  • Do polyacrylamides improve soil agrochemical transport?
  • Assigned to Associate Editor Sam Carrick. Polyacrylamides (PAMs), when applied as a soil amendment, purportedly improve soil infiltration, decrease erosion, and reduce offsite agrochemical transport.
  • 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 increase grain yield?
  • Similarly, Lentz and Sojka (2009) reported that anionic EC PAM applied at 10 mg L −1 in furrow to a silt loam textured soil increased soybean [ Glycine max (L.) Merr.] yield by 14.3% and corn yield by 4.5% relative to a water-only control. Polyacrylamide effects on grain yield are possibly attributed to two processes.
