Abstract
Diagnosis of mineral, primarily nitrogen, plant nutrition has long been a priority in agrochemical science and agricultural practice. To determine the requirements of crops in basic nutrients such as phosphorus and potassium, soil diagnostics (the determination of the mobile forms of these elements in soils) was widely used, on the basis of which the doses of the corresponding types and forms of fertilizers were calculated. Soil diagnostics were also used to identify the need for plants in nitrogen fertilizers, mainly in the presowing period or at the beginning of the active vegetation of crops.
