Organic liquid fertilizer
A fertilizer derived from an organic source and a method of making are provided. The fertilizer of the present invention advantageously has a nitrogen content greater than 4%. The method of making the fertilizer also produces potable water.
1. An aqueous liquid fertilizer comprising:
at least 4% dissolved ammoniacal nitrogen derived from a plant or animal-sourced waste; and
residues of at least one organic acid.
2. The aqueous liquid fertilizer of claim 1 , wherein the at least one organic acid is selected from the group consisting of citric acid, lactic acid, L-malic acid, acetic acid, formic acid, oxalic acid, and uric acid.
3. The aqueous liquid fertilizer of claim 1 , wherein the fertilizer has a pH of between 5 and 7.
4. The aqueous liquid fertilizer of claim 1 , wherein the fertilizer comprises from 40,000 to 750,000 ppm of dissolved solids.
5. The aqueous liquid fertilizer of claim 1 , wherein the fertilizer comprises from 0 to 20,000 ppm of suspended solids, wherein the suspended solids have a particle size of less than or equal to 24 microns.
6. The aqueous liquid fertilizer of claim 1 , wherein the fertilizer meets the criteria for USDA organic certification under the National Organic Program.
7. The aqueous liquid fertilizer of claim 1 , wherein the fertilizer comprises from 4% to 10% sulfur.
8. The aqueous liquid fertilizer of claim 1 , wherein the liquid fertilizer comprises 4-10% nitrogen, from about 1% to 10% potash, less than 10% sulfur, and is phosphate free.
9. The aqueous liquid fertilizer of claim 1 , wherein the fertilizer comprises at least 5% dissolved ammoniacal nitrogen.
10. An aqueous liquid fertilizer comprising:
at least 4% dissolved ammoniacal nitrogen derived from a plant or animal-sourced waste; and
residues of at least one acid,
wherein the fertilizer meets the criteria for USDA organic certification under the National Organic Program.
11. The aqueous liquid fertilizer of claim 10 , wherein the at least one acid comprises an organic acid.
12. The aqueous liquid fertilizer of claim 11 , wherein the organic acid is selected from the group consisting of citric acid, lactic acid, L-malic acid, acetic acid, formic acid, oxalic acid, and uric acid.
13. The aqueous liquid fertilizer of claim 10 , wherein the fertilizer has a pH of between 5 and 7.
14. The aqueous liquid fertilizer of claim 10 , wherein the fertilizer comprises from 40,000 to 750,000 ppm of dissolved solids.
15. The aqueous liquid fertilizer of claim 10 , wherein the fertilizer comprises from 0 to 20,000 ppm of suspended solids, wherein the suspended solids have a particle size of less than or equal to 24 microns.
16. The aqueous liquid fertilizer of claim 10 , wherein the fertilizer comprises at least 5% dissolved ammoniacal nitrogen.
17. An aqueous liquid fertilizer having a pH of between 5 and 7 and comprising at least 5% dissolved ammoniacal nitrogen derived from a plant or animal-sourced waste.
18. The aqueous liquid fertilizer of claim 17 , wherein the fertilizer further comprises residues of at least one organic acid.
