research project title: the influence of polyacrylamide

RESEARCH PROJECT TITLE: The influence of polyacrylamide

From 12 to 124 tons of soil per acre can be lost each year from typical surface irrigated fields in the PNW. Using polyacrylamide (PAM) in surface irrigation can reduce soil erosion from furrow-irrigated fields by 94% and increase infiltration by 15%. However, little is known how PAM may influence the movement of soil-applied herbicides.

Effects of Biosolids on Soil and Crop Quality

Thus, in addition to their effects on soil and crop N, biosolids could also affect soil and crop P levels, soil pH, soil organic matter content, and soil trace element concentrations. Objectives of biosolids management then include supplying sufficient nutrients for crop production while minimizing the potential for nutrient loss from the soil, and maintaining soil pH and organic matter levels in desired ranges.

Acrylamide in Drinking-water - WHO

Acrylamide is highly mobile in aqueous environments and readily leachable in soil. As it has a higher mobility and lower rate of degradation in sandy soils than in clay soils (Lande et al., 1979), it may contaminate groundwater. However, its behaviour in subsurface soil, where most grouting takes place, has not been studied.
