SUSCEPTIBILITY TO WATER EROSION OF SOILS FROM THE MUNICIPALITY SALTO DO CÉU, SW MATO GROSSO STATE, BRAZIL - BRASIL

Resumo

The evaluation of the potential for soil erosion may assist in the identification and recovery of degraded areas. The aim of this study was to evaluate the potential for soil erosion in the municipality of Salto do Céu, seeking proper planning of land use. In this area, a geomorphologic and soil type subdivision were made. A map on erosion potential was generated, associating the soil maps with erosion potential classes. These classes and the topographic factor originated a map of susceptibility to erosion. The erosion potential map was obtained matching the erosion susceptibility map with the capacity of land use from the area under study. Conflicts arose from the maps of potential erosion and usability. 59.57% of Salto do Céu area consists of Ultisols. In this municipality, 23.41% of its area has very high erosion potential, 67.80% medium erosion potential and 8.79% low erosion potential. Areas with high potential are composed of Entisols and Ultisols (Nitisols). The sites with high potential for water erosion are being used inadequately. In almost the entire municipality there are conflicts among the current land use and the real capacity to support the actual use
