Polyacrylamide in Agriculture and Environmental Land
Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation‐induced erosion and enhance infiltration. Its soil stabilizing and flocculating properties improve runoff water quality by reducing sediments, N, dissolved reactive phosphorus
The agricultural use of polyacrylamide, PAM, as an additive in irrigation water has grown rapidly since commercial introduction in 1995 because it improves water infiltration and reduces erosion
Polyacrylamide in Agriculture and Environmental Land
Its soil stabilizing and flocculating properties improve runoff water quality by reducing sediments, N, dissolved reactive phosphorus (DRP) and total P, chemical oxygen demand (COD), pesticides, weed seeds, and microorganisms in runoff.
Polyacrylamide (PAM), which is a hydrophilic polymer, has been used in the field of agriculture for nearly half a century due to its ability to increase infiltration and decrease irrigation
Polyacrylamide degradation and its implications
High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction
The environmental fate of a polyacrylamide thickening agent (PATA), formulated without and with a glyphosate-surfactant herbicide (GH), was examined under various environmental situations: formulation in surface water and ground water, volatility, and soil mobility.
Polyacrylamide Removes Microorganisms and Nutrients
Water soluble anionic polyacrylamide (PAM) was found to be a highly effective erosion-preventing and infiltration-enhancing polymer, when applied at rates of 1 to 10 gm-3in furrow irrigation water. Water flowing from PAM treated irrigation furrows show large reductions in sediment, nutrients and pesticides.
Polyacrylamide (PAM) treatment of irrigation water is a growing conservation technology in irrigated agriculture in recent years. There is a concern regarding the environmental impact of PAM after its application.

The use of anionic polyacrylamide (PAM) as a soil conditioner could help prevent soil loss by water. In this study, we determined the effective granular PAM rate that best reduces runoff and soil loss from Oxisols. Furthermore, the effectiveness of the selected PAM rate was tested by applying it in a mixture with gypsum (G) or lime (L). The study was conducted in two phases: (i) Dry PAM rates
Effect of Polyacrylamide Application on Water and Nutrient
duce better-quality agricultural products. The excessive use of fertilizers in agricultural settings has created nu-merous environmental problems, such as the degradation of soil quality, eutrophication, and the deterioration of the quality of surface water and groundwater [1].
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).Researchers wish to determine the fate of PAM, once added to furrow water streams.
