Biologization technologies in agriculture of the Belgorod region

Abstract

The article summarizes the results of field experiments to study the effectiveness of biologization elements in the cultivation of agricultural crops in the Central Black Earth zone of Russia. It has been proved that compost based on poultry manure and granular organic fertilizers with shallow introduction contribute to an increase in yield of up to 50 cwt/ha of grain while improving the fertility of typical chernozem. The coefficient of structure is growing, the bulk density of the soil, physical and chemical characteristics are stabilized. Liquid pig-breeding drainage shows an increase in grain yield but does not have a significant effect on the state of arable land. Similar characteristics apply to technologies for the grain crops cultivation with the use of mineral fertilizers. The greatest economic efficiency was obtained with the combined application of different types of organic fertilizers in moderate doses with the surface method of the main soil cultivation.
