      Using Polyacrylamide (PAM) to Reduce Erosion on

      Therefore, erosion control should always begin with protecting the soil from rain droplets and slowing overland flow by using mulch and vegetation. PAM does not directly protect soil from rain droplet impacts, but it reduces soil detachment, maintains the soil’s structure, and increases infiltration rates early in the rain event.

      G1866 Using Polyacrylamide to Reduce Soil Erosion

      Polyacrylamide (PAM) is one such measure. agent, binding soil particles together. It is harder for water to move these larger, heavier particles of soil. USDA researchers in Kimberley, Idaho began working with PAM in the early 1990s as a method to reduce erosion in furrow irrigation.

    • 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

      In papermaking, a microparticulate retention aid system consisting of bentonite and high molecular weight cationic polymer is commonly used to incorporate mineral pigments in the fiber web. It is believed that the mechanism by which bentonite operates is based on the ability of montmorillonite (its main component) to form a bridge between polymer-covered fibers and colloidal particles, resulting in heteroflocculation.
