Description

A method for manufacturing compost using indigenous microorganisms {A METHOD FOR MANUFACTURING COMPOST USING INDIGENOUS MICROORGANISM}

The present invention relates to a method for manufacturing compost using indigenous microorganisms. Specifically, by collecting native microorganisms with excellent proliferative and reproductive ability and adding them to clippings and manure, it promotes fermentation, enabling rapid and high-quality compost production that can help plants grow, as well as removing odors. It relates to a method for manufacturing compost.

Composting is a stabilization process in which organic matter is normally decomposed by microorganisms, the final material of which must not adversely affect the environment, be usable in the soil, and be biochemically transformed into a humus-like material sufficient for storage. It is defined as the continuous biological treatment of organic components of a process or solid waste under artificial conditions.

In Korea, compost using livestock manure and compost using vegetable oil are mainly used. However, compost using livestock excreta generates odor in the process of treating livestock manure, and the content of ingredients is not constant depending on the type of livestock or breeding method. It has a disadvantage that it has to be fertilized by examining the component content before using it as a method (Nam, Y. et al. (2011), Korean J. Soil Sci. Fert. 43(5), pp.522~527). On the other hand, compost made by fermenting vegetable oil meal, the raw material of organic fertilizer, has the advantage of being used as a high-quality compost showing a high compost grade because the component content of the material is constant. Sawdust, etc., and these raw materials have a very low moisture content, so it is necessary to periodically supply sufficient moisture during the composting period, and there is a problem that a large amount of sawdust is required to control the organic-to-nitrogen ratio. Accordingly, there is a need for research on ways to reduce the occurrence of odors and speed up the manufacturing process in the manufacture of compost using livestock manure.

It is an object of the present invention to provide a compost manufacturing method comprising the step of inoculating clippings or livestock manure with a microbial progenitor using native microorganisms.

Another object of the present invention is to provide a compost prepared by the above method.

One aspect of the present invention comprises the steps of (a) installing a cedar lunch box containing rice or rice bran cooked with main grains in humus and collecting native microorganisms 7 to 14 days later; (b) mixing the collected native microorganisms with earth sugar and storing them for 1 to 4 weeks; (c) preparing a first microbial progenitor species by adding water-blended rice bran; And (d) the step of inoculating the first microorganism progenitor species of step (c) to clippings or livestock manure and fermenting; it relates to a compost manufacturing method comprising a.

In the present invention, "manure" refers to a material that is made by fermenting or rotting various materials such as grass, straw, and animal excrement, and has sufficient nutrients for plants to grow and can be decomposed by decay.

In the present invention, “indigenous microorganisms” refer to various soil microorganisms that have survived for a long time in an area. Generally, ingredients such as rice or rice bran cooked with main grains are put in humus, and the microorganisms transferred to the food after a certain period of time are collected. include that

Indigenous microorganisms vary depending on the soil and depth of the region, but more than 10 billion microorganisms live there, and there are various microorganisms that are not known until now. Indigenous microorganisms directly help the growth of crops through various actions such as supply of nutrients, growth of crops, production of promoting hormones, improvement of soil structure, pest control, and weeding. For example, Bacillus ( Bacillus ) and Pseudomonas ( Pseudomonas ) are known to help promote the growth of intestinal organs, disease control, and the like.

In the present invention, rice cooked with main grains was put in a cedar lunch box to collect soil microorganisms and used for microbial collection, and the cedar lunch box is suitable for collecting useful strains in compost production compared to general plastic lunch boxes or lunch boxes of other trees.

Specifically, in one embodiment of the present invention, after covering the cedar with Godubap in it, fixing it with Korean paper, fixing it, and burying it in the humus soil, when the microorganisms gather in the rice and become white and moist, put it in a jar and add brown sugar for a third of the microorganisms Proliferated.

At this time, in the present invention, rice bran mixed with water was added to promote microbial growth, and a microbial progenitor species solidified into powder was prepared.

In the present invention, the term “progenitor species” refers to a microbial mass produced by collecting, proliferating and propagating native microorganisms, and may be, for example, a microbial mass produced by collecting and fermenting native microorganisms for a certain period of time.

Specifically, the method may further include adding local soil to the first progenitor species of microorganisms in step (c) to prepare a second progenitor species of microorganisms. Local soil refers to the soil of the region to be used by inoculating the progenitor of microorganisms. For example, if it is intended to be used for pepper farming, it may be a step of adding soil from the pepper farming area.

