Abstract
A method and apparatus for making organic based fertilizer, the method including mixing organic material with phosphate, potash, or other inorganics and water if necessary. Acid is mixed with the organic and inorganic material mixture and the resulting mixture is permitted to cure for a sufficient period of time to allow the acid to chemically break down the material of the mixture. A first quantity of ammonia is then added to the mixture, and a second quantity of ammonia is added to the mixture to produce the finished fertilizer product. Quantities of the various ingredients are adjusted to provide a fertilizer that has a desired percentage make-up of the major fertilizer elements for a specific crop.
Claims13
A method for producing an organic based humic acid fertilizer containing a predetermined amount of an available inorganic material selected from the group consisting of nitrogen, phosphate, potash, sulfur, and mixtures thereof and having a desired final pH level in the finished fertilizer product, said method comprising the steps of:
- (a) mixing with an organic material selected from the group consisting of livestock and poultry manure, sewage sludge, separated garbage, cotton gin trash, fruit cannery waste, vegetable cannery waste, nut cannery waste, wood and paper pulp waste, spent mushroom compost, methane and alcohol solid wastes, lignite, leonardite, humate, coal and mixtures thereof, a sufficient amount of said inorganic material to provide said predetermined amount of said inorganic material in the fertilizer product;
- (b) blending with the mixture produced in step (a) a sufficient amount of acid to substantially reduce the pH thereof and to cause chemical breakdown of said organic material;
- (c) allowing the blended mixture to stand for at least 20 minutes;
- (d) blending with the mixture produced in step (c) a sufficient amount of a base material to raise the pH thereof to a level which is intermediate to a said final pH level;
- and
- (e) blending with the mixture produced in step (d) additional base material to raise the pH thereof to said final pH level.
A method of producing an organic based humic acid fertilizer containing a predetermined amount of an inorganic material selected from the group consisting of nitrogen, phosphates, potash, sulfur, and mixtures thereof and having a desired final pH level in the finished fertilizer product, said method comprising the steps of:
- (a) mixing with an organic material selected from the group consisting of livestock and poultry manure, sewage sludge, separated garbage, cotton gin trash, fruit cannery waste, vegetable cannery waste, nut cannery waste, wood and paper pulp waste, spent mushroom compost, methane and alcohol solid wastes, lignite, leonardite, humate, coal and mixture thereof, a sufficient amount of said inorganic material to provide said predetermined amount of said inorganic material in the fertilizer product;
- (b) blending the mixture produced in step (a) with a sufficient amount of an acid to substantially reduce the pH thereof and to cause chemical breakdown of said organic material;
- (c) allowing the blended mixture to stand for at least 20 minutes;
- (d) blending with the mixture produced in step (c) a sufficient amount of ammonia to raise the pH thereof to a level which is intermediate to said final pH level;
- (e) cooling the mixture produced in step (d) by exposing the mixture to an oxygen-containing gas;
- and
- (f) blending with the cooled mixture a sufficient quantity of ammonia to raise the pH to said desired pH level.
