Theoretical and Experimental Verification of Organic Granular Fertilizer Spreading

Due to the continuous creation of organic granular fertilizers new composition, there is a lack knowledge about their properties and influence norm on spreading efficiency. To increase efficiency use fertilizers, aims are properly choose most rational parameters fertilizer norms, considering characteristics fertilizer. determine this quickly with lower costs, various theoretical models computer programs used study dynamics spreading. The purpose work was perform experimental comparative studies dosage norms poultry manure During research, physical were determined, which have an impact quality Experimental carried out using two centrifugal spreaders same (Amazone ZA-M-1001 (spreading norm, 200 kg ha−1 400 ha−1; driving speed, 10 km h−1) ZA-M-1201 600 ha−1, 800 1000 5 h−1)). Before spread, measurements made flow rate spreadable through one bunker shutter. Fertilizer application simulations performed discrete element simulation program EDEM. Research has shown that studied at allows for future expansion limits research simulation. important directions would be spreader vanes’ shape, length, settings positions, standard commonly spreader, after making small modifications achieve could spread larger or drive faster during