It may further include; adding straw to the second progenitor species of microorganisms in step (c) in an amount of 4% to 6% by weight to prepare a third progenitor species of microorganisms.

The straw may be used without limitation, such as dry straw, wet straw, etc. as raw straw. Straw contains a large amount of Bacillus subtilis bacteria, so it can be added in the compost manufacturing process to promote fermentation.

In order to prepare a clipping material compost using the third progenitor microbial species, when the clipping material is added to the progenitor of the third microorganism, the rice bran liquid mixed with water may be additionally sprayed according to the amount of the clipping material added. At this time, the rice bran promotes the activity of indigenous microorganisms so that fermentation occurs well and compost can be produced quickly.

When native microorganisms are activated according to the addition of the progenitor of microorganisms, anaerobic reaction and anaerobic reaction occur simultaneously.

The humidity of the clipping material using the microbial progenitor may be 40 to 60%, and more specifically, the humidity of the clipping material may be maintained at 45 to 55%. At this time, when the temperature of the cutting material rises to 70° C. or more and the moisture evaporates due to the activation of the indigenous microorganisms, water may be additionally supplied to maintain the humidity.

The water may be used without limitation, such as surface water, ground water, seawater, and rainwater, but in general, general natural water such as surface water or groundwater may be used.

The surface water refers to water that does not permeate underground or does not evaporate and remains on the surface of the earth and flows through the ground, and it refers to water that is undisturbed in rivers, reservoirs, lakes, etc. have

The groundwater is water in which rainwater or surface water passes through the stratum and remains below the water table, and includes all of shallow water, deep water, spring water, and underflow water, and can be used without limitation.

The method may further include adding seawater to the third progenitor species of microorganisms in step (c) to prepare a fourth progenitor species of microorganisms. Specifically, seawater may be seawater from the East Sea, and the seawater from the East Sea may be used without limitation as long as it is seawater obtained from the East Sea, that is, the coastal waters of the Pacific Ocean located in the northeastern part of Asia.

It is known that the seawater of the East Sea is rich in dissolved oxygen. In addition, compared to the West Sea seawater, it is rich in inorganic nutrients such as nitrogen, silicon, and phosphate, and is rich in essential minerals such as magnesium, calcium, and sodium.

On the other hand, seawater contains abundant minerals, but has a high salinity, so it can be used by diluting water.

Specifically, adding a first mixture of seawater and water in a ratio of 1: 2500 to 3500 times; adding a second mixture of seawater and water in a ratio of 1 : 1200 to 1700 times; and a third mixture of seawater and water in a ratio of 1:600 to 800 times; adding in order may include.

The mineral components and inorganic nutrients contained in the seawater react with the progenitor of microorganisms to promote the activity of soil microorganisms, and have the effect of removing odor-causing components such as livestock manure, which is one of the main components of compost. .

In an embodiment of the present invention, the first to third mixtures of seawater were sequentially mixed with the microbial progenitor, applied under the straw in the chicken coop, and then water was sprayed. (Table 1).

The above results show that, in the case of compost fermented by adding the progenitor of microorganisms of the present invention to manure, good quality compost containing a large amount of microorganisms can be produced without any odor caused by livestock manure.

Another aspect of the present invention relates to a compost produced by the method.

The compost manufacturing method is the same as described above.

The compost has excellent proliferation and/or reproductive activity of indigenous microorganisms, and by adding straw and/or mineral-rich seawater, it is possible to provide a high-quality compost that can be utilized for crop cultivation using manure and clippings.

In the present invention, a microbial progenitor species in which the proliferation and reproduction of indigenous microorganisms is activated was prepared using a cedar lunchbox and rice bran, and by adding seawater containing a large amount of local soil, straw and/or mineral components to the microbial progenitor species, the crops, Even if compost is manufactured using livestock manure, there is no odor at all, and it has the effect of providing high-quality compost containing a large amount of organic matter and microorganisms.

It should be understood that the effects of the present invention are not limited to the above-described effects, and include all effects that can be inferred from the configuration of the invention described in the detailed description or claims of the present invention.

1 shows the process of collecting indigenous microorganisms.
2 shows the process of collecting and fermenting native microorganisms.
3 shows a process of preparing compost by inoculating a clipping material with a progenitor species of microorganisms prepared using indigenous microorganisms.
Figure 4 shows the humidity maintenance process in the process of preparing compost by inoculating the crops.
