pentair vessels – water treatment and purification in saudi arabia
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 soil nutrient loss at a slope of 5°.
The nutrient loss caused by soil erosion is the main reason for soil degradation and environmental pollution, and polyacrylamide (PAM) as a common soil amendment has a great influence on runoff
