METHOD AND DEVICE OF SIMULTANEOUS DIFFERENTIATED APPLICATION OF LOOSE AGROCHEMICALS AND SOWING Russian patent published in 2018 - IPC A01B79/02 A01C17/00 A01C5/08 

FIELD: agriculture.

SUBSTANCE: invention provides for forming optimal doses of agrochemicals, based on multispectral images, by which the parameters of mathematical models are clarified, the harvest amount and the content of mineral nutrition elements in the soil are estimated. The estimates are then compared with the optimum values, and the difference obtained is applied before sowing in each elementary section of the field, and the crops are sown according to the optimum sowing rates obtained. According to the number of volumetric dosers of agrochemicals, additional volume seed dispensers connected by seed lines to the agrochemical supply pipelines, as well as controlled rotary flaps, in front of which optical seed counters are installed in the seed lines, are introduced into the device. In addition, a unit for determining the optimal dosage of agrochemicals and sowing rates, as well as seed rate regulators, are introduced into the device.

EFFECT: increasing the yields of agricultural crops.
