Agricultural Uses
Granulation is a significant advance in fertilizer technology, and provides considerable advantage to both the manufacturer and the user.
Fertilizers in the form of granules are granular fertilizers. Granulation of fertilizers (or pelletization of fertilizem) is the process of converting powdered fertilizers or final slurry into granules, ranging from 1 to 5 mm in size, during fertilizer production. The average granular fertilizer product is in the form of particles of around 1.00 to 3.35 mm in diameter. The Association of American Plant Food Control (AAPFC) defines 'granular fertilizer' as a fertilizer of which 95 % or more is retained on a series of sieves within the range of 4.75 mm to 850pm openings. According to the European and Japanese definition of granular fertilizer, the granules are generally intherangeof2.0to4.0mmindiameter.
Granular fertilizers cake less because of their less surface area, and they are, therefore, more advantageous to use. They produce less dust, hence, have lower product losses
