Urea phosphite
Urea Phosphite is a new composition of matter useful as a fertilizer and as a fungicide. It is made by reacting phosphorous acid with urea. Urea Phosphite is characterized by being a liquid produced in an unprocessed reaction, and by having phosphite as a phosphorus source and urea as a nitrogen source. The reaction products may be separated, blended with an admix and spray dried, or, dissolved in water.
1. A liquid composition of matter consisting of urea phosphite prepared by:
mixing a solid urea with a solid phosphorous acid at a temperature in the range of about 15° C. to about 100° C., wherein the urea and phosphorous acid are in a molar ratio of urea to phosphorous acid ranging from about 2:1 to about 1:2, and
without adding water, allowing a clear, colorless liquid indicating urea phosphite to form from said mixture of solids.
2. The composition of matter of claim 1 having the following chemical formula: CO(NH 2 ) 2 .H 3 PO 3 .
3. The composition of claim 1 prepared at room temperature.
4. The composition of claim 1 wherein the urea and phosphorous are blended for an hour.
