⚗️ Production Method:

NBPT is synthesized through a reaction between n-butylamine and thiophosphoryl triamide intermediates under controlled temperature and inert conditions. Strict quality control ensures high stability, purity, and field effectiveness.


🧬 Mode of Action:

NBPT functions as a urease inhibitor. It temporarily blocks the activity of urease, the enzyme that catalyzes the hydrolysis of urea into ammonia. This delay reduces ammonia volatilization loss, allowing more nitrogen to remain in the soil for plant uptake, improving crop yield and reducing environmental pollution.


🌾 Applications:

  • Fertilizer Additive: Used as a coating agent for urea or UAN (urea ammonium nitrate) solutions.

  • Agricultural Efficiency: Enhances nitrogen use efficiency in corn, wheat, rice, and grasslands.

  • Environmental Impact: Minimizes ammonia emissions and nitrogen runoff, contributing to sustainable farming practices.

  • Blended Fertilizer Production: Can be used in advanced controlled-release fertilizer formulations.


✅ Key Benefits:

  • Boosts nitrogen efficiency by up to 40%

  • Compatible with most types of urea-based fertilizers

  • Environmentally friendly and biodegradable

  • Reduces frequency of fertilizer application

  • Increases crop yields and fertilizer ROI
