Resumo

The practice of activities related to extensive livestock and anthropogenic actions promote degradation processes in pasture or crop areas, and studies are needed to support the environmental management of these areas. Some of the factors that characterize the soil and indicate its quality are, mainly, the organic matter content, water infiltration in the soil and soil loss. By analyzing these factors and the types of land uses, we can get an idea of the soil conditions and their needs. Thus, the objective of the study was to characterize the process of water infiltration, organic matter content and soil losses in different soil uses, so that it can serve as a subsidy for the management and planning of areas under cultivation or pasture.We perform tests under three soil use conditions, degraded pasture, recovered pasture and eucalyptus cultivation,using rainfall simulator and analysis of soil samples to determine the organic matter content. We observed that eucalyptus cultivation had the largest and most significant impact on the increase of water infiltration and on reduction of soil loss and we concluded that maintenance of organic matter in soilis a key to the soil conservation.
