Role of organic and mineral fertilizers in increasing the productivity of gray forest soils

This paper deals with effect of organic and mineral fertilizers of domestic production on the grain yield and quality of spring wheat, corn, soybeans cultivated on gray forest soils. When applying «Vitalist», «Oasis», «Dobrodiy» and «Humisol» readily hydrolyzable nitrogen content, mobile forms of phosphorus and potassium were higher than the control, crop yields increased significantly, product quality has improved, a protein content has increased in grain of specified crop, carbon dioxide has intensive stood out, and the impact on the functioning of soil biota was shown more actively, phytotoxicity of soil has decreased.
