Subsurface Drip Irrigation (SDI)

Why Drip and How Does It Work?

A quick bit of history...

As a farm family, we are always trying to maximize our efforts in the field.  How can we increase yield? How can we minimize expenses? How can we help the plants when we recognize they are in distress?

Enter, Drip Irrigation.

When researching which companies had the best drip irrigation product - we quickly concluded the answer is NETAFIM(tm).  

Once you identify the solution, you have to MOVE!

Within two weeks of learning about Netafim, we met with Netafim management, saw the system up close on a farm in Northern IL, and spent time discussing the equipment with growers actively using Netafim products.  Soon after, we joined the Netafim dealer network and began the installation process on our own family farm.

Who is Netafim?


"Since it's inception in 1965, Netafim has pioneered drip irrigation advancements to help growers increase yields and profits using less water. With billions of Netafim emitters already installed around the globe, Netafim is the worldwide leader in drip irrigation technology.  Netafim drip irrigation systems are good for grower profitability, good for the future of farming and good for water conservation."

How Drip Works.

"Subsurface drip irrigation (SDI) consists of flexible polyethylene tubing with emitters permanently welded to the inside wall of the tubing  The tubing system is buried within the soil in rows (typically 40" to 60" apart), at a depth (typically 12"-18" deep) suitable for the grower's purposes.

Water is pumped under low pressure from the source through a filtering system to the tubing  The emitters slowly emit specific amounts of water directly to the root zone of the plant.  The controlled, precise output of the emitter provides water at a rate that allows the plant to uptake most of the water pumped.  And, because the water is delivered underground, there is also no loss to evaporation, run-off or wind drift.

The system can also be used to deliver nutrients more efficiently.  The end result is improved yields with more efficient use of water. " -Netafim

"Basically, its an IV drip for crops and the grower controls when and what is delivered!"

Here's the Highlights


  • Water is delivered directly to the root zone.
  • No loss due to run-off, wind and almost no evaporation.
  • Water delivered consistently at rate of plant uptake.
  • Drip keeps soil well aerated.


  • Many growers see a minimum of 10% to 20% crop yield increase, and others much more.


  • Drip has very low labor costs compared to flood or center pivot.
  • Labor can be further reduced by automating the drip.


  • More efficient pumping (10 psi to 25 psi) reduces energy use.
  • System delivers nutrients more efficiently.
  • Dry surface reduces weed germination and disease problems.


  • Works on any size and shape with almost no waste.
  • Hilly ground is no problem with Netafim pressure compensating drip emitters.
  • Efficient option to make dry land more productive.


  • Higher yields and higher profits right away.
  • 4 to 6 year installation payback in most cases.
  • Some systems have paid back in two years.
  • Up to 25 years of long-term proven performance.

Subsurface Drip Irrigation Pays Off

We are so happy to have had the opporutnity to meet with Dan and learn about his operation in person.  

We're equally happy to be working with Kurt from Nurtadrip to bring subsurface irrigation to others in our farming community.

How Drip Is Installed

Introducing our Netafim Rep, Jim Ed Beach.  Jim Ed has been an amazing resource for Agrow Max, LLC as we source the best products and services for our community.  Check out how SDI is installed in this video.  Note, every field is a little different so set-ups vary.
