METHOD OF AGRICULTURAL CROP FOLIAR APPLICATION Russian patent published in 2014 - IPC B05B5/00 A01G25/16 A01C23/04 B05B7/04 B05B7/32 A01M7/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture. The method comprises spraying the agricultural crops with an initial crushing the solution flow of microelement fertilisers by the air flow and the subsequent drops electrocharge in corona electrostatic field. The liquid-air mixture is prepared at a distance from the hydraulic sprayer nozzles, then fed under pressure to hydraulic nozzles, at the output of which it is crushed and passes in the form of a torch with bubbles of air through the electrostatic field, where the mixture in the form of liquid-air drops is electrostatically charged, is additionally crushed thus increasing monodispersity, surface moisture of the fed plants, the number of free ions of nutrients of microellement fertilisers, which, precipitating on the surface of the agricultural crops, penetrate into the plant, improving its nutrition. The drop size, their crushing, monodispersity of drops and the amount of free ions is regulated by the pressure of microelement fertiliser solution from 0.2 to 0.3 MPa, the air pressure of 0.4 to 0.5 MPa, injected in the solution of fertilisers in the pumping mains, microelement fertiliser solution flow through one nozzle to 0.3 L/min, electrocharging of the sprayed liquid-air drops with the electrostatic voltage on the electrodes of 3 to 5 kV and a current of 10 mA.

EFFECT: method enables to increase the saturation of the solution mixture of fertiliser with air and to increase the monodispersity of the sprayed solution of microelement fertilisers.
