Mathematical models of renoff and soil loss rates from base soil (fallow) on calcaric chernozem, obtained by simulated rainfall are presented in the paper. Simulated rainfalls were carried out at three slope gradients (14, 7.5 and 4%), at four rainfall intensities (2.0; 1.0; 0.5 and 0.3 mm/min). Three consistent rainfalls were carried out at the same intensity (first interval of 24 h and second of 1 h) of each runoff plot (8/1.5 m). The quantity of all simulated rainfalls is 50 l/m2.
