  • What is an anionic polyacrylamide (PAM)?
  • The use of soil amendments, including anionic polyacrylamide (PAM), is one of many options for protecting soil resources. In most applications, anionic polyacrylamide (PAM) is often used as a soil amendment to manage infiltration, runoff and soil erosion ( Entry and Sojka, 2003, Lentz et al., 1998, Lentz et al., 2001, Sojka et al., 1998 ).
  • How can a water soluble anionic polyacrylamide (PAM) reduce soil erosion?
  • Application of water-soluble anionic polyacrylamide (PAM) to the soil. Reduce soil erosion by water or wind. Improve soil surface infiltration rate and minimize soil crusting to allow for uniform plant growth. Irrigated lands susceptible to irrigation-induced erosion where the sodium adsorption ratio (SAR) of irrigation water is less than 15.
  • Does polyacrylamide reduce soil erosion in furrow irrigation?
  • Research results indicated that PAM application decreased soil erosion in furrow irrigation significantly (Trout et al., 1995 ). Polyacrylamide treatments showed the greatest infiltration improvement and erosion reduction compared with the controls.
  • How effective is Pam for erosion control?
  • PAM used for erosion control is a large (12–15 Mg mol −1) water‐soluble (non‐cross‐linked) anionic molecule, containing <0.05% acrylamide monomer. In a series of field studies, PAM eliminated 80–99% (94% avg.) of sediment in runoff from furrow irrigation, with a 15–50% infiltration increase compared to controls on medium to fine‐textured soils.
