Title
(EN) Agricultural water retention and flow enhancement mixture
Abstract
(EN) Patent 502481 A technique is disclosed of applying selected chemicals for increasing agricultural water retention and minimizing erosion. The technique applies water absorbent polymers (10) into the top layer (15) of the field. These polymers create a water barrier within the soil. Subsequently, a linear polymer such as polyacrylamide is applied to the soil's surface to minimize erosion during irrigation and precipitation. The water absorbent polymers (10) assist in the thorough application of the linear polymer as the linear polymer is maintained at the surface area and prevented from leeching away.
