Linear anionic polyacrylamide as an effective post-fire
Weed free, recycled paper pellets containing polyacrylamide were found to be an effective Burn Area Emergency Rehabilitation treatment option on clay rich soils containing divalent cations (i.e., Ca 2+) within the soil matrix. This study showed aerial application of the granular polyacrylamide pellets resulted in an even distribution of the polymer-based product on the soil surface.
Granular anionic polyacrylamide (PAM) was tested to reduce post-fire soil erosion. • PAM increased runoff in the 1st storm due to changes in runoff and soil solution viscosities. • This effect was reversed after one drying cycle. • The application of PAM reduced soil loss in three consecutive storms. •
Linear anionic polyacrylamide as an effective post-fire
Through water activation, a blend of water-soluble linear anionic polyacrylamide copolymers are slowly released, which bind with the soil particles, structurally stabilizing the soil. When compared to agricultural straw, polyacrylamide results show improved revegetation, reduced soil hydrophobicity, and reduced soil erosion.

Using polyacrylamide to mitigate post-fire soil erosion
In this work, we tested granular anionic polyacrylamide (PAM) to reduce post-fire soil erosion, and the mechanisms by which this polymer modifies infiltration rate (IR), runoff and soil loss. Two...
increased overland flow and soil erosion. In this work, we tested granular anionic polyacrylamide (PAM) to reduce post-fire soil erosion, and the mechanisms by which this polymer modifies infiltration rate (IR), runoff and soil loss. Two contrasting soils affected by fire were exposed to three consecutive simulated rainstorms
Polyacrylamide: A Review of the Use, Effectiveness,
Polyacrylamide can be cost effective in rain-fed agriculture under certain management regimes such as on soils highly susceptible to crusting and breaking the cycle of crusting-low organic residue production- crusting. As a soil conditioner, PAM is another tool that can be used to manage our soil resources.
Anionic polyacrylamide (PAM) has been proven to be an effective chemical soil amendment for reducing erosion in arable lands and infrastructure projects, but few attempts have been made to use it as a post-fire mitigation measure. Moreover, the mechanisms by which PAM reduces soil erosion are not fully understood. In this study, we tested the use of 50 kg/ha granular PAM as a post-fire
The use of PAM -- a linear polyacrylamide for use
Water soluble anionic high-purity PAM is a safe environmentally friendly soil conditioner, that when delivered via irrigation, reduces erosion, prevents sediment and chemical and biological pollutants from entering runoff and greatly expands management options for all forms of irrigated agriculture because of its soil stabilizing effects and
Center-pivot irrigation systems often apply water at rates greater than the soil infiltration rate. Applying high molecular weight, water-soluble, anionic polyacrylamide (PAM) to the soil can improve infiltration and reduce soil erosion The objective of this study was to determine whether single and multiple PAM applications with sprinkler irrigation improved infiltration under field conditions.
