While much of the nation’s crops withered under last year’s punishing drought, Michigan State University researchers dramatically increased corn and vegetable production on test farms using revolutionary new water-saving membranes.

The subsurface water retention technology process was developed by Alvin Smucker, MSU professor of soil biophysics and MSU AgBioResearch scientist. His invention uses contoured, engineered films, strategically placed at various depths below a plant’s root zone to retain soil water. Proper spacing also permits internal drainage during excess rainfall and provides space for root growth.

“This technology has the potential to change lives and regional landscapes domestically and internationally where highly permeable, sandy soils have prohibited the sustainable production of food,” Smucker said. “Water retention membranes reduce quantities of supplemental irrigation, protect potable groundwater supplies, and enable more efficient use and control of fertilizers and pesticides.”

The prototype can be used on a broad range of agricultural crops, as well as growing cellulosic biomass feedstock, plants grown specifically for fuel production, on marginal lands. SWRT-improved irrigated sands produced 145 percent more cucumbers than did the control fields without water-saving membranes. Researchers also dramatically improved irrigated corn production, increasing yields 174 percent.
