    • using polyacrylamide to reduce soil erosion

      Using Polyacrylamide to Reduce Soil Erosion

      There is no indication of any adverse impact on soil, plant or aquatic systems when anionic PAM is used to control soil erosion. Because PAM limits soil erosion, using it can prevent nonpoint source pollutants from leaving the field. Nonpoint source pollutants include the soil and contaminants that can be attached to the soil — nutrients, herbicides and pesticides. Conclusions. Polyacrylamide can control soil erosion that occurs with irrigation.
