Resumen
El manejo, la topografía de la zona y el clima hace que el suelo que sustenta al olivar mediterráneo se
enfrente a la erosión, relacionada con la productividad y la degradación de servicios ecosistémicos. De ahí,
la importancia de la medición de la pérdida de suelo mediante la Ecuación Universal de la Pérdida de
Suelo (USLE) y su versión revisada (RUSLE). En este trabajo, se estudiaron 12 parcelas del municipio de
Estepa, cuya diferencia fue la presencia o ausencia de cubierta vegetal. A partir de la aplicación de la
USLE/RUSLE, se pudieron obtener diferencias significativas entre los dos tipos de manejo con una
reducción considerable de la erosión en parcelas con cubierta. A su vez, la huella erosiva calculada para
las mismas, indicó que las parcelas con menor producción y mayor pérdida de suelo tuvieron una mayor
huella erosiva que el resto.
The management, the topography of the area and the climate make the soil that supports the Mediterranean olive grove face erosion, related to productivity and the degradation of ecosystem services. Hence the importance of measuring soil loss using the Universal Soil Loss Equation (USLE) and its revised version (RUSLE). In this project, 12 plots from Estepa municipality were studied, whose difference was the presence or absence of vegetation cover. From the application of USLE / RUSLE, significant differences could be obtained between the two types of management with a considerable reduction in erosion in the covered plots. In turn, the soil footprint calculated for them indicated that the plots with lower production and greater soil loss had a greater soil footprint than the rest.
