                         acceleration of the erosive process and alteration on the soil 
                         characteristics. To explore the effects of human disturbance, we 
                         investigated the influences of natural and anthropogenic features 
                         on soil quality and soil erosion indicators (EI) within a 
                         Brazilian rural watershed located in Bauru Municipality, State of 
                         Sao Paulo. A pre-established set of soil EI was used to evaluate 
                         the influence of anthropogenic land cover categories on the 
                         presence and severity of erosion, related with spatial variations 
                         of soil attributes. On-site visits were carried out to measure the 
                         occurrence and the intensity of eleven separate EI values and to 
                         collect undisturbed topsoil samples for subsequent analyses. We 
                         registered 17 occurrences of EIs, distributed in ten locals. 
                         Occurrence and intensity of EIs were related to degree of sheet 
                         erosion. The EI qualities were more strongly associated with land 
                         cover management practices than to local topographic features. The 
                         occurrence of EIs and characteristics of soil and soil organic 
                         matter (SOM) were not significantly self-correlated. Although land 
                         cover class seems to influence soil properties and SOM attributes, 
                         we observed that the granulometric composition of the soils also 
                         contributes to the structural characteristics of the soil and 
                         consequently to the dynamic loss and gain of soil carbon. Sites 
                         covered with natural remnant vegetation (NRV) store 96.5 Mg ha-1 
                         of C and grassy and tilled soils stored more C than NRV, 100.1 and 
                         142.4 Mg ha-1 , respectively. Due to the influence of soil texture 
                         over the soil C dynamic, we observe that in Bauru, pastured areas 
                         have high potential for sequestration of C if factors such as fire 
                         and/or erosion were avoided or effectively controlled. Results 
                         from this study show that human disturbance substantially affects 
                         soil properties within of southeastern region of Brazil.",
