IMPACT OF TWO NATURAL RAINFALL EVENTS IN EROSION OF SOIL, WATER AND NUTRIENTS IN A NEGLECTED WASTELAND

Swati Sinha and M.P. Singh

Abstract

Present investigation has been carried out at two selected sites (I & II) in a neglected wasteland, Iaunpur (U.I’.) to see the impact of erosion on soil, water and nutrients in two natural rainfall events, i.e. 15 and 12 mm on two different days during rainy season. The vegetated plot showed lower values of soil erosion, Water and nutrient loss and high infiltration rate in comparison to bare plot at both the sites (I & I1). It was observed that the loss of soil, water and nutrients (N and P) were more at site I in comparison to site II. The annual soil loss in total rainfall (1346.8 mm) of the year during study period (2008) was 2.32 (veg-etated) and 27.18 t/ ha / yr (bare) plots at site I. In contrast, values were 2.04 (vegetated) and 25.95 t/ ha/ yr (bare) plots at site II.
