Abstract
AbstractSoils from six different regions of the State of Uttar Pradesh, India, were treated with 1% and 2% concentrations of castor oil and incubated for 15 days and 30 days time. The erosion coefficients of natural as well as treated soils were determined with a simple laboratory erosion apparatus. The castor oil was found to be highly effective in reducing soil erosion. It was more effective in light texture soils with reduction in erosion coefficients to the extent of 88 70. Heavy textured soils also registered good reduction in erosion coefficient, to the extent of 20 %. The castor oil was effective in both the concentrations and both the incubation periods. Similarly, it was effective at all the four slope levels viz. 1, 2, 4 and 8%. The castor oil has been found much superior than cellulose and protein as far as their capability to check soil erosion is concerned.
