AI Technical Summary
Existing liquid urease inhibitors have poor stability, are easily decomposed, and have poor compatibility with liquid fertilizers, resulting in low urea nitrogen utilization and serious ammonia volatilization loss. Furthermore, existing solid formulations are inconvenient to use and do not mix evenly.
A highly efficient and stable liquid urease inhibitor was prepared by using a synergistic formulation system of active ingredients, organic solvents, surfactants and stabilizers, and controlling the pH value within a weakly acidic range of 3.0 to 5.5, ensuring compatibility with liquid fertilizers and long-term storage stability.
It significantly inhibits soil urease activity, delays urea hydrolysis, reduces ammonia volatilization loss by 40% to 60%, increases urea nitrogen utilization rate by 15 percentage points, and maintains an effective component decomposition rate of less than 5% after 2 years of storage at room temperature. It is also stable in the long term when mixed with liquid fertilizer.
