Erosion from furrow irrigated land is a serious problem in southern Idaho and several other areas. Polyacrylamide, a very long chain polymer, increases aggregate stability and flocculates suspended sediments. It thus can potentially reduce furrow sediment detachment and transport. Recirculating infiltrometer studies showed that 0.5 kg/ha/irrigation of polyacrylamide applied with the irrigation water can dramatically reduce furrow erosion.
