Abstract Solubilities in the system CO(NH2)2-NH4NO3-(NH4)2S2O3-H2O were obtained at 0°C and pH values between 6.12 and 7.33. The new composition of matter, (NH4)6(S2O3)2(NO3)2·CO(NH2)2, was identified and characterized chemically and microscopically. Stable high-analyses solution fertilizers can be produced at 0°C utilizing waste ammonium thiosulfate solutions with standard ammonium nitrate and urea fertilizer materials. A 31-0-0-5.6S grade (%N-%P2O5-%K2O-Other) fertilizer solution can be formed at 0°C when NH4NO3/CO(NH2)2 is about one. Stable 30% total nitrogen solutions containing up to 10% sulfur can be produced at other NH4NO3/CO(NH2)2 ratios.
