A semi-operational field trial that focused on Controlled Traffic Farming (CTF) was established in a ten hectare field. The experiment was established in Křinec in the Central Bohemia Region. The content of particles smaller than 0.01 mm – 38.3 %, soil type: loamy soil, the content Ct 3.12 %. The working width module was 6 meters. The experiment was conceived as a multiannual. The results of the experiment confirmed the benefit of concentration of machinery passes into permanent traffic lines in order to prevent adverse technogenic soil compaction. Apart from the beneficial effect on the soil physical characteristics and water infiltration capabilities, the concentration of passes into permanent traffic lines inflicted better work quality of soil tillage and sowing implements. Clod size and structure distribution, evenness of soil surface, degree of plant residue cover, distribution and incorporation of plant residues into soil profile can be ranked among the evaluation parameters of soil tillage quality. Within the evaluation of plant residue incorporation quality, the highest degree of plant residue incorporation into the soil profile was measured for the variant with zero passes (Variant 3), where almost 70 % of plant residues were incorporated. Within the variants with machinery passes present, the measured values were substantially lower, i.e. 26 % for Variant 1 and 17 % for Variant 2.
