  • Does polyacrylamide increase the rate of erosion?
  • Samples were subjected to artificial rainfall for 12 h after being placed at a 10° angle to increase the rate of erosion. Results prove that the surface runoff and the weight loss of soil decrease with the increase of polyacrylamide concentration.
  • 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...
  • 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).
  • 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.
