| Various organic and inorganic mulches are used for soil
conservation purposes, the effectiveness of which on soil
characteristics has not been comprehensively considered from different
aspects. The present study surveys the
efficiency of straw mulch, manure and TA-200 polyacrylamide with respective
rates of 500, 300 and 50 g m−2 in changing sediment
concentration and soil loss. The experiments were conducted for sandy-loam
soil taken from a summer rangeland,
the Alborz Mountains, northern Iran. The experiments were performed under laboratory conditions with
simulated rainfall intensities of 30, 50, 70 and 90 mm h−1 and a
slope of 30%. The results showed that the straw mulch decreased soil
erosion at rate of 45.60% compared to the control plots and
performed better than manure (8.98% reduction) and PAM (4.74%
reduction). The results showed that the maximum reduction in sediment
concentration and soil loss for all soil amendments occurred at the rainfall
intensity of 90 mm h−1 with the rates of 58.69 and 63.24% for straw
mulch, 14.65 and 13.14% for manure and 20.15 and 23.44% for TA-200. |
