Abstract:
Tillage erosion causes the undesirable changes in the soil, mainly decreased of fertility and other functions of soil. The field experiment was aimed at measuring the influence of sloping field on the translocation of soil particles during seedbed preparation by Lemken Kompaktor seedbed combination. Sandy-loam Cambisol is on this field. Depth of soil tillage was 0.10 m, operating speed was 4.5 km h-1. To indicate the soil particles displacement limestone grit with the fraction size of 10–16 mm was used. The measurement results document that differences between movement of seedbed combination on the flat ground and upslope movement (angle of the slope 8.1°) are minimal in terms of displacement of soil particles. But the variant of downslope movement (angle of the slope 9.8°) showed statistically significantly higher values of translocation distances. The dependence of the translocation is in all cases described by an exponential function. The upslope movement of the machine for soil tillage cannot be understood as a full-value corrective measure to the incorrectly chosen direction of downslope movement.
