  • Additive containing N-(N-butyl)thiophosphoric triamide for urea-based fertilizer
    Patent number: 9512045
    Abstract: A dry flowable additive for aqueous urea-based fertilizers made of solid urea formaldehyde polymer (UFP), N-(n-butyl)thiophosphoric triamide (NBPT), and, optionally, dicyandiamide (DCD), wherein the liquid fertilizer containing the additive provides reduced nitrogen loss from the soil. Optionally, the dry additive may also be blended with molten or solid urea to form a solid urea-based fertilizer with reduced nitrogen loss from the soil.
