Abstract

An application of the MMP conceptual-empirical model is shown to evaluate quantitatively soil erosion in the karstic regions of the north slope of the Bejucal-Madruga-Coliseo Heights destined for grazing and located in Mayabeque province, Cuba. In specialized home literature there is no information available on this type of estimations. The model is based on the dynamics of the erosive processes, soil properties, climatic characteristics, relief conditions and the use of the edaphic cover. Slope values in the basins were indispensable for MMF application. This required the processing of the Digital Model of Elevations (DME) in the environment of a Geographical Information System that will allow obtaining the drainage net and the basins of interest. These latter were generated on considering as closing sectors some of the sampling points in which the soils were characterized. As result the drainage net and the generated basin maps are presented. For the first time the magnitudes of soil losses in slope environments are obtained. These heights are identified as the main source of sediments that sequentially descend to sectors of lower hypsometry. The estimated soil losses affect the productive capacity and soil fertility in cattle establishment.
Key words: slope karstification, slope erosion, erosion model. Rhodic ferralsol soils, Cuba
