted, making feed for livestock scarce and expensive. In addition to feed cost, farmers are paying more for water.

Drip for Dairy Farmers

Winner of the 2020 U.S. Dairy Sustainability Award for Outstanding Community Impact, the innovative system uses advanced filtration and proprietary, patent-pending technology developed by Netafim to blend dairy wastewater with fresh water at an optimum ratio through monitoring of the electrical conductivity (EC) in the water as it passes by a sensor. As the EC of the water changes, Netafim’s system is able to make real-time adjustments to the blending valves in order to keep the fertilizer mixture in a prescribed ratio as it is delivered to the plant’s roots though drip irrigation tubing buried below the surface. This process not only re-uses water, but also recycles manure as a natural crop nutrient and soil builder, reducing the need for commercial fertilizer.

Benefits of Utilizing On-Farm Nutrients

In one year, an average Dairy Farm with 1,250 Holstein Milk Cows can produce about 217,250 lbs of nutrients, enough for 800 acres of field or silage corn. Recycling this organic waste can benefit the environment and farm operations in numerous ways.

SDI-E Helps Farmers Meet Challenges and Improve Smart Water Practices

Dairy Farmers face many challenges, one of which is the use of readily available, nutrient-rich liquid effluent as a forage crop fertilizer. With SDI-E, farmers tackle stricter environmental regulations benefiting the environment and improving operational efficiencies.


"The SDI-E system presents a great opportunity for dairies nationwide to improve their operations and increase productivity while also achieving the environmental sustainability needs of the industry."

Domonic Rossini, Agronomy Leader, West


Successful SDI-E Implementation Requires the Following Set-up

  • Maximum 5 Cows to 1 Acre Ratio for effective nutrient management
  • The use of 2 lagoons or settling ponds for effluent water filtration
  • Netafim's Patented Blending Control Technology for fresh/effluent water blending
  • Use of sprinklers or flood irrigation for germination, then transition to SDI-E
  • Optimized and engineered water intake
  • Operations focu on dripline maintenance

SDI-E Irrigation System Overview

Subsurface Drip Irrigation is a management tool that allows precise control over the root zone environment of your crop. This added management control results in consistently higher yields and better quality. In addition, better water and nutrient management can help reduce fertilizer inputs, water needs, and runoff. Scroll through and learn more about the components required for an SDI-E system. To determine a system configuration suitable for your crops, a Netafim Authorized Digital Farming Dealer can determine what configuration is best.

Make Your Farming Operation More Profitable

Subsurface Drip Irrigation (SDI) is a management tool that helps you gain control of the root zone environment by delivering water and nutrients straight to the roots of each plant. It helps you maintain optimal soil moisture levels, uniformly across your field, with better aeration. The result is increased yields, reduced water needs, and runoff, better management of crop quality, and less fertilizer and labor cost.

Additionally, you can use digital control systems to monitor and optimize your yield as it’s growing, gaining data about every stage of the crop lifecycle.
