Soil erosion affects soil productivity and environmental quality. A laboratory research experiment under simulated heavy rainfall with tap water was conducted to investigate the effects of anionic polyacrylamide (PAM) application rates (0, 0.5, 1.0, and 2.0 g m −2) and molecular weights (12 and 18 Mg mol −1) on runoff, soil erosion, and …,Effect of Gypsum and Polyacrylamide Application on … ,Effect of Gypsum and Polyacrylamide Application on Erodibility of an Acid Kunigami Mahji … erodibility, gypsum, polyacrylamide.,Effect of polyacrylamide and gypsum on surface runoff … ,Hilly terrains with steep slopes and poor vegetative cover are prone to soil erosion. Crop productivity from such lands can be increased by adding correct amounts of soil conditioners such as polyacrylamide (PAM) and gypsum (G) to reduce soil erosion and to improve settling of suspended sediment.

Gypsum amended soil showed higher maximum sediment concentration. In terms of maximum sediment concentration, Fig.2 Effects of Polyacrylamide and Gypsum application on sediment concentration of Kunigami mahji soil.,Effects of polyacrylamide and gypsum on rainfall … ,Field experiments were performed for study of the effects of polyacrylamide(PAM),gypsum and their mixtures used in soil surface on runoff and sediment yield.The results show that PAM may help to decrease rainfall infiltration and soil erosion,while the utilization of gypsum leads to the increase of rainfall infiltration and decrease of soil erosion.It is also indicated that the mixture of PAM …,Effects of polyacrylamide on soil erosion and nutrient … ,PAM application influenced surface runoff and soil erosion, so it would impose certain effects on soil nutrient losses (Kay-Shoemake et al., 1998, Lentz et al., 1998, Oliver and Kookana, 2006). By furrow irrigation experimentation, Oliver and Kookana (2006) found out anion PAM application decreased N mass losses by 94%.
