Soil erosion is considered one of the biggest environmental problems worldwide. Water erosion acts most strongly in the degradation of agricultural soils, whose management can influence soil and water losses. Accounting for erosion losses and understanding the determining factors in the process enable the design of agricultural practices that promote the conservation of soil resources. The objective of this study was to evaluate soil and water losses under different conditions of rainfall intensity and soil management under simulated rain in a Yellow Red Latosol. The experiment was conducted in experimental plots 3.5 m wide and 11 m long, with 2 treatments and 3 replications under simulated rain. The treatments used were soil without tillage and soil with conventional tillage. Three successive showers were applied 24 hours apart, with intensities of 30 mm.h-1, 30 mm.h-1 and 70 mm.h-1. The runoff was collected at the end of each rain, having its volume and sediment concentration determined in the laboratory. The results showed that the different managements influenced the soil losses, with the largest losses in unmanaged soil. The higher rainfall intensity led to higher water losses in both tillage and conventional tillage. Runoff determines soil losses to some extent, from which other variables, such as vegetation cover, most strongly influence water erosion losses. |
