An improved solvent system for the formulation and application of N-alkyl thiophosphoric triamide urease inhibitors. These formulations provide safety and performance benefits relative to existing alternatives and enable storage, transport and subsequent coating or blending with urea based or organic based fertilizers. These formulations are comprised primarily of environmentally friendly aprotic and protic solvents (particularly dimethyl sulfoxide and alcohols/polyols) to stabilize the urease inhibitor.

The present invention relates to compositions for increasing a nitrogen source life span in plant growth mediums as well as methods of making these compositions. The invention also relates to compositions and methods of reacting a nitrogen source with one or more nitrification inhibitors using standard equipment for producing nitrogen sourced particles.

A fertilizer supplying animal nutrients including a core particle having an outer surface and comprising compounds containing animal nutrients, and a coating of urea on the outer surface of the core particle, and further a process of making the fertilizer including the steps of: screening animal nutrient core particles comprising a powdered substance containing an animal nutrient, to a preselected particle size; spraying melted urea onto the surface of the nutrient core particles to produce a coating on the nutrient core particles; granulating the nutrient core particles with sprayed melted urea to produce nutrient core granules; and cooling the nutrient core granules.

An improved nitrification inhibitor composition comprising UFP particles and a nitrification inhibitor, and optionally other components, is used as an additive for liquid and solid fertilizers, typically containing urea. The nitrification inhibitor particularly can be nitrapyrin and/or DMPP. Methods of making the compositions and their use are also disclosed.
