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.

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.Download the SDI-E Brochure
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 NETBEAT 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.Download the SDI-E Guide
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.
A blend of dairy effluent and freshwater is applied directly to the roots as the water expands outward in all directions from the drippers.
By applying an effluent water freshwater mix directly to the root zone via SDI, evaporation is almost totally eliminated. No moisture on soil surface means less weed growth and less cultivation or herbicide sprays.
Coordinating timing of nutrient distribution with plant uptake can reduce the amount of nutrients applied. With drip, nutrients are applied directly to the roots becoming quickly available to the crop.
Typically, SDI gives the ability to reduce overall amount of nutrients being applied, because it is applied with better timing coordinated with plant
Approximately 70-90% fewer greenhouse gases are released, when dairy effluent water is applied through an SDI system.
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.
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.
Two pumps are required at the head of the filter station for blending of the effluent water and fresh water before filtration.
In order to maintain system performance, pressure gauges should be placed at key locations.
Electronically powered mixing valves isolate and regulate flow of the fresh/effluent water mix.
A small air compressor is recommended for flushing valves.
The EC/pH 4G unit displays and transmits to an NMC Controller allowing chemical injection to regulate EC and pH levels.
For reliable measurement of salinity in the fresh/effluent water mix.
Manifolds are used after control valves to supply the fresh/effluent water mix to the driplines. A manifold design incorporating friction loss is critical in distribution uniformity of the water mix.
The use of flush manifolds is required to properly flush the driplines and reduce the labor requirement at the same time.

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.
