Resumen
LOZANO-GARCIA, Beatriz y PARRAS-ALCANTARA, Luis. Present and potential erosion in acid soils in the south Spain. Terra Latinoam [online]. 2011, vol.29, n.1, pp.35-46. ISSN 2395-8030.
This study determined the values of present and potential water erosion of soils in the Natural Park of Cardeña and Montoro, as well as the weight of each one of the potential factors in the calculation of total potential erosion. The aims were to determine the current situation in this natural area relative to the problem of erosion, so common in Mediterranean areas, and to observe how erosion changes when conditions (and, hence, erosion factors: soil susceptibility to erosion, soil vegetation, and soil conservation practices, individually or combined) change. It was verified that present rates of soil loss in the zone are not high: 93.2% of this natural park has erosion levels of less than 25 Mg ha-1. In the case of an unfavorable potential situation, however, soil losses would be important: 60.3% of this area would have erosion level higher than 25 Mg ha-1. Potential plant cover, of the three potential factors, is the factor that contributes most to the total. All the data were treated by SIG allowing the manager to update the data in real time when performing in the study area.
