Abstract:

Displacement of soil particles by erosion can be seen as a major threat to the quality of agricultural land in the conditions of Czech Republic. While the effects of water and wind erosion have long been investigated and reported, the effect of soil tillage technology on soil particles translocation are relatively new area of agriculture research. Soil tillage may contribute to the undesirable translocation of soil particles towards lower-lying parts of fields especially on slopes. The effect of soil tillage implements on soil particle translocation has not been sufficiently explained yet. The object of this research was to assess the influence of PTO (power takeoff)-driven tillage machines on soil particle translocation during secondary tillage (soil preparation). Measurements to determine the displacement of soil particles were performed in location Nesperská Lhota in the Central Bohemia Region. Measurements were performed on a sandy loam cambisol after harvest winter cereals (winter wheat). To indicate displacement of soil particles was used grit of white limestone (size 10–16 mm). Limestone was put down into the trench with known position orthogonal to the direction of working operations. Subsequently were performed working operations in the specified sequence. Limestone particles were counted and weighed in each section. It was detected by measuring the different nature of displacement for each machine. Statistical significance of differences in the weight of translocated particles was evaluated for different type of machines.

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.
