(A) removing antibiotics contained in animal feces; (b) fermenting the animal excrement by inoculating the microorganism into the animal excrement pretreated in the step (a); (c) mixing the animal excrement fermented in the step (b) with the by-product of the crop and the by-product of the herb medicine to produce a compost composition; And (d) mixing the compost composition with sawdust, rice bran, and by-product byproduct to produce a composite compost (FIG. 1).

The step (a) is a step of pretreating the animal excrement to remove the antibiotic contained in the animal excrement.

The livestock excrement can utilize the livestock excrement derived from barnyardgrass, swine, horse mackerel or straw.

Generally, in livestock farms, various kinds of antibiotics are injected into livestock to increase the resistance of the livestock to increase the livestock breeding capacity so as to increase the livestock breeding capacity.

The antibiotic may be selected from the group consisting of sulfonamide, quinolone,? -Lactam, aminoglycoside, macrolide, tetracycline, glycopeptide, (Lincosamide) are mainly used. The excrement of the livestock to which the antibiotics are injected may include antibiotics. When the excrement is supplied to the soil, the antibiotics leach out into the soil, causing antibiotic resistant bacteria to be expressed or a threat to aquatic ecosystem.

In this step, when the compounded compost is supplied to the soil by removing the antibiotic contained in the excrement of the livestock, the amount of the antibiotic discharged can be minimized to prevent environmental pollution, and the livestock by-products such as livestock excrement can be effectively recycled .

For this purpose, the animal excrement may be configured to remove the antibiotic component contained in the animal excrement using an ozone oxidation method, an oxidizing agent treatment method, a photocatalytic treatment method, an ultraviolet irradiation method, or a plasma treatment method.

For example, in order to remove the antibiotics contained in the animal excrement by using the plasma treatment method, when plasma is irradiated to the animal excrement using various known types of plasma reactors, ozone (O ₃ ) , Hydroxyl radical (OH ^- ), hydrogen peroxide (H ₂ O ₂ ) and the like can be generated, and the antibiotic contained in the livestock by-product can be oxidized and decomposed to minimize the amount of antibiotic contained in the animal excrement .

In step (b), the step of fermenting the animal excrement by inoculating the microorganism into the excrement of livestock which has been pretreated as described above to remove the antibiotic is included in the animal excrement so as to effectively supply nutrients to the crop when the compost is manufactured And to ferment the animal excrement as a microorganism so as to break down the nutrients that have been lost.

In this step, microbes capable of promoting plant growth during fermentation of the livestock excrement can be inoculated into the animal excrement, and the microorganism is constructed to inoculate endophytic bacteria to supply the complex fertilizer to the plants The microorganism plays a role of supplying an effective ingredient to plants by forming a symbiotic relationship with plants, and the microorganism can serve to decompose the active ingredient of the animal excrement by utilizing the animal excrement as a nutrient, And can be configured to further promote plant growth.

In the present invention, microorganisms of the genus Pseudomonas or Enterobacter may be inoculated into the animal excrement so as to function as described above.

For example, Pseudomonas brassicaceum ( Pseudomonas brassicaceum ) and Enterobacter asburiae among the microorganisms of the genus Pseudomonas are fermented to produce nutrients and the fermentation process as described above It is possible to lower the level of ethylene, a plant hormone known to inhibit plant growth and promote senescence, and to maintain the growth of plants even under stress conditions, have.

The fermentation may be carried out at a temperature of 25 to 40 ° C for 24 to 360 hours to sufficiently ferment the microorganisms and ferment the fermentation of the animal excrement sufficiently.

In the step (c), the compost composition is prepared by mixing the livestock excrements fermented by the microorganisms with the crop by-products and the herbal medicine by-products. In this step, the crop by-products and the herb by- And can be utilized in the manufacture of composite compost.

In the case of using only domestic livestock excretion in the production of fertilizer, the excessive nitrogen component contained in the livestock excrement may inhibit the growth of the plant, and the amino acids and various minerals necessary for the growth of the crops are not sufficient, And the insect pests are caused by the decrease of the immunity, the yield of the plants is decreased, and the quality of the plants is also lowered.

Accordingly, in the present invention, it is possible to construct a composite fertilizer that provides a balanced nutrient and an effective ingredient by mixing the crop by-product and the herbal by-product with the fermented livestock excrement.

The crop by-products contain a balanced amount of active ingredients and nutrients necessary for plant growth, and can be configured to use mass-harvesting raw materials in the enrichment industry and food manufacturing industry. The crop by-products can be used in garlic, onion, corn, melon, watermelon, Pepper, peach, Chinese cabbage, radish, carrot, coffee, and the like.

In addition, even after the extraction of the medicinal herb by-products is completed, significant amounts of amino acid, carbohydrate and saponin components remain, and various nutrients required for plant growth are distributed uniformly, and carbon assimilation can be activated, It is possible to impart an ability such as a sterilizing action and a detoxifying action to promote fruit growth.

The medicinal product by-products can be constituted so as to use a raw material which can be mass-collected in the medicine field or the food manufacturing field and can be a byproduct produced from medicinal materials such as ginseng, red ginseng, dasoo, Can be used.

The compost composition prepared by mixing the byproducts of crops and herbal medicines by fermented livestock excrements as described above can uniformly distribute the balance of active ingredients and nutrients required for plant growth.

To this end, the composting composition comprises 20 to 60% by weight of the animal excrement, 38 to 70% by weight of the crop by-product, and 2 to 10% by weight of the herb medicine by-product based on the total amount of the compost composition, And nutrients can be produced. The composition can be diversified according to the use of the compost and can be utilized as a compound fertilizer for culturing various plants.

They are preferably used in a size of 5 to 50 mesh to sufficiently supply various active substances and nutrients required for plant growth and provide a sufficient surface area. A shredded product can be used.

In the step (d), the compost composition prepared as described above is mixed with sawdust, rice bran, and by-product of byproducts to produce a composite compost.

The sawdust and the rice bran can absorb and retain nutrients and moisture three times or more based on their own weight, and can increase the moisture retentivity, air permeability and bubbling property of the soil.

When the compost composition is mixed with sawdust and rice bran, the active ingredient contained in the compost composition is adsorbed to the sawdust and rice bran, and when the produced composite compost is supplied to the soil, the compost composition is fermented and decomposed with fibrin and lignin The active ingredient contained in the compost composition can be gradually released and continuously remain in the soil for a long period of time of one year or more, so that the active ingredients and nutrients contained in the complex compost can be continuously supplied.

The byproducts of Aronia include a large amount of antioxidants such as anthocyanin or polyphenol. When added to the above-mentioned compound fertilizer, the aronia byproduct improves the immunity of plants against anaerobic microorganisms and viral bacteria remaining in the soil, To promote the growth of plants.

In order to achieve the above-mentioned advantageous effects, the combined compost includes 29 to 55 wt% of the compost composition based on the total combined compost, 40 to 70 wt% of the sawdust and rice bran, 1 to 5% by weight based on the total weight of the composition.

Also, in this step, the composite compost produced by mixing the compost composition, sawdust, rice bran, and by-product as described above may be dried to a moisture content of 20 to 40% to produce a solid compost, The compost can be molded into a compost for various purposes.
