    Polyacrylamide (PAM) for Temporary Soil Stabilization CODE 893 893 - 1 DEFINITION The land application of a water soluble anionic or nonionic Polyacrylamide (PAM) as a temporary agent to bind soil particles and reduce erosion. PURPOSE The purpose of this practice is to temporarily stabilize disturbed soils and reduce erosion from wind and water

    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.

    Two polyacrylamide (PAM) compounds in which the NH2 was substituted with OH at 2% (2J) and 21% (21J), rendering them negatively charged, were used. Additionally, a guar compound (4246) used in the study was negatively charged and had a lower molecular weight than PAM. The soil was used without pretreatment and also with

    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

    The surface elevation of eroding sites decreases while that of aggrading sites increases under significant tillage erosion. Soil denudation rates due to chisel plow can be as high as 3.6–5.9 mm yr−1 for up- and downslope tillage and up to 1.5–2.6 mm yr−1 for contour tillage in soils on 20% slope gradient (Poesen et al., 1997).
