  • Does polyacrylamide affect soil erosion?
  • Results prove that the surface runoff and the weight loss of soil decrease with the increase of polyacrylamide concentration. Soil erosion is sorely a challenge affecting the sustainability and productivity of agriculture, thus leading to economic loss (Pimentel et al. 1995 ).
  • Does polyacrylamide reduce runoff?
  • Polyacrylamide applied at 10 mg L −1 in furrow via lay-flat polyethylene tubing reduced cumulative runoff and improved infiltration rates on both the silt loam and silty clay loam textured soils. The PAM main effect was significant for both runoff and infiltration ( P = 0.0020).
  • Do polyacrylamides improve soil infiltration?
  • Polyacrylamides (PAMs), when applied as a soil amendment, purportedly improve soil infiltration, decrease erosion, and reduce offsite agrochemical transport. The effect of PAM on infiltration, eros...
