Impact of different treatments on soil loss from small watershed

Abstract

An investigation was carried out to study the effect of various treatments on runoff and soil loss from Model Watershed of Agro-Ecology and Environment Centre, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The data viz. Rainfall, runoff, soil loss and meteorology for 2002-14 was collected for four treatments viz., along the slope cultivation with opening of tied furrows (T1), contour cultivation with opening of alternative furrows (T2), contour cultivation with opening of furrows (T3), across the slope cultivation with opening of furrows (T4) undertaken at watershed. The runoff was found maximum for treatment T1 where as it was minimum for treatment T4. Treatment T3 and T4 were observed to be more effective in conserving the soil. Treatment T4 was found as the most effective treatment as there was no soil loss from study area during the year 2002 to 2014 while other treatments are contributing to the soil loss.
