Abstract
The performance of fertilizer spreaders during mechanized fertilizer application depends on their physical properties. Therefore, it is essential to understand the properties of any new fertilizer. This study aimed to determine the physical properties of AGROMENAS – G and NEREA fertilizers, which influence their mechanized application. The methodology used included determining the particle size distribution, bulk density, moisture content, and angle of repose of the material using well-known methods available in the scientific literature. The results showed that the NEREA zeolite-based fertilizer has a particle size distribution in which 72.61% of the material has particle sizes between 2 and 4 mm, that the bulk density of the material is 1120 kg m-3, the moisture content is 6.03%, and the angle of repose is 31.12°. AGROMENAS - G, on the other hand, has a particle size distribution where 56.6% of the material has particle sizes less than 1 mm, the bulk density is 1350 kg m-3, the moisture content is 6.06%, and the angle of repose is 29.34°.
