Abstract: Until now, most tillage erosion experiments were conducted under controlled soil and operating conditions. However, soil condition, tillage depth, speed and direction generally show substantial within-field variation. In this study, a series of tillage experiments were set up to investigate the erosivity of tillage under normal operating conditions. The effect of a typical tillage sequence, including multiple mouldboard, chisel and harrow passes, on soil translocation and tillage erosion was studied during a period of 3 years. Soil translocation in excess of 10 m was observed while the average net translocation rates ranged between 0 and 0.9 m. The results suggest that the annual tillage transport coefficient, associated with mechanized agriculture, is in the order of 781 kg m(-1) yr(-1). The experimental results also show that the tillage transport coefficient of a sequence of tillage operations can be reasonably well predicted from information provided by the farmer and by summing the transport coefficients obtained from controlled, single pass experiments. However, a Monte Carlo simulation showed that a relatively high number of tillage operations are required to obtain accurate estimates of the tillage transport coefficients in multiple pass experiments.
