Object of research - agrochemical properties of typical low-humus chernozem, peculiarities of crop yield formation. Methods of research - field experiment, laboratory, analytical, mathematical and statistical, comparative and calculation. The results of the study - in the conditions of the Left-Bank Forest-Steppe, it was found that the effective formation of the soil nutrient regime under intensive farming is significantly facilitated by the main tillage (ploughing) of chernozem soil and uniform placement of by-products of the predecessor in the cultivated layer, which increases the content of mobile forms of nitrogen, phosphorus and potassium in both arable and subsoil layers of soil, contributes to the formation of positive values in the balance of these nutrients and additional accumulation of moisture. The maximum humus content in typical chernozem was achieved by classical ploughing and application of N60P60K60 + by-products of the predecessor: in the 0-20 cm layer - 3.88%, in the 20-40 cm layer - 3.16%, exceeding the control without fertilisers by 16-22%, respectively. Shallow disc cultivation and No-till technology in combination with N60P60K60 mineral fertiliser increased the humus content by 8-12% and 9-14%, respectively. The increase in crop productivity in short-rotation crop rotations, depending on the tillage technology, was 1.1-1.8 t/ha. Product Description popup.authors Zadubynna Yelyzaveta V.
