  • Is polyacrylamide an organic nitrogen source for soil microorganisms?
  • Kay-Shoemake, Jeanine L. and Watwood, Mary E. and Lentz, Rodrick D. and Sojka, Robert E. (1998) Polyacrylamide as an organic nitrogen source for soil microorganisms with potential effects on inorganic soil nitrogen in agricultural soil. Soil Biology & Biochemistry. 30 (8/9):1045-1052.
  • 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 ).
  • 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.
  • Does polyacrylamide treatment reduce soil erosion?
  • Furthermore, polyacrylamide treatments increased water-stable aggregates content by 32.3% to 59.1%, total porosity by 11.3% to 49.0%, infiltrative rate by 41.3% to 72.5%, and reduced soil erosion by 18.9% to 39.8% compared with the control group.
