      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.
