Analyzing the different quantitative evaluation direct and parametric methods to estimate the water erosion (USLE and the plots of field erosion) to determinate the soil loss in rural properties from Getulina and Vera Cruz counties, São Paulo state,Brazil

Abstract

The aim to do the abroad period at research group Calidad y Aplicaciones Suelos Medioambientales (CASAM), from Escuela Técnica Superior de Ingenieros Agronomists, Polytechnic University of Madrid, as described in the master regular research project (Process: 2014/02230-6), is to change knowledge about the estimation methods of soil loss by erosion, in particular: the Soil Loss Universal Equation (USLE) and the field erosion experimental plots, on the in order for them to be applied in determining the direct and indirect loss soils on farms studied in the research. So, will be emphasized the characteristics study of agricultural management systems that play a key role in determining the erosive response, the rainfall erosivity, soil erodibility and conservation practices.
