The dissertation focuses on issue of a post-harvest residues in the crop rotation. The paper describes methodology of setting up the experiment, measurements, collection and analysis of samples. Also available is a characteristics and climatic conditions of the experimental locality. The amount of post-harvest residues were followed up for 3 crops (winter wheat after alfalfa, winter wheat after maize and spring barley after sugar beet) for three variants of tillage and three sampling depths. From these selected the most post-harvest residues 24.98 t.ha-1, was left by winter wheat grown after alfalfa sown variant with direct seeding. The smallest amount of 13.02 t.ha-1 was measured for spring barley after method of minimization. Option of plowing for wheat after alfalfa and wheat after corn reached was measured by average of 17.5 t.ha-1. Average amount of underground biomass of all crops without distinction in processing variations was resulted at the depth of 0 - 0.15 m amount of 10.03 t.ha-1. At a depth of 0.15 to 0.30 m, it was 2.84 t.ha-1 and at a depth of 0.30 to 0.45 m - 2.40 t.ha-1. The total amount of post-harvest residues (underground biomass + straw stubble) Winter wheat was grown after alfalfa - 21.25 t.ha-1, winter wheat after corn - 18.77 t.ha-1 and spring barley after sugar beat - 13.45 t.ha-1. The results of dissertation showed a significant difference according the results listed in the literature sources. This could be due to the influence of the year, which was extremely profitable and may also be influenced by the selection of representative localities, because the sample taken represents only a small portion of the total area
