“…At other selected land slopes, the total runoff volume for 11 cm/h rainfall intensity was found 68670, 76650 and 82600 cm 3 ; for 13 cm/hr 99540, 98700 and 101570 cm 3 ; for 14.65 cm/hr 126070, 129150 and 130340 cm 3 at land slope 0%, 2% and 4% respectively. Figure 3-5 shows the measured runoff hydrograph at 0%, 2%, and 4% land slopes using simulated rainfall intensities (11,13,14.65 cm/hr) for 6, 8 and 10 ton/ha trash (sugarcane leaf) mulch. The mulching treatments were presented as percentages of deviation from the bare soil control.…”

Trash mulches are very effective in preventing soil erosion; reduce sediment transport rate, runoff rate and increasing infiltration. The study was carried out with the objectives to observe the sediment outflow from sugar cane leaf (trash) mulch treatments at selected land slopes under simulated rainfall conditions by using rainfall simulator of size 10 m × 1.2 m × 0.5 m with the locally available soil material collected from Pantnagar. In the present study, trash mulches with different quantities were selected to observe the effect of mulching in soil loss reduction. The quantity of mulch was taken as, 6 t/ha, 8 t/ha and 10 t/ha, three rainfall intensities viz. 11cm/h, 13cm/h and 14.65cm/h at 0%, 2% and 4% land slopes were selected. The duration of rainfall was fixed (10 minutes) for every mulch treatment. The total runoff volume was found to be varying with different mulch rates for particular rainfall input and land slope. The runoff distribution pattern was observed to be increasing with the increase in land slope. The average sediment concentration (SC) and outflow was found to be increasing with the increasing land slope, but SC and outflow decreased with increasing mulch rate for particular land slope and rainfall intensity. The SOR (SOR) for no mulch treated land was higher as compared to trash mulch treated lands. Mathematical relationships were developed for relating SOR, SC, land slope and rainfall intensity for a particular mulch treatment. It was observed that values of SOR and average SC had a good correlation with rainfall intensity and land slope for each mulch treatment. The correlation coefficients of developed models were found to be more than 90%.

“…In the 2016 FAO reports, 75 billion tons of soil are transported every year by erosion from arable lands throughout the world, which equals 400 billion dollars every year [13]. In India, the problem of soil erosion is quite serious as about 18.5% of the world total soil erosion occurs here [14]. India loses about 16.4 t of soil/ha/yr.…”
