摘要：
FIELD: agriculture.SUBSTANCE: invention relates to the field of agriculture, mainly to the agricultural chemistry. The method comprises a leaf analysis on need in mineral elements by sampling of leaves, determining the response in the form of the difference of photochemical activity of the chloroplasts suspension from the middle sample of fresh leaves by adding to it of the diagnosed element at the concentration of 10-4-10-10 M and without adding the element. The need of the plant in nutrition elements is determined depending on the value of activity level of chloroplasts, calculated as the difference in optical density values of chloroplast suspension of the control sample of the leaves before and after the illumination by the light source. When the level of activity of chloroplasts having a negative value, the plants are treated with preparations containing in its composition free L-amino acids of vegetable origin, obtained by hydrolysis of the vegetable protein. At the level of activity of chloroplasts equal to 0-10 units, the plants are treated with growth stimulators containing the phytohormones in its composition. At the level of activity of chloroplasts equal to 11-70 units, the plants are treated with complex fertilizers containing in their composition macro- and micronutrients, and also chelated correctors together with preparations containing amino acids of vegetable origin for the chelating effect. At the level of activity of chloroplasts of more than 70 units the plants are treated with complex fertilizers containing in their composition macro- and micronutrients and chelated correctors. The subsequent determination of the values of the level of activity of chloroplasts and processing with the relevant nutrient is carried out after 10-14 days. The foliar plant processing can be carried out.EFFECT: method enables to increase the efficiency of diagnosis of need of plants in nutrition elements, prior to the onset of visual signs of stress and loss of produc
