    Using Polyacrylamide (PAM) to Reduce Erosion on Construction

    PAM should not be applied alone for erosion control, but in combination with mulch and seeding. This is especially important on steeper slopes. There are many types of PAMs, each with slightly different properties and ability to react with a specific soil. Be sure to use the PAM that works best on the soil at your site.

    The Dirty Gardener Agritak PAM Polyacrylamide

    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
