| Sumario: | Agricultural production depends largely on the use of fertilizers. These are generally broadcast in solid form and their transport can affect its physical quality and therefore, its application, affecting use efficiency and crop yield. The purpose of this research was to evaluate the effect of two ways of transporting the fertilizer, screw and belt conveyor, on both the physical quality of the fertilizer and its application in the field. It was hypothesized that the screw conveyor system would affect the physical quality of urea and, consequently, its field application quality, in comparison to the belt conveyor. The work was carried out in September 2020, using urea fertilizer and two transport systems, a traditional screw conveyor and a belt conveyor. Fertilizer samples were taken before and after passing through the transport systems and the apparent density, granule size and hardness were evaluated. The transported fertilizer was applied with a double disc fertilizer and its field distribution evenness was evaluated. The screw transport system caused a decrease in bulk density and hardness of the fertilizer, resulting in a higher amount of fine particles (<2mm), which in turn affected its distribution in the field. Thus, compared to the belt conveyor, the screw transport system resulted in lower application quality, that is, higher coefficients of distribution rate variations, using the same fertilizer spreader configuration and spread width. The proposed hypothesis was not rejected. |
