solids (SS) were investigated in laboratory rainfall simulations in an effort to identify
conditions that could reduce erosion and improve water quality in farming districts. Small
runoff plots of 1× 1× 0.5 m in size were filled with loamy sand. Experimental treatments were
rice straw mat cover of 0 (control), 300, 600, and 900gm− 2; slopes of 10% and 20%; and
rainfall intensities of 30 and 60mm/h. Runoff volume from covered plots was significantly …
