Control with anionic polyacrylamide of runoff and erosion

Since 1997, studies of anionic polyacrylamide (PAM) application have been conducted on field experiments, under surface irrigation and on contour and slopping furrows, and also with pressurized irrigation (center pivot and sprinkler simulators), as well as in more controlled laboratory studies, to test the PAM usefulness in controlling erosion

ANIONIC POLYACRYLAMIDE (PAM) APPLICATION

CODE 450 (ac) DEFINITION Application of water-soluble anionic polyacrylamide (PAM) to the soil. PURPOSE This practice is used to accomplish one or more of the following purposes: Reduce soil erosion by water or wind. Improve soil surface infiltration rate and minimize soil crusting to allow for uniform plant growth.

Effects of polyacrylamide on soil erosion and - ScienceDirect

For reducing SL, a high level of PAM had better performance at a steep slope compared to a low level of PAM or [less than or equal to] 40% slope. Generally, the applications of PAM amendment were not effective in reducing RO, but increased TRO. Differing amendment performance for different soils and slopes make it necessary to continue to

Anionic polyacrylamide has been shownto be the most effective type at reducing sealformation and maintaining high infiltrationrates (Shainberg and Levy, 1994), and it alsohas a longer temporal effect than cationicPAM (Levy et al., 1992). Anionic PAM alsoposes little danger to off-site water organ-isms,unlike cationic PAM.

The action decreases runoff and erosion. The action increases infiltration. Because irrigation-induced erosion is reduced, there is less delivery of sediment-attached nutrients to be carried off-site to surface water. The action increases infiltration.

Field experiments were conducted to test the influence of two types of anionic polyacrylamide (PAM) on soil erosion and runoff of sloping land in Jordan under natural rainfall conditions. The two PAMs used in this study, Superfloc A-836 and Superfloc A-870, varied widely in molecular weight ranging qualitatively from high, 15 Mg/mol, to very
