      Polyacrylamide efficacy for reducing soil erosion and runoff

      Abstract. Polyacrylamide reduced SL for all slopes. A higher rate of PAM (40P) had less SL than a lower rate of PAM (20P) at slopes of 20% and 40%. With 40P, the reduction in SL was 72% greater than 0P at 40% slope. Therefore, slope is a critical factor in determining a PAM rate for reducing soil erosion and should be considered for proper application.

      Using Polyacrylamide to Reduce Soil Erosion

      High soil erosion rates occur either from furrow-irrigated fields with slopes greater than 3 percent or on soil prone to erosion. Although the rate of soil loss is greatest on fields with slopes greater than 3 percent, cumulative annual soil loss is greater on furrow-irrigated fields having 1-3 percent slopes, due to total acres involved.

      Benefits and Costs of Applying Polyacrylamide (PAM)

      Polyacrylamide is a synthetic water-soluble polymer made from monomers of acrylamide. PAM binds soil particles together. Once soil particles suspended in water are bound together by PAM, they settle out, so water has a harder time washing them out of the field. Water-soluble polymers like PAM have been known to benefit soil properties for a long time.
