METHOD FOR APPLYING WORKING SOLUTION OF MINERAL AND ORGANIC FERTILIZERS DURING SPRINKLING IRRIGATION AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC B05B1/08 B05B1/28 A01C21/00 A01C23/00 

FIELD: agriculture.

SUBSTANCE: sprinkler with a rotary deflector for joint irrigation and fertilization, performing a rocking-rotary movement, supported by a stop, on the curved concave surface of the deflector facing the outlet, alternating depressions and protrusions are made, allowing uniform distribution of fertilizers with irrigation water or separated by segments of the field surface, while changing the direction of the sprinkler jet and applying fertilizers with irrigation water occurs due to a change in the position of the nozzle in the outlet in relation to the fixed deflector for irrigation: a) in a circle or in four directions separated into segments; b) of a 180° segment ; c) of a 90° segment; d) of a 270° segment. The method of applying the working solution of fertilizers when irrigating with a sprinkler with a rotary deflector.

EFFECT: inventions make it possible to reduce the technogenic load on the soil cover and increase soil productivity.
