Do polyaluminium chloride and anionic polyacrylamide water treatment residuals adsorb phosphorus?

Polyaluminium chloride and anionic polyacrylamide water treatment residuals (PAC-APAM WTRs) as an amendment in three types of soils with the ratios (w/w) of 10%, 15%, and 20% were evaluated for phosphorus adsorption from aqueous solutions by batch studies.

Can poly(dimethylammonium chloride) be used for erosion control?

There have also been a few reports of effective use of poly (diallyldimethylammonium chloride) (poly‐DADMAC) polymers for erosion control and improvement of soil physical properties (Bernas et al., 1995).

Does polyacrylamide reduce sediment in irrigation?

PAM, used following NRCS guidelines (Interim conservation practice standard—irrigation erosion control (polyacrylamide), 1995, Anionic polyacrylamide (PAM) erosion control (Acre)‐code 450 USDA‐NRCS, NHCP, 2001), reduced sediment in runoff 94% in 3 years of furrow irrigation studies in Idaho (Lentz and Sojka, 1994).

How does Pam affect soil properties?

It is also affected by soil properties, including the structural condition of the soil at the time PAM is applied as well as being affected by PAM formulation, molecular configuration, concentration, and application methodology (Lentz, 2003, Sojka et al., 1998a).

Does Pam reduce detachment and transport of soil particles?

Isolated reports hinted that very small amounts of PAM in irrigation water, flowing over soil in irrigation furrows, virtually eliminated detachment and transport of soil particles (Mitchell, 1986, Paganyas, 1975, Paganyas et al., 1972).

When did polymer soil amendments become popular?

Ironically, interest in the use of polymer soil amendments was first prompted by their use in road and runway construction during World War II (Wilson and Crisp, 1975).
