摘要： Magnesium oxide, urease inhibitor, and superphosphate coated urea-based fertilizer core, methods for their use, and production thereof, are disclosed. The coating can be a powder coating containing particles that are 1 micron to 100 microns in average mean diameter. The fertilizer core, coated by the magnesium oxide, urease inhibitor, and superphosphate coating, can contain 50 wt. % or more, based on the total weight of the core, of a urea-based fertilizer, such as urea. The coating can optionally contain or exclude anticaking agent(s), and/or binding agent(s).

摘要： A fertilizer blend containing 10 wt. % to 90 wt. % of a first particulate fertilizer composition and 10 wt. % to 90 wt. % of a second particulate fertilizer composition is disclosed. In the fertilizer blend, the second particulate fertilizer composition can be blended with the first particulate fertilizer composition. The first particulate fertilizer composition can include a core containing a binder, a pH buffering agent, and an urease inhibitor, and a shell containing urea, where the shell covers at least a portion of an outer surface of the core.
