IMPROVED LIQUID FORMULATIONS OF UREASE INHIBITORS FOR FERTILIZERS.

摘要

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.
