SOIL EROSION BY HAND TOOLS FOR SMALL-SCALE TILLAGE ON HILLSLOPES ASSESSED THROUGH THE UNIVERSAL SOIL LOSS EQUATION

The objective of this study was to evaluate and compare the erosion rates generated by two types hand tools for small-scale tillage on a hillslope, using experimental tests Universal Soil Loss Equation (USLE). evaluated were conventional hoe redesigned furrowing hoe. work conducted in 145 m2 plot with an average slope 45% Colombia. Three treatments evaluated: a) Zero no herbicide (control); b) plus herbicide; c) herbicide. Each treatment represented sedimentation plot, three repetitions blocks (lower, middle, upper parts each plot), according maximum gradient. Both high extremely differences up 8.1 times between them. accelerated soil rates, being higher tillage. USLE method showed methods, while found tests. This is explained lower sensitivity detect changes factors such as type, cover, slope.
