What is polyacrylamide (PAM)?

PAM, or anionic Polyacrylamide, is a very long chain, high molecular weight organic polymer produced from natural gas, with characteristics which make it useful as a soil amendment to control runoff and soil loss.

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.

How do you apply polyacrylamide?

Totally mix and liquefy PAM mixtures prior to injection into the irrigation system. Inject only on the downstream side of all screens and filters. The maximum application rate of pure form polyacrylamide must not exceed 200 pounds per acre, per year. Ensure uniform application coverage to the target area, minimizing drift to nontarget areas.

How much polyacrylamide can I use per acre?

The maximum application rate of polyacrylamide active ingredient must not exceed 4 pounds per acre, per single application event. Totally mix and liquefy PAM mixtures prior to injection into the irrigation system. Inject only on the downstream side of all screens and filters.

How much polyacrylamide can be applied in irrigation water?

The resulting concentration of PAM in irrigation water must not exceed 10 parts per million of pure form polyacrylamide, applied on a total product basis. The maximum application rate of polyacrylamide active ingredient must not exceed 4 pounds per acre, per single application event.

Can polyacrylamide be used in lay-Flay polyethylene tubing?

Application of polyacrylamide (PAM) through lay-flay polyethylene tubing: effects on infiltration, erosion, N and P transport, and corn grain yield. MS Thesis, Mississippi State University. In review for Journal of Environmental Quality.
