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.

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 ).

Do polyacrylamides improve soil infiltration?

Polyacrylamides (PAMs), when applied as a soil amendment, purportedly improve soil infiltration, decrease erosion, and reduce offsite agrochemical transport. The effect of PAM on infiltration, eros…

Do polyacrylamides improve soil agrochemical transport?

Assigned to Associate Editor Sam Carrick. Polyacrylamides (PAMs), when applied as a soil amendment, purportedly improve soil infiltration, decrease erosion, and reduce offsite agrochemical transport.

Does polyacrylamide reduce runoff?

Polyacrylamide applied at 10 mg L −1 in furrow via lay-flat polyethylene tubing reduced cumulative runoff and improved infiltration rates on both the silt loam and silty clay loam textured soils. The PAM main effect was significant for both runoff and infiltration ( P = 0.0020).

What is polyacrylamide (PAM)?

Polyacrylamide (PAM) is a generic chemistry term, referring to a broad class of compounds. There are hundreds of specific PAM formulations that vary in polymer chain length and number and kinds of functional group substitutions. In some chain segments PAM amide functional groups are substituted with groups containing sodium ions or protons.
