Abstract: Methods, systems, and apparatuses for coating a fertilizer material by contacting the material with a coating material and a solvent are disclosed herein. The coated material can be obtained by mechanically agitating the fertilizer material while contacting the fertilizer material with a coating material and a solvent. The coating material can be sprayed onto the fertilizer material during mechanical agitation. The coating process and apparatus can use a paddle mixer and can be configured to handle organic solvents used to carry the coating material.

Abstract: A fertilizer granule containing a core containing a plant nutrient; and a coat containing 55 wt. % to 90 wt. % of a poly butylene succinate adipate (PBSA), 10 wt. % to 45 wt. % of a second polymer selected from poly lactic acid (PLA), poly butylene succinate (PBS), or a combination or blend of PLA and PBS, and 0 wt. % to 30 wt. % of a wax based on the total weight of the coat, the coat forming a coating on an outer surface of the core and methods of making and using the fertilizer granule. Also a coating composition containing 55 wt. % to 90 wt. % of a PBSA and 10 wt. % to 45 wt. % of a second polymer selected from PLA, PBS, or a combination or a blend of PLA and PBS, and 0 wt. % to 30 wt. % of a wax.
