OPTIMIZATION OF FERTILIZER APPLICATION UNIFORMITY IN CAPACITY OF CULTIVATED SOIL BY COMBINED PLOWS
Keywords:
optimization, fertilizer, application, cultivated soil, combined plowAbstract
In today's stages of agriculture, they widely use combined cultivating units, while the main cultivation –
combined ploughsharing – racked working bodies with additional working bodies, systems, devices. At
the Podilskyi State Agricultural and Technical University construction of combined plow is proposed
which provides simultaneous fulfilment of deep plowing with ploughsharing – racked working bodies,
active layer crumbling and mineral fertilizing of active core, topsoil milling and mineral fertilizing. The
purpose of research is the choice of the basic technological parameters – rotor radius R, the rotation
frequency ω and influence of their values on the quality of soil crushing and preparation of plant residues
and fertilizers. In the work we used the method of mathematical modeling of the process of fertilizers
movement, soil cutting with the rotor knives that spins with regard to the vertical axis, limits of coil
sowing device rotation in order to ensure minimum and maximum standards of a fertilizers applying,
fertilizers supplying from coils and distribution of feed on the horizon, we considered analytical value
between parameters of ray blades knife holder – width, radius, angle setting to the horizon.
