      Soil porosity and poorly structured soils can be improved by using polyacrylamide to prevent soil erosion and loss of nutrients. The cohesion of the soil is increased so that less sediment is entrained by water runoff. The result is an average reduction of 95% in erosion. The porosity of the soil is conserved, maintaining good infiltration of the soil by water.

      The primary functions of polyacrylamide soil conditioners are to increase soil tilth, aeration, and porosity and reduce compaction, dustiness and water run-off. Secondary functions are to increase plant vigor, color, appearance, rooting depth and emergence of seeds while decreasing water requirements, diseases, erosion and maintenance expenses.
