Soil translocation under pre-sowing operation performed with cultivator and harrow was analysed in the studies carried out on loess slopes of various inclination. Results showed that soil displacement was dependent on direction and velocity of tillage implementation, and slope inclination. Similar amount of soil was displaced, both down and up-slope, at slopes of 5-5.3%. Above this range, a net translocation of soil mass in down-slope direction prevailed. It's magnitude depended on slope inclination and temporal changes of velocity, being adjusted to configuration of short and concave slope. For the whole analysed slope on the average inclination of 7.3%, net soil displacement down-slope was 5.6 kg m⁻¹. Studies showed that tracers installed at soil depth of 0-15 cm were displaced furthest, on distances ranged from 27 to 62 cm. For these tracers, the translocation distance was strongly positively correlated with slope for down-slope, and negatively - for up-slope tillage.
