  • Does dry granular Pam reduce runoff and erosion?
  • Surface application of dry granular PAM mixed with gypsum was effective in decreasing runoff and erosion. However, surface application of dry granular PAM without a source of electrolytes was not effective in maintaining a good infiltration rate (IR), but was effective in preventing erosion.
  • What is anionic polyacrylamide (PAM)?
  • Volume 224, article number 1382, ( 2013 ) Anionic polyacrylamide (PAM) is a linear, water-soluble anionic polymer that is widely used for erosion control and water quality protection.
  • Is polyacrylamide an organic nitrogen source for soil microorganisms?
  • Polyacrylamide as an organic nitrogen source for soil microorganisms with potential impact on inorganic soil nitrogen in agricultural soil. Soil Biology and Biochemistry, 30 (4), 1045–1052.
  • Does Pam application affect bacterial diversity and richness in agricultural soil?
  • We found that although soil receiving these massive PAM application rates and prolonged exposure may reduce active bacterial and fungal biomass, PAM application did not substantially or consistently affect bacterial structural diversity, richness, or evenness in this agricultural soil.
