BMP C126: Polyacrylamide (PAM) for Soil Erosion Protection - ...
Polyacrylamide (PAM) is used on construction sites to prevent soil erosion. Applying PAM to bare soil in advance of a rain event significantly reduces erosion and controls sediment in two ways. First, PAM increases the soil’s available pore volume, thus increasing infiltration through flocculation and reducing the quantity of stormwater runoff.

Polyacrylamide (PAM) soil amendments are increasingly used to remediate these degraded lands with the potential benefits on soil health and crop production. However, the scientific evidence of farm-scale use of one-time versus repeated application of PAM has not been reported.
Why is polyacrylamide used in rain-fed agriculture?
The increased infiltration results in less runoff and erosion as well as reduced water usage. Polyacrylamide is economical under certain conditions in rain-fed agriculture such as on soils used for high value crops as well as management of problem areas in a field. Polyacrylamide is effective in reducing runoff, erosion, and soil sealing.
What are the environmental benefits of polyacrylamide?
Environmental benefits include reduced soil loss, reduced pesticide and fertilizer runoff. This enhances both soil and water quality, both on site and off site. Polyacrylamide is an alternative to traditional erosion control practices.
