A significant number of nutrients are taken out of the soil by the harvest and, if they are not returned, in a few years the soil loses its fertility to such an extent that cultivation of vegetable crops becomes a meaningless activity. Searching for the reasons leading to significant variability of normative nutrient removal by grain crops is the purpose of the work. The authors performed calculations, used the results of field experiments with barley. Methods of determining the doses of mineral fertilizers, the balance of humus and nutrients in the soil are presented. The issues of resource conservation, occupational safety and environmental problems in the use of fertilizers are outlined.
Key words: nutrient export / fertility / yield
