Humic acid lignite coal based liquid fertilizer

Abstract

The disclosed invention relates to novel fertilizing compounds comprising a combination of inorganic fertilizers and humic compounds. The combination produces a marked benefit over either type of substance individually, and also over previously known combinations of organic and inorganic fertilizers. The invention also relates to a method of production of such compounds.

What is claimed is: 
     
         1 . A method of producing a fertilizer composition, comprising:
 (a) placing a liquid solution of nitrogen and lignite into a container;   (b) mixing the nitrogen and lignite;   (c) adding phosphoric acid to the solution;   (d) mixing the phosphoric acid with the solution;   (e) adding water to the solution;   (f) mixing the water with the solution;   (g) adding potash to the solution;   (h) mixing the potash into the solution;   (i) filtering the solution; and   (j) placing the solution into a container.   
     
     
         2 . The method of  claim 1  wherein the first mixing step is performed for about 8 minutes. 
     
     
         3 . The method of  claim 1  wherein the second mixing step is performed for between about 10 minutes and about 12 minutes. 
     
     
         4 . The method of  claim 1  wherein the third mixing step is performed for about 10 minutes. 
     
     
         5 . The method of  claim 1  wherein the fourth mixing step is performed for about 20 minutes. 
     
     
         6 . The method of  claim 1  wherein the phosphoric acid comprises fertilizer grade phosphoric acid. 
     
     
         7 . The method of  claim 1  wherein the solution is filtered via gravity flow though a filter screen. 
     
     
         8 . The method of  claim 7  wherein the filter screen is a 200 mesh size. 
     
     
         9 . The method of  claim 1  further comprising adding a defoaming agent.
