Patent Application

The present invention relates to fertilizer compositions, and more particularly to a bio-fertilizer and the method for manufacturing same.
The continuous use of chemical pesticides and fertilizers on plants, bushes, and trees, and especially in agricultural settings in the production of crops, has created a variety of ecological problems. As the world and national populations have increased, farmers and horticulturalists have come to rely increasingly upon chemically synthesized fertilizers and chemical pesticides to maintain the same level of crop production.
More and more, organic base byproducts, including, but not limited to, biosolids, activated sludge, municipal compost, animal manures (such as cow, horse, pig, sheep, or chicken manure), and composted organic byproducts containing various plant nutrients, are being produced as a result of industrial and agricultural activities and processes. The nutrient content of these byproducts is generally low and these byproducts have been used as fillers, soil amendments or landfill because of their low nutrient value.
Turfgrasses, whether on a fairway, putting green or tee require rather large amounts of nitrogen fertilization during the growing season to maintain a desirable dark green color. There are numerous inorganic nitrogen fertilizer materials that can supply this needed nitrogen very adequately. However, these inorganic salts are very soluble in the soil solution and are readily converted to the nitrate form and leach, thus making frequent application of these materials necessary. Natural and synthetic slow-release organic nitrogen materials are available which release nitrogen over a longer period of time, thus reducing the frequency of application, while increasing the uniformity of turf growth and appearance throughout the season. Natural and synthetic slow-release nitrogen sources are influenced differently by the various environmental factors to which they are exposed. The present invention is advantageous because it increases the nutrient value of organic base byproducts and can be enhanced in such a way as to produce a high nutrient value homogenous organic-base fertilizer. Also, the fertilizers in the present invention have high nutrient values.
In one aspect, the present invention provides a method for producing homogenous organic base fertilizer for plant nutrition and soil fertility. Also, the fertilizer in the present invention can be added for plant nutrition and soil fertility, and concentrated liquid formulations/nutrient supplements can be added to the fertilizer in the present invention. 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 penetrant(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.

In one aspect, a method of preparing homogenous bio-fertilizer that may include steps of preparing a liquid concentrate comprising nitrogen, potassium, phosphorus, ammonium nitrate, bacteria, humic acid, one or more wetting agent, natural enzymes, azomite powder, trace mineral and basalt rock powder; adding said liquid concentrate to a biosolid; mixing the liquid concentrate-biosolid composition in a mixing means; and drying said composition.
In one embodiment, the bio-fertilizer in the present invention can be concentrated liquid formulations (nutrient supplements). These liquid nutrient supplements can contain the following components: one or more plant nutrient(s), one or more organic compound(s), one or more penetrant(s), and/or one or more additional soil and plant additive(s). Plant nutrients may include macronutrients such as nitrogen (N), phosphorus (P), potassium (K), secondary nutrients such as calcium (Ca), magnesium (Mg), and micronutrients such as Iron (Fe), zinc (Zn), manganese (Mn), copper (Cu) and boron (B).

Mixing means may include, and are not limited to, rotating mixers, other rotating containers, or granulation drums. The mixing means may rapidly rotate to mix and incorporate the liquid concentrate into the organic base materials. Concentrated liquid formulations or concentrated nutrient supplements are terms that may be used interchangeably throughout the specification.
