Potential Use of Polyacrylamide for Soil Erosion Control
product can act as a soil erosion controller, retaining water and aggregating soil particles. 4. Polyacrylamide (PAM) and its potential use in erosion control. Hydrogel polymer is the name given to long molecule chains constituted of repeating units that capture water molecules. This characteristic makes them excellent at soaking up water.

Polyacrylamide (PAM) for erosion control - NWISRL Publications
Erosion is one of the banes of agriculture; it just won't go away. Its curse has hunkered over tillers of the soil for thousands of years, stealing soil, nutrients and productivity. Soil erosion is highly detrimental, both on and off site. It has been blamed for the loss of peoples and the collapse of civilizations. Now, a technology that uses an off-the-shelf chemical flocculent provides a

2.1. Polyacrylamide use for erosion control. Soil stabilizing polymers were used to aid road and runway construction in World War II (Wilson and Crisp, 1975). Uses were adapted for agriculture in the early 1950s (Weeks and Colter, 1952). PAM and other conditioners improved plant growth by reducing soil physical problems by stabilizing

Use of synthetic organic polymers (PAM) as soil additives for soil erosion control started as early as the 1950s. A number of reviews have been published, discussing the role of organic polymers, and especially that of negatively charged (anionic) high molecular weight PAM in improving soil structure and physical properties ( Levy and Ben-Hur
