Estimating Polyacrylamide Concentration in Irrigation Water

Abstract One practice used to control irrigation-induced erosion amends irrigation furrow inflows with water-soluble, anionic polyacrylamide (PAM) at low concentrations (0.25–10 mg L?1). Researcher...

Polyacrylamide (PAM) is an effective flocculent widely used to reduced soil erosion. We hypothesized PAM would reduce transport of sediment and nutrients in surface irrigation water flowing over soil. We measured nutrients in irrigation inflow and runoff water and total and extractable nutrients in sediment transported from agricultural fields.

CiteSeerX — Field results using polyacrylamide to manage

A moderate-charge-density anionic polyacrylamide (PAM), highly effective for controlling furrow sediment losses, was employed in the field trials. Treatment efficacy depended primarily on application rate, PAM concentration in irrigation water, duration of furrow exposure, and inflow rate.

Estimating Polyacrylamide Concentration in Irrigation Water

Small concentrations of a moderate-charge-density anionic polyacrylamide (PAM), dissolved in irrigation water has been used to nearly eliminate soil loss from irrigated furrows and has increased net infiltration (total inflow minus total outflow). This paper summarizes polymer-related field studies conducted on highly erodible Idaho silt loam

CiteSeerX — Acrylamide Monomer Leaching from Polyacrylamide

Water-soluble anionic polyacrylamide (WSPAM), which is used to reduce erosion in furrow irrigated fi elds and other agriculture applications, contains less than 0.05 % acrylamide monomer (AMD). Acrylamide monomer, a potent neurotoxicant and suspected carcinogen, is readily dissolved and transported in fl owing water.

R.E. Water soluble polyacrylamide (PAM) was recognized in the early 1990s as an environmentally safe and highly effective erosion-preventing and infiltration-enhancing chemical, when applied in very dilute concentrations in furrow irrigation water . The mode of action involves surface soil structure stabilization and maintenance of pore continuity.
