Effects of polyacrylamide on soil erosion and - ScienceDirect
aeration, reduce soil strength, and resist compaction, crusting, and surface sealing. Effects, such as increased infiltration and water retention, are often evident immediately on soil incorporation, whereas other effects, such as aggregation, depend on chemical and biological processes occurring over weeks or months.

Effects of Soil and Water Properties on Anionic - PubAg
Knowing the sorptive behavior of anionic polyacrylamide (PAM) by soils is useful in predicting the appropriate application rate, depth of effective treatment, and its mobility in soils. Sorption isotherms of PAM by soil materials, six natural soils, and their subsamples with partial organic matter (OM) removed by H₂O₂ oxidization under
