Displacement of soil particles by erosion can be seen as a major threat to the quali
ty
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). Limest
one 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.
