Polyacrylamide in Agriculture and Environmental Land Management

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 -3 in furrow irrigation water. Water flowing from PAM treated irrigation furrows show large reductions in sediment, nutrients and pesticides.

How can a water soluble anionic polyacrylamide (PAM) reduce soil erosion?

Application of water-soluble anionic polyacrylamide (PAM) to the soil. Reduce soil erosion by water or wind. Improve soil surface infiltration rate and minimize soil crusting to allow for uniform plant growth. Irrigated lands susceptible to irrigation-induced erosion where the sodium adsorption ratio (SAR) of irrigation water is less than 15.

Can anionic polyacrylamide (PAM) be used to treat animal waste?

The application of anionic polyacrylamide (PAM) to soils and/or vegetative treatments may also provide a cost-effective way to dramatically reduce bacteria and nutrient loads in animal waste effluent and thereby reduce pollution in surface and ground waters receiving these effluents.

What is ionic polyacrylamide (PAM)?

Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation‐induced erosion and enhance infiltration.

Does polyacrylamide reduce soil erosion?

Polyacrylamide (PAM) is among the most common synthetic soil conditioners that can stabilize the soil surface by clumping fine soil particles, thus reducing irrigation-induced soil erosion [47, 48]. Many studies have shown that PAM decreases runoff and erosion rates while increasing infiltration and improving water retention . …

Is polyacrylamide a good soil conditioner?

Polyacrylamide has been the focus of a substantial amount of research in the 1990s. Our objective is to present a review of the recent findings and advancements in PAM work. As a soil conditioner PAM can be used to stabilize soil aggregates as well as flocculate suspended particles. Part of the attractiveness of PAM is its versatility.
