METHOD AND DEVICE FOR DIFFERENTIATED SOWING APPLICATION OF BASIC AND STARTING DOSES OF MINERAL FERTILISERS Russian patent published in 2012 - IPC A01C21/00 

FIELD: agriculture.

SUBSTANCE: invention relates to crop production, in particular intrasoil fertilisation simultaneously with sowing. In the method of differentiated sowing application of mineral fertilisers the basic and starting doses of fertilisers are applied simultaneously with sowing and together with seeds for 4-10 cm deeper than seeding-down. Before sowing, the information is obtained about the parameters of fertility of the field in the system of global coordinates. Then an electronic map of a rational need in elements of nutrition of the cultivated crop for obtaining the optimum yield is made. The required dose of mineral fertilisers application per each elementary area of the field is established. The data from the map are sent to the microprocessor that controls the operation of metering unit of mineral fertilisers. The amount of fertilisers sown, designed for each elementary area of the field, is distributed to the start and the basic dose. The device for differentiated sowing application of the basic and the starting doses of mineral fertilisers comprises a hopper for seeds and a hopper for fertilisers, seed metre, highly adaptive metering unit of fertilisers, pneumatic system of sowing seeds and fertilisers. The device is equipped with a positioning system GLONASS/GPS.

EFFECT: sound management of productional process, increase in payback and efficiency of mineral fertilisers.
