This invention relates to an improved urea-nitrogen stabilizer composition and methods, systems and apparatti for making thereof. The nitrogen stabilizer composition is incorporated into molten urea to result in a composition that contains less biuret, NMP, nitrogen stabilizer and/or impurities and provides an effective solid fertilizer. These compositions are useful in in odor control.

The present disclosure relates to a method for controlling the temperature in a granulator in which a melt of an hydrous nitrate mineral salt-based composition is granulated. The method comprises the steps of granulating the melt, separating out the undersized and oversized particles at the outlet of the granulator and recycling the undersized and oversized particles to the granulator, measuring the temperature in the granulator, adjusting the amounts of undersized and oversized particles recycled to the granulator according to the measured temperature in the granulator. The present disclosure further relates to low dust producing uncoated granules of a hydrous nitrate mineral salt-based composition.

A composition including (a) at least one (thio)phosphoric acid triamide (T), where the (thio)phosphoric acid triamide (T) is one of N-n-butylthiophosphoric acid triamide (NBPT) and N-n-propylthiophosphoric acid triamide (NPPT), and (b) at least one specific herbicide.

The present disclosure provides desensitized fertilizer compositions that are resistant to detonation. The desensitized fertilizer compositions of the present disclosure are formed, under heat, from a reaction product of a base fertilizer material, such as ammonium nitrate, and a phosphate-based additive, such as ammonium polyphosphate. The resulting compositions include monoammonium phosphate (MAP), diammonium phosphate (DAP), and polyphosphate crystals distributed throughout the crystalline fertilizer material. The presence of the distributed MAP and DAP crystals is believed to stabilize the base fertilizer material and reduce or eliminate the detonation potential of the fertilizer material.
