The article presents an analysis of multi-year research on the development of the cultivation technology elements of the spring rape and winter cress, which provide an increase of oilseeds yield in the conditions of Ryazan Oblast. According to the experiment results, it was found that there was no significant difference in the biological activity of the soil in the crop rotation. The maximum yield of rape was observed in the option of the fallow link of crop rotation + mouldboard tillage – 31.3 dt/ha, and of winter cress – 25.6 dt/ha. In the research presented, the oil content of spring rape of the Ratnik variety was 43.4-47.6 %, of winter cress of the Lipchanka – 42.0-45.1 %. In addition, it did not depend on the cultivation intensity.

The experimental data of long-term researches establishing high efficiency of soil-protective system of agriculture with use of bioresources on biological and humus in condition of arable grey forest soil has been presented.
