Study and Agrotechnical Evaluation of Turbine Fertilizer Applicator,

Abstract

Many field tests and scientific studies of the AT-2A and ATD-2 fertilizer applicators in the USSR and Bulgaria have shown that these units do not meet fully the agrotechnical requirements. There is excessive longitudinal and lateral nonuniformity when applying mineral fertilizers. The application of moist mineral fertilizers is poor, the application rate either decreasing or terminating entirely; the inadequate fertilizer applicator hopper volume requires frequent stops for reloading, during extended operation the fertilizer leaks out between the spreader disk and the hopper. The objective of the present study is to develop a new and more advanced fertilizer applicator which is free of the drawbacks of the existing units.
