Abstract
A granular cohered MOP fertilizer having one or more micronutrients, and one or more binding ingredients. The fertilizer is prepared by compacting MOP feed material with one or more micronutrients and one or more optional binders to form a cohered MOP composition. The cohered MOP composition is then further processed, such as by crushing and sizing, to form a cohered granular MOP product containing micronutrients. The process yields a fertilizer product containing micronutrients with superior elemental and granule size distribution without comprising handling or storage qualities.
