  • Can polyacrylamide reduce furrow irrigation erosion?
  • Reducing furrow irrigation erosion with polyacrylamide (PAM). J. Prod. Agric. 10, 1-2, 47-52. Sojka, R. E., and Surapaneni, A. (2000). Potential use of polyacrylamide (PAM) in Australian agriculture to improve off- and on-site environmental impacts and infiltration management.
  • Can polyacrylamide reduce irrigation run-off?
  • Research studies conducted since 2003 on the Central Coast have repeatedly demonstrated that polyacrylamide (PAM), a chemical polymer can significantly reduce sediment, nutrient, and pesticide concentrations in irrigation run-off from sprinkler and furrow systems.
  • Does polyacrylamide affect infiltration in irrigated agriculture?
  • Polyacrylamide effects on infiltration in irrigated agriculture. J. Soil Water Conserv. 53, 325-331. Sojka, R. E., Lentz, R. D., and Westermann, D. T. (1998b). Water and erosion manage- ment with multiple applications of polyacrylamide in furrow irrigation.
  • Does Pam reduce runoff from furrow irrigation?
  • In a series of field studies, PAM eliminated 80–99% (94% avg.) of sediment in runoff from furrow irrigation, with a 15–50% infiltration increase compared to controls on medium to fine‐textured soils. Similar but less dramatic results occur with sprinkler irrigation. In sandy soils infiltration is often unchanged by PAM or can be slightly reduced.
