This work was carried out in Dourados, Mato Grosso do Sul State, Brazil, in order to evaluate soil erosion and water loss in pasture and in no tillage agriculture in a pasture-agriculture integration system using a portable rainfall simulator. Four rainfall intensities (40, 60, 80 and 100 mm h-1) were studied, each consisting of a treatment arranged in an experimental design in randomized blocks with four replications. Accumulated average soil loss varied from 1.33 to 10.50 g m-2 and water loss varied from 1.34 x 10-3 to 34.64 x 10-3 m³ m-2. The largest soil and water losses occured in the largest rainfall intensities and the no-tillage system had the largest soil loss and the pasture the largest water loss.
