Abstract

Тhe article presents the questions of the relevance of recycling organic matter and biogenic elements that enter the soil as a non-commodity part of the crop (by-products and root residues) depending on the yield of the main crop and crop rotation saturated with cereals, legumes and industrial crops.

The share of participation of each culture in the formation of articles of the balance of plant biomass has been established. It was revealed that the recycling of nutrients occurs due to the receipt of leaf-stem mass and roots of corn, the return of nutrients was from the total input in the soil of nitrogen 55, phosphorus 50 and potassium 46%.

The optimal crop rotation was calculated with 80% saturation with grain crops (including 20% corn for grain) and 20% technical (sunflower): biomass yield as well as its quantity returned to the soil with plant residues, including root crops 57%, while the share of the removed is the smallest among the studied crop rotations – 43%.
