Solutions are prepared by dissolving N-(n-butyl)-thiophosphoric triamide (NBPT) in one or more N-substitued morpholines and mixtures thereof. The solutions may be used in urea fertilizers to reduce nitrogen volatilization, or to reduce the odor of animal waste or urine. Methods of preparing urea fertilizers and the resultant products are also described.
