WSU researchers create gel to keep fields healthy during drought

Washington State University researchers have created a product that could help farmers keep their fields moist during a drought.

Led by Associate Professor Jinwen Zhang, the group created hydrogel pellets similar to the super absorbent material used in diapers. The main difference is what they're made of. While diapers rely on petrolium based gel, WSU researchers have created one out of soy protein.

The pellets swell to hold 250 times their weight in water, and because they are made of biodegradable agricultural material instead of chemicals they leave no residue behind when they disintegrate in the ground. In fact, the soy protein can actually act as a source of nitrogen to help plants grow.

A soy-based product would also lessen dependence on foreign oil imports, and boos the local economy since the U.S. Produces half of the world supply of soy beans.

Zhang has applied for a patent and is working with mOasis, Inc., a California-based company that produces other agricultural gels, to begin testing the product in fields.
