Sažetak
Total quantity of erosional drift was measured on Stagnic Luvisol under six tillage methods in five years of investigation. The paper presents the results on the texture of tilled soil in particular trial methods and in erosional drift from the same plots. The results obtained point to the conclusion that erosional drift was generally richer in silt and clay particles. According to the standard deviation, approximately the same quantity of coarse sand was recorded in plot soil and in erosional drift in all tillage methods. As regards the content of fine sand, sometimes more and sometimes less of such particles were found in erosional drift than in plot soil. In most cases, more silt particles were determined in erosional drift than in plot soil. Standard deviation and the coefficient of variation for clay and silt are in all methods higher in erosional drift than in plot soil. The highest content of clay particles was recorded in erosional drift from no-tillage treatment in all investigation years. Investigation results show that an adequate choice of the tillage method (no-tillage and ploughing across the slope) on Stagnic Luvisol may efficiently protect the soils on the slope.
