What is ionic polyacrylamide (PAM)?

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

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).

Can polymers reduce sand erosion?

That said, polymers have been successfully used to control dust at construction sites, reduce wind erosion of sand in arid and semiarid areas such as the Middle East, and improve slope stability , , , .

Does Pam reduce hydraulic conductivity in sand?

They concluded that PAM reduced saturated hydraulic conductivity (40–98 %) in sand but the reductions were less in loamy sand (0–56 %). A study by Malik and Letey (1992) investigated the effect of adding PAM solutions of various concentrations (25−400 mg/L) on the hydraulic conductivity of fine and coarse sands.

Does Pam affect soil aggregate stability?

The effects of PAM on soil aggregate stability under the two different molecular weights of PAM at different concentration are shown in Fig. 1. These results showed that treatment with PAM increased the aggregate stability of the treated sandy loam samples when compared to the control (untreated samples).

What are the adsorption properties of Pam polymers?

The polymer’s adsorption properties in dependence on the following parameters solution pH (in the range 3–9), temperature (in the range 15–35 °C), and carboxyl groups’ content in the PAM chains (in the range 5–30 %) were examined. The turbidimetry method was applied for determination of the suspension stability of alumina in the presence of PAM.
