What is water soluble anionic polyacrylamide (PAM)?

Water soluble anionic polyacrylamide (PAM) was found to be a highly effective erosion-preventing and infiltration-enhancing polymer, when applied at rates of 1–10 g m −3 in furrow irrigation water. Water flowing from PAM treated irrigation furrows show large reductions in sediment, nutrients and pesticides.

Does dry granular Pam reduce runoff and erosion?

Surface application of dry granular PAM mixed with gypsum was effective in decreasing runoff and erosion. However, surface application of dry granular PAM without a source of electrolytes was not effective in maintaining a good infiltration rate (IR), but was effective in preventing erosion.

Does gypsum and dissolved polyacrylamide reduce runoff and erosion?

Surface application of dissolved polyacrylamide (PAM) mixed with gypsum was found to be effective in decreasing seal formation, runoff and erosion. Surface application of dry granular PAM mixed with gypsum was effective in decreasing runoff and erosion.

Does polyacrylamide reduce sediment in irrigation?

PAM, used following NRCS guidelines (Interim conservation practice standard—irrigation erosion control (polyacrylamide), 1995, Anionic polyacrylamide (PAM) erosion control (Acre)‐code 450 USDA‐NRCS, NHCP, 2001), reduced sediment in runoff 94% in 3 years of furrow irrigation studies in Idaho (Lentz and Sojka, 1994).

What is ionic polyacrylamide (PAM)?

Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation‐induced erosion and enhance infiltration.

Is polyacrylamide effective for erosion control and water quality protection?

Since the early 1990s use of polyacrylamide (PAM) has been shown to be an effective strategy for erosion control and water quality protection ( Lentz and Sojka, 1994 ).
