ORGANIC LIQUID FERTILIZER AND PROCESS OF MAKING
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 . A method for making a liquid fertilizer comprising the steps of:
a) obtaining an liquid organic waste filtrate;
b) adding an acid; and
c) performing an evaporation process on the liquid organic waste filtrate.
2 . The method of claim 1 , wherein the method further comprises the step of adding a second acid after performing the evaporation process to create a liquid fertilizer.
3 . The method of claim 1 , wherein the acid is citric acid.
4 . The method of claim 3 , wherein the citric acid is added in an amount of from about 0.1 lbs/gallon to 2.0 lbs/gallon.
5 . The method of claim 1 , wherein the liquid organic waste filtrate contains Ammoniacal Nitrogen.
6 . The method of claim 1 , wherein the acid is added in an amount sufficient to change the pH of the liquid organic waste filtrate to a pH of 7 or less.
7 . The method of claim 1 , wherein the liquid organic waste filtrate is produced by the steps comprising:
a) obtaining liquid organic waste; and
b) removing suspended solids.
8 . The method of claim 7 , wherein the step of removing the suspended solids is performed by a filtration mechanism.
9 . The method of claim 7 , wherein the liquid organic waste filtrate contains less than 1,200 ppm suspended solids.
10 . The method of claim 7 , wherein the removed suspended solids are particles that will not pass through a 270 Dalton membrane under 500 psi of pressure.
11 . The method of claim 7 , wherein the liquid organic waste comprises poultry manure and water.
12 . A method for making a liquid fertilizer comprising the steps of:
a) obtaining liquid organic waste;
b) removing suspended solids from the liquid organic waste;
c) adding an acid; and
d) performing an evaporation process.
13 . The method of claim 12 , wherein steps a) and b) form a liquid organic waste filtrate.
14 . A liquid fertilizer comprising at least 4% Nitrogen, derived from a liquid organic waste filtrate starting material.
15 . The liquid fertilizer of claim 14 , wherein the Nitrogen content is 6%.
16 . The liquid fertilizer of claim 14 , wherein said liquid fertilizer is free of pathogens.
17 . The liquid fertilizer of claim 14 , wherein the liquid fertilizer contains about 5% potash.
18 . The liquid fertilizer of claim 14 , wherein the liquid fertilizer contains about 590,000 ppm dissolved solids.
19 . The liquid fertilizer of claim 14 , wherein the organic starting material is animal manure.
20 . The liquid fertilizer of claim 19 , wherein the animal manure is poultry manure.
21 . The liquid fertilizer of claim 14 , wherein the Nitrogen is in a form available to plants.
22 . The liquid fertilizer of claim 14 , wherein the liquid fertilizer meets the criteria for USDA organic certification.
