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.
