  • Why is polyacrylamide used in irrigation for erosion control?
  • Polyacrylamide (PAM) use in irrigation for erosion control has increased water infiltration and reduced soil erosion. This has improved runoff water quality via lower concentrations of nitrogen, phosphorous, and pesticides, and decreased biological oxygen demand.
  • Does polyacrylamide reduce soil erosion?
  • Soils treated with polyacrylamide maintain their original physical state in water erosion conditions. By stabilization of clay mineral aggregates by polymer adsorption, the water infiltration rate improvement and soil erosion reduction are observed.
  • Does polyacrylamide reduce nutrient loss in surface irrigated crops?
  • Reduction of nutrient and pesticide loss through the application of polyacrylamide in surface irrigated crops. In: Sojka, R.E., Lentz, R.D. (Eds.), Managing Irrigation-Induced Erosion and Infiltration with Polyacrylamide.
  • Is polyacrylamide a good soil conditioner?
  • However, as these solutions are proposed, numerous doubts and opposing opinions are emerging. Polyacrylamide (PAM), also known as “soil conditioner”, “soil amendment” and “soil stabilizer” in soil science ( Gilda Dell'Ambrogio and Wong, 2019 ), is commonly used to modify the unfavorable and damaged characteristics of soil.
