Abstract
The main purpose of man's activities in crop production is to provide such a final product which will, by its quality and quantity, meet the basic principles of cost-effective and cost-efficient production. High yields are leaving soli with the lower productivity and with much worse physical and mechanical properties. In this sense, application of fertilizers is of a great importance. The aim of this study was to demonstrate how much the uniformity of distribution depends of the applied fertilizers physical-mechanical properties and technical system of application. The paper gives the results of two centrifugal spreaders working quality in relation to physical and mechanical properties of applied fertilizers. Variation coefficients showed that no good uniformity was achieved. Real application varied significantly along the swath having the oscillations from 82% lower to 56% higher than the nominal application rate.
Keywords:
