1. Compost composition preparation and mixing step (S100)

The compost composition preparation and mixing step (S100) is a step of preparing a compost composition for preparing compost and then mixing the compost composition at a constant weight ratio.

In the preparation and mixing step (S100) of the compost composition, after preparing a compost composition consisting of humus, rice straw, rice bran, sericite powder, loess, fermented pine cone crushed product, shell powder, and fermented sawdust, the compost composition is mixed with humus 150 to 200 parts by weight. , 20 to 40 parts by weight of rice straw, 10 to 30 parts by weight of rice bran, 1 to 10 parts by weight of silkworm powder, 5 to 15 parts by weight of loess, 5 to 15 parts by weight of fermented pine cone crushed material, 15 to 25 parts by weight of shell powder and fermentation of sawdust It can be mixed in a weight ratio of 10 to 30 parts by weight of water.

The humus refers to soil generated by decaying and decomposing leaves or small branches by microorganisms, and is widely used in horticulture and has good drainage and a lot of moisture and nutrients. In addition, since the humus is porous, it has good drainage, strong retention of moisture and nutrients, increases geothermal temperature, is rich in nutrients, and artificially collected and stacked fallen leaves to decay. There are naturally decayed and decomposed ones, and generally, the fallen leaves of broad-leaved trees have more active ingredients than coniferous trees, and it is good for the faster ripening.

The rice straw contains a lot of useful microorganisms including Bacillus bacillus (Bacillus bacteria) having various functions such as antibacterial activity, and is rich in organic matter, phosphoric acid, silicic acid, and nitrogen. As well as changing into a compound, it can play a role of promoting the growth and development of seeds and plants by improving the bearing capacity, cohesion and cohesion of the soil.

Rice bran is a by-product after milling rice. Rice has a high sugar content compared to other grains, but has a low content of fat and protein, and in particular, has a very low content of minerals and vitamins. However, rice sprouts contained in rice are recently recognized for their functionality as a good nutrient source containing high-quality protein, fat, and minerals and vitamins A, B, E, etc. compared to endosperm, and rice oil is also known as oleic acid, linoleic acid, and linolenic acid. In addition to containing a large amount of unsaturated fatty acids such as phytosterol, γ-oryzanol and tocopherol derivatives such as anti-cancer, anti-hypertension, anti-blood coagulation, and high content of antioxidants, it has been in the spotlight as a new functional material. Are receiving.

Since the sericite powder is used after foaming sericite, an air layer is formed inside the powder to control humidity, as well as preventing the occurrence of deodorization or mold, and having negative ions and far-infrared rays.

The loess adsorbs and decomposes impurities and contaminants into the space between the particles, is rich in oxygen, and emits far infrared rays. The far-infrared rays emitted from the loess have a wavelength of 8 to 14 μm, and the far-infrared rays of the loess activate the cells of the cells to promote metabolism. In the yellow soil, far-infrared rays are radiated and absorbed by the human body, metabolism and blood circulation are activated to prevent aging of the human body, and various adult diseases such as chronic fatigue can be prevented. When far-infrared rays are radiated from the loess, bacteria are weakened due to the thermal action, and it may help to promote the production of cell tissues.
