METHOD AND DEVICE FOR DIFFERENTIATED DOSING OF LIQUID ORGANIC FERTILIZERS Russian patent published in 2017 - IPC A01C23/00 

FIELD: agriculture.

SUBSTANCE: dose for applying fertilizers is determined, the supply of liquid organic fertilizers is carried out from the container 1 of the unit by the centrifugal pump 2 through the pressure pipeline 3 to the doser-dispenser through the throttling inserts 6. A map-task for differentiated application of fertilizers is prepared. The dose for applying fertilizers during the working stroke of the unit is changed in accordance with the map by separating the adjustable part from the pressure flow of liquid organic fertilizers, which is sent back to the unit container. The device for differentiated dosing of fertilizers includes the container 1 and the dispensing and distribution system consisting of the centrifugal pump 2, the pressure pipeline 3, the shutter 5, the stirring branch pipe 4, the throttling insert 6 in the pressure pipeline, and the dispenser 7 supplying liquid organic fertilizers to the pipelines of the working bodies 10. The stirring branch pipe 4 is equipped with an adjustable valve with the actuating mechanism 9.

EFFECT: use of the invention makes it possible to differentiate the application of liquid organic fertilizers, ensures the homogenization and the increase of the pump efficiency factor at low application rates.
