METHOD OF OPTIMISING NUTRITION OF FRUIT PLANTINGS OF INTENSIVE TYPE Russian patent published in 2016 - IPC A01C21/00 A01G17/00 

FIELD: agriculture.

SUBSTANCE: invention relates to fruit-growing and precision farming. In compliance with selections soil samples into perennial plantations is performed separately in places of local application of fertilisers under droppers directly at the point of contact of solution of nutrients and soil and beyond the focus of concentration of nutrient substances: at the distance of 50-60 cm from the dropper in the direction to the center of spacing. Estimation of parameters of soil fertility is carried out taking into account the background level of provisioning of soil nutrition elements and degree of both within nutrients by determining the degree of agrogenic differentiation of soil agrochemical properties in the zone of local fertilizing (SD) by formula $$SD=\frac{\left(a-b\right)}{b}\times 100\%,$$ where a is absolute value of parameter of soil in the area of localisation of mineral fertilisers, b is the same beyond the fertilized area, 100 - conversion factor in percentage terms. At that, when SD > 25 % there is a considerable change of soil properties which is taken into account for discriminatory application of mineral fertilizers.

EFFECT: method enables optimising the doses of fertilizers, discriminatory application of agrochemical agents and reducing anthropogenic load.
