Organic-based fertilizer
The subject invention provides methods for producing homogenous organic base fertilizer for plant nutrition and soil fertility. Also provided by the subject invention are value added fertilizer products for plant nutrition and soil fertility and concentrated liquid formulations/nutrient supplements that provide the value added nutrients to fertilizer products. Methods according to the invention involve the application of concentrated liquid(s) and/or dry formulation(s) comprising a mixture of one or more plant nutrient(s), one or more additional organic compound(s), one or more penetrate(s), and one or more optional supplement(s) into one or more organic base material(s). These organic base materials include, and are not limited to, biosolids, activated sludge, municipal compost, animal manures (e.g., horse, cow, chicken, pig, and sheep), and composted organic byproducts.
1. A method of preparing high quality homogenous slow-release organic-base fertilizer comprising:
a. preparing a liquid concentrate comprising nitrogen, potassium, phosphorus, ammonium nitrate, bacteria, humic acid, one or more wetting agent and natural enzymes;
b. adding said liquid concentrate to a biosolid;
c. mixing the liquid concentrate-biosolid composition in a mixing means; and
d. drying said composition.
2. The method according to claim 1 , wherein said composition is dried at a termperature of 85° to 100° C.
3. The method according to claim 1 , wherein said mixing means is a rotating mixer or blender.
4. The method according to claim 1 , wherein said mixing means is a granulation drum.
5. The method according to claim 2 , wherein said mixing means is a rotating mixer or blender.
6. The method according to claim 2 , wherein said mixing means is a granulation drum.
7. The method according to claim 1 , comprising adding a liquid concentrate that contains nitrogen (N), phosphorus (P), and potassium (K) in amounts that provide N-P-K percentages (by weight) of about 6-1-0, 7-1-0, 8-1-0, 9-1-0, 10-1-0, 12-1-0, 4-2-4, or 6-2-4 for a finished product.
8. The method according to claim 2 , comprising adding a liquid concentrate that contains nitrogen (N), phosphorous (P), and potassium (K) in amounts that provide N-P-K percentages (by weight) of about 6-1-0, 7-1-0, 8-1-0, 9-1-0, 10-1-0, 12-1-0, 4-2-4, or 6-2-4 for a finished product.
9. The method of claim 1 , further comprising the addition of water soluble and/or extended release coatings.
