Beschreibung
Zusammenfassung:	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. Un aditivo de flujo en seco para fertilizantes acuosos basados en urea, elaborado de polímero de formaldehído de urea sólido (UFP = urea formaldehyde polymer), triamida N-(n-butil) tiofosfórica (NBPT = N-(n-butyl) thiophosphoric triamide), y, opcionalmente, diciandiamida (DCD), en donde el fertilizante líquido que contiene el aditivo proporciona reducida pérdida de nitrógeno del suelo. Opcionalmente, el aditivo seco también puede mezclarse con urea fundida o sólida para formar un fertilizante basado en urea sólida con reducida pérdida de nitrógeno del suelo.
