Using Polyacrylamide (PAM) to Reduce Erosion

Overall considerations for using PAM to augment erosion control include: 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.

Various forms of PAM exist, but the type used for erosion control is a large, negatively (anionic) charged molecule (1215 megagrams per mole) that is water soluble. - Both cross-linked chained PAM and positively (cationic) charged PAM are not suitable for erosion control.

POLYACRYLAMIDE IN AGRICULTURE AND ENVIRONMENTAL LAND

Modified water management with PAM shows great promise for water conservation. High effectiveness and low cost of PAM for erosion control and infiltration management, coupled with easier implementation than traditional conservation measures, has resulted in rapid adoption. About 800,000 ha of US irrigated land use PAM for erosion and/or infiltra-

Since the early 1990s use of polyacrylamide (PAM) has been shown to be an effective strategy for erosion control and water quality protection (Lentz and Sojka, 1994). The application of anionic polyacrylamide (PAM) to soils and/or vegetative treatments may also provide a cost-effective way to dramatically reduce bacteria and nutrient loads in

All Applications . Only anionic polyacrylamide should be used for erosion control. The acrylamide should meet monomer limits of < 0.05%. The PAM should have a charge density of 10 to 55% by weight and have a molecular weight of 6 to 24 Mg/mole.
