A Texas AgriLife Research sub-surface irrigation study could reveal ways that will lead to higher crop yields and save water annually.
Tom Cothren, AgriLife Research crop physiologist and professor at Texas A&M University in the department of soil and crop sciences, is leading a project that uses a drip system to deliver water to plants rather than traditional furrow irrigation.
"Sub-surface irrigation reduces water loss from evaporation that occurs from above-ground applications and places water in the root zone where the crop can make most efficient use of its presence," Cothren said. "This system also eliminates runoff associated with furrow irrigation."
