Polyacrylamide effects on infiltration in irrigated agriculture Rodrick Lentz Journal of Soil and Water Conservation Using polyacrylamide (PAM) following the NRCS conservation practice standard increases infiltration in furrow irrigation. PAM at 10 g in-' (10 ppm) during water advance nearly precludes detachment and transport of soil in furrows.

Polyacrylamide effects on infiltration in irrigated agriculture

Using polyacrylamide (PAM) following the NRCS conservation practice standard increases infiltration in furrow irrigation. PAM at 10 g m?3 (10 ppm) during water advance nearly precludes detachment and transport of soil in furrows. If any sediment is entrained in the flow, it is readily flocculated in the presence of PAM and settles to the furrow-bottom in loose pervious structures. It was

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 (DRP) and total P, chemical oxygen demand (COD), pesticides, weed seeds, and microorganisms in runoff.

Review of the Application of Polyacrylamides for Soil Erosion

Rates. PAM application rates per irrigation of about 1 kg ha-1 for furrow irrigation and about 4 kg ha-1 for sprinkler irrigation have been shown to be effective. Additional small applications of PAM may be necessary, if the ground has not been disturbed, on subsequent irrigations to maintain erosion and infiltration benefits.
