Abstract


Depending on the amount allowable soil losses can be used to establishstrategies for choosing cultural structures and their relationship, their share in a crop rotation withvery good, good or poor soil protection. Following heavy rains, leaks occur as a rolled canvasspread over the land surface. Following leakage of these processes, with streams of water areentrained soil particles and moved longer distances or smaller. Following this process, after a time,depending on the frequency and duration of heavy rains that generate surface runoff, finally, lead tototal washing humus accumulation horizons and finally reach the parent rock or rock foundation.Under the indirect method (Equation universal erosion of the conditions in Romania) hasdetermined that the surfaces covered with forest, located on a slope of between 5-10% slope andslope length of steepest slope below 100 m, recorded an annual loss of 0.0067 t • ha-1, respectivelyon a slope with the largest slope length greater than 100 m is estimated annual quantity of 00.0058 t• ha-1.
