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 a source of zinc 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 a source of zinc. The process yields a fertilizer product containing micronutrients with superior elemental and granule size distribution without compromising handling or storage qualities.
