Abstract

PURPOSE: An organic mineral fertilizer is provided to reduce manufacturing costs and to contain essential substances for growth and ripening of the crops by reacting slag, which is generated from a converter for manufacturing steel with waste food. CONSTITUTION: The organic mineral fertilizer contains 10 wt.% or more of OM(Oligosaccharide Molecular), 40 wt.% or less of OM/N(Oligosaccharide Molecular/Nitrogen), 35-45 wt.% of CaO, 3.5-7.5 wt.% of SiO2, 12-18 wt.% of MgO, 3-7 wt.% of Fe2O3, 2-5 wt.% of MnO, 0.3-0.6 wt.% of P2O5, 0.3-1.8 wt.% of Al2O3, and 0.05 wt.% or less of S and other essential substances. Once food waste and slag, which are generated from a converter for manufacturing steel, are mixed, cationic elements contained in the slag, such as Ca, Mg, P, S, Mn, Si, bond to anions derived from organic compounds of OM/N so that they form aliphatic ester having long chain. The food waste and the slag are characterized by being mixed in a ratio of 40:60.

Description

A fertilizer containg organic compounds and minerals}

The present invention relates to an organic mineral fertilizer prepared from food waste and by-products generated in steel mills, and more specifically, by using steelmaking converter slag generated as a by-product from general household food waste and steel mills, manufacturing costs compared to conventional fertilizers. It provides an organic mineral fertilizer that is inexpensive and promotes the growth, growth and fruiting of crops, while also contributing to the reforming of acidic and aging soils.

In general, the soil is scattered with many elements necessary for the development, growth, and fruiting of crops, and when chemical fertilizers are used, crops grow well temporarily and yields increase, but over time, the distance of crops due to overuse of fertilizers. Problems such as deepening and low yields have existed. In order to solve these problems, various fertilizers and fertilizers such as nitrogen, phosphate, caryzil, clay and organic matter have been developed and used for agriculture, but also nitrogen, ammonia, sulfur, phosphoric acid, water-soluble phosphoric acid, goto, Consists of only a few main elements, such as silicic acid, carry and organic matter, has the disadvantage that it does not provide enough of the various components required for crops.

Accordingly, the agricultural field currently uses organic fertilizers produced in accordance with the content of nitrogen, phosphoric acid and carry, which are three elements necessary for forming plants.

The molecular structure of the organic compound is composed of carbon, oxygen, hydrogen, etc., which are usually present in four forms: protein, carbohydrate, lipid, and nucleic acid. Proteins play a role in the storage, transport, composition, contraction and defense of enzymes and hormones, and carbohydrates exist as polysaccharide derivatives composed of monosaccharide derivatives. Lipids are long-chain fatty acids or esters that help proteins or carbohydrates function. Or nucleic acid plays a role in mediating for constructing the binding structure between them. The organic component (OM / N; Oligosaccharide Molecular / Nitrogen) provides many of the components necessary for crops, but the soil requires many other elements, depending on the plant's properties.

Therefore, the present invention uses a steelmaking converter slag generated as a by-product from household food waste and steel mills, a wider range of ingredients necessary for the development, growth and deletion of crops, while manufacturing costs are lower than conventional fertilizers or organic fertilizers. To provide organic mineral fertilizer.

Therefore, the fertilizer of the present invention promotes the deletion and growth of crops, and provides an excellent effect of contributing to the reforming of acidic soils and aged soils.

The organic mineral fertilizer of the present invention is at least 10% by weight of Oligosaccharide Molecular (OM) and at most 40% by weight of Oligosaccharide Molecular / Nitrogen (OM / N), 35-45% by weight of CaO, 3.5-7.5% by weight of SiO ₂ , MgO 12-18 Weight%, Fe ₂ O ₃ 3-7%, MnO 2-5%, P ₂ O ₅ 0.3-0.6%, Al ₂ O ₃ 0.3-1.8%, S 0.05% by weight or less and other unavoidable components Include.

The fertilizer of the present invention can be produced by using minerals directly as raw materials, but it is preferable to use general food debris and by-products generated in steel mills, in particular steel converter slag.

In other words, the fertilizer of the present invention is prepared by crushing and mixing the slag generated as a by-product from steel mills as a mineral source while fermenting food waste, which is a waste after human diet, as an organic content. Specifically, the fertilizer of the present invention is a cation in the addition of elements in the steel industry wastes such as Ca, Mg, P, S, Mn, Si to the OM / N generated by fermenting the waste of the general food waste Ca, Mg, P, S, Mn, Si or the like is taken in the form of anion derived from an organic compound.

Therefore, the fertilizer of the present invention has a variety of components that were not seen in the conventional fertilizer, unlike the fertilizers that have been used until now, alkaline and acidic substances possessed in the inorganic material can be utilized as a fertilizer in the form of mixed with the organic material have. Organics and inorganics become neutral in chemical reactions when combined. However, in the present invention, by using a method of adding and combining inorganic substances while treating organic substances other than chemicals, organic substances are present in the form of long-chain fatty acid esters because they are accumulated and fermented in inorganic substances rather than in the air. When this is ground and milled into fine particles, it becomes the organic mineral fertilizer of the present invention.

Hereinafter, each component contained in the fertilizer of this invention is demonstrated concretely.

In the fertilizer of the present invention, containing at least 10% by weight of OM and at most 40% by weight of OM / N is preferable as the optimum value in the mixing relationship between dietary food waste and minerals.

In addition, the CaO component promotes the growth, growth and deletion of plants by Ca, and serves to prevent acidification of the soil. In consideration of the balance and proper range of crops, the CaO content in the fertilizer is preferably in the range of 35-45% by weight.

SiO ₂ component contained in the fertilizer of the present invention is attached to the outer wall of the crop serves to prevent pests, for combination with the general soil is preferably in the range of 3.5-7.5% by weight.

MgO in the components of the fertilizer provides the effect of inhibiting the acidification of the soil as a major promoting element necessary for the chlorophyll composition of the crop, it is preferable to include in the range of 12-18% by weight in the fertilizer of the present invention. If it is 12% by weight or less or 18% by weight or more, the shape and taste of the fruit cannot be utilized, which is not preferable. In addition, in the present invention, MgO is present together with MnO, Fe ₂ O ₃ , P ₂ O ₅ , S and the like to play an important role in the chlorophyll composition of the plant, these contents are required as a general content for improving the acidic soil and promote plant growth Contained.

In addition, Al ₂ O ₃ component of the invention is good as far as possible, because the less detrimental to plant growth.

Fertilizer according to the present invention is prepared by loading and fermenting the food debris and converter slag in a weight ratio of 40:60, and then pulverized as is to produce a particle size selection process.

Hereinafter, the present invention will be described in more detail with reference to Examples. However, these examples are presented to specifically illustrate the present invention, but the scope of the present invention is not limited by these examples.
