Excellent results are achieved adding only 10ppm PAM to irrigation water, applying 1–2kgha21 per irrigation, costing $4–$12kg21. Biopolymers are less effective. Using twice or higher concentrations, existing biopolymers are <60% effective as PAM, at 2–3 times

Polyacrylamide alone or 30 % surface cover alone produced similar results, both reducing cumulative runoff 10 to 20 % compared to untreated bare soil. Since runoff, erosion and phosphorus loss were reduced when PAM and surface residue were used individually and to a greater extent when used together, management choices should depend on overall

Polyacrylamide (PAM) use in irrigation for erosion control has increased water infiltration and reduced soil erosion. This has improved runoff water quality via lower concentrations of nitrogen, phosphorous, and pesticides, and decreased biological oxygen demand. Since non-toxic high molecular weight anionic PAMs removed clay size sediment particles in flowing water, we hypothesized that PAM

Wet aggregate stability following the first irrigation was greater in all PAM treatments than on the check. With 2 kg ha-1 PAM in the 20-mm irrigation, it was 55%; in 8 mm, 77%. Polyacrylamide applied in the first irrigation at low rates effectively reduced runoff and erosion. Erosion was more effectively controlled than runoff.
