Efficacy of granular polyacrylamide on runoff, erosion and nitrogen loss at loess slope under rainfall simulation

The chemical control of runoff, sediment and nutrient losses is one of the main measures of soil and water conservation and ecological improvement. A simulation experiment was conducted to investigate the effects of polyacrylamide (PAM) application rates (0, 0.5, 1, 2 and 4 g/m 2 ), rainfall intensi...
