RESEARCH ON THE FERTILIZER SPREADING PROCESS BY SPREADING GRANULAR FERTILIZERS

Abstract

Applying the principles of precision agriculture, attention is given to different field properties and varying fertilization, spraying, and sowing rates. Fertilization not only increases the precision of fertilizer distribution but also impacts yield quantities. Improper and unevenly distributed fertilizers are a major cause of reduced yields, the spread of crop diseases, lower grain quality, and higher grain production costs. The aim of the study is to examine and compare the uniformity of the fertilizer spreading process when applying organic and mineral granular fertilizers. The fertilizers used were granular grain husks and mineral granular fertilizers. The fertilizers were spread using a Kuhn MDS 9.19 centrifugal spreader, with a working width of 14 m and a driving speed of 11 km/h. Fertilizer rates were 300 and 400 kg/ha. The results showed that the distribution of granular mineral fertilizers was uniform across the entire working width. The crosswise distribution of organic fertilizers was uneven on both sides of the spreader, as the physical properties of these fertilizers and the fertilization rate significantly affected the dynamics of fertilizer spreading on the soil surface compared to mineral fertilizers.
