MACHINE FOR DIFFERENTIAL APPLICATION OF LIQUID MINERAL FERTILIZERS Russian patent published in 2004 - IPC

Abstract RU 2239303 C1

FIELD: agricultural engineering.

SUBSTANCE: in proposed machine ejector is series-connected with central static flow swirler which is connected with each of static flow swirlers installed in parallel at inlet of distributing manifolds. Static flow swirlers are made in form of screw insert with pitch not less than diameter of pipeline in which there are installed. Thanks to it provision is made for differential application of liquid mineral fertilizers within large range of metered-out amounts and higher quality of their distributing on each plot of field.

EFFECT: increased covering of expenditures of fertilizers and yield.
