Effect of Polyacrylamide Application on Water and Nutrient Movements in Soils - SCIRP
Polyacrylamide (PAM) is known as one of soil conditioner that functions to stabilize soil structure, increase infiltration, and reduce surface runoff. This study assesses the effects of PAM on the vertical movement of soil-water and major/minor
Aims Various anionic polyacrylamide polymers (PAMs) are frequently used to improve soil properties and reduce erosion. However, the effects of their application on plant growth remain unclear. Methods Aggregate-free loess with high water holding
ANIONIC POLYACRYLAMIDE (PAM) APPLICATION
Application of water-soluble anionic polyacrylamide (PAM) to meet a resource concern. PURPOSE This practice may be applied to achieve one or more of the following purposes: • Reduce soil erosion by water or wind. • Improve water quality. •
The anionic polyacrylamide is a popular soil flocculant, commonly used to prevent erosion of arable soils. On the other hand, polymeric macromolecules can increase the accumulation of various toxic substances, such as heavy metal ions (among
Polyacrylamide degradation and its implications in environmental systems | npj Clean Water
The hydrolyzed form of polyacrylamide (HPAM), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic PAM in oil and gas development as well as in soil conditioning. 1,9,12,21
