  • Can polyacrylamide soil amendments be used on a farm?
  • Polyacrylamide (PAM) soil amendments are increasingly used to remediate these degraded lands with the potential benefits on soil health and crop production. However, the scientific evidence of farm-scale use of one-time versus repeated application of PAM has not been reported.
  • Can polyacrylamide be used as a soil stabilizing agent?
  • This chapter considers the potential of polyacrylamide (PAM, a synthetic organic polymer), as a soilstabilizing agent. Addition of PAM to aggregates at the soil surface leads to their stabilization and to improved bonding between adjacent aggregates that, in turn, improves soil physical and hydraulic properties.
  • Does adding anionic polyacrylamide improve soil aggregation?
  • Adding anionic polyacrylamide (PAM) to soils stabilizes existing aggregates and improves bonding between and aggregation of soil particles. However, the dependence of PAM efficacy as an aggregate stabilizing agent with soils having different clay mineralogy has not been studied.
  • 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.
