Description

Natural organic compound fertilizer and its manufacturing method {Organic fertilizer and preparing method thereof}

The present invention relates to a natural organic complex fertilizer including liquid manure generated in a system for recycling organic waste resources such as food waste and manure, and a method for manufacturing the same, and more particularly, to a method for handling and useability by removing odor of liquid manure. The present invention relates to a natural organic complex fertilizer capable of improving, promoting plant growth, and improving yield and quality, and a method of manufacturing the same.

Organic waste is a waste resource containing organic matter and includes food waste, food industry waste, livestock manure, forest by-products, fishery by-products, and the like. Organic waste resources are increasing exponentially in size and amount due to urban industrialization and population growth.Since most of them are composed of organic materials, when landfilled and disposed of, severe odors occur due to corruption and are discarded. Leachate leaked during the process pollutes the soil, groundwater, and nearby surface water.

Previously, some organic waste resources, especially food waste, were disposed of in the ocean, but due to the deepening of marine pollution caused by ocean dumping, ocean dumping of food waste was banned in 2012, and accordingly, organic waste resources were disposed of on land. Research on how to dispose of them or how to process organic waste resources and use them as fertilizers or renewable energy sources is steadily progressing.

Organic waste resources contain a large amount of organic matter and components necessary for the growth of crops, such as nitrogen, phosphorus, and potassium, and are highly valuable as fertilizers, so they are mainly recycled as fertilizers.Generally, metals and plastics included in organic wastes It consists of a system that removes and pulverizes foreign substances in and dehydrates it, ferments it under aerobic or anaerobic conditions, separates it into solid compost and liquid fertilizer, and recycles it as fertilizer.

The compost obtained through the recycling system of organic waste resources is easy to handle and has relatively little odor, so it is widely used as fertilizer for agricultural crops, but in the case of liquid manure, it is difficult to use despite its excellent performance as a fertilizer. This odor is not used as fertilizer because it is continuously generated even though it goes through a process of maturation through aeration. In general, it is discharged after water treatment at a high cost.

Accordingly, there is a need to develop a technology that can be recycled as fertilizer by reducing the odor of liquid manure generated in the process of recycling organic waste resources.

The useful microorganism may include at least one or more microorganisms selected from the group consisting of yeast, lactic acid, photosynthetic bacteria, actinomycetes, and filamentous bacteria.

The natural organic complex fertilizer of the present invention includes liquid manure generated in a system for recycling organic waste resources such as food waste or manure, and removes odors generated from the liquid manure, thereby improving the handling and usability of the liquid manure.

In addition, the natural organic complex fertilizer promotes the growth of plants, and can improve the yield and quality.

Before describing in detail through preferred embodiments of the present invention, terms or words used in the present specification and claims should not be construed as being limited to a conventional or dictionary meaning, but a meaning consistent with the technical idea of the present invention. And should be interpreted as a concept.

Throughout this specification, when a certain part "includes" a certain component, it means that other components may be further included rather than excluding other components unless otherwise stated.

First, the present invention relates to a natural organic complex fertilizer and a method for manufacturing the same, which improves handling and usability by removing the odor of liquid manure generated in a recycling system for organic waste resources such as food waste or manure.

An embodiment of the present invention relates to a natural organic complex fertilizer comprising liquid manure obtained through anaerobic fermentation or aerobic fermentation of organic waste resources, natural mineral powder containing rare earth elements, useful microorganisms and dispersants.

More specifically, the natural organic complex fertilizer contains 25 to 55% by volume of liquid manure, 24 to 45% by volume of natural mineral powder, 15 to 46% by volume of useful microorganisms, and 0.5 to 3.0% by volume of a dispersant.

The liquid fertilizer is a liquid fertilizer generated in the process of recycling organic waste resources.For example, food waste is digested under anaerobic conditions, and only liquid components are separated from the digested mixture and used as liquid fertilizer, or separated liquid components The fertilized fertilizer may be used as liquid fertilizer by injecting air or air and microorganisms together, but is not limited thereto, and any liquid fertilizer generated in the process of recycling organic waste resources may be used without particular limitation.

The liquid manure used in the present invention contains all of nitrogen, phosphorus, and potassium, and the total amount thereof is 0.45% by weight or more, which is significantly higher than the standard value of 0.3% by weight, and does not contain harmful heavy metals such as arsenic, cadmium, mercury and lead. It may not be.

Such liquid manure contains a large amount of nitrogen, phosphorus, potassium, etc., so when used as fertilizer, it can effectively improve the growth of crops, but there is a problem that it is difficult to use in the actual field due to the odor generated by a large amount of nitrogen. In the present invention, by providing a natural organic complex fertilizer in which natural mineral powder and useful microorganisms are mixed together with liquid manure, it is intended to remove odors caused by liquid manure and improve usability and handling properties.

The liquid manure contained in the natural organic complex fertilizer is preferably included in the volume range of 25 to 55% by volume.If it is contained in less than 25% by volume, it is difficult to obtain the effect of improving the growth of the crops due to the liquid manure, and 55% by volume. If it is exceeded, the efficiency of removing odor is reduced due to excessive liquid manure.

As described above, natural mineral powder and useful microorganisms are used together to remove the odor of liquid manure. At this time, when mixing only natural mineral powder or only useful microorganisms, the efficiency of removing odor is significantly lowered, so it is preferable to mix the natural mineral powder and useful microorganisms together.

The natural mineral powder is a powder of a natural mineral containing a rare earth element in a trace amount, and the natural mineral powder may be preferably a natural feldspar powder, or a powder of a natural feldspar group, more preferably , It may be a natural feldspar powder containing about 1 to 3% by weight of rare earth elements. As such, the content of rare earth elements in the natural feldspar powder is low, so the amount of radiation generated from the feldspar powder is very low, about 0.02 μSv/hr, which is safe for the human body.

Since the rare earth elements contained in the natural mineral powder prevent acidification of the soil through a reducing action, and increase the absorption rate and utilization efficiency of fertilizer, there is an effect of reducing water pollution by reducing the amount of fertilizer used and nutrient loss. . In addition, it can reduce the use of pesticides by improving the immune function of crops, and because it has the function of decomposing residual pesticides contained in agricultural products, the main issues of eco-friendly agriculture, such as reduction in production, control of pests, nutrient imbalance, and decline in marketability, etc. There is an advantage that can effectively solve the problem of

It is preferable that the content of natural mineral powder is 24 to 45% by volume, but if it is less than 24% by volume, it has the effect of removing odors from natural mineral powders, improving fertilizer efficiency by the rare earth elements contained in natural mineral powders, and improving soil. This is because it is difficult to obtain, and when it exceeds 45% by volume, there is a problem that the content of the liquid manure is relatively small, and the performance as a fertilizer is deteriorated.

It is preferable that the natural mineral powder has a particle size distribution of 500 to 2,000 mesh.When it is within this particle size range, the dispersion degree of the natural mineral powder in the natural organic compound fertilizer is stably maintained, and when used in the actual field, the natural mineral powder The effect of improving fertilizer efficiency may be higher.

The useful microorganisms are added together with natural mineral powders to remove odors of liquid manure, and exhibit effects such as not only removing odors, but also preventing acidification of soil and increasing resistance to pests and pests of crops.

Useful microorganisms can be included in the volume range of 15 to 46% by volume, but when contained in less than 15% by volume, the effect of removing odor from liquid manure by the useful microorganisms is insignificant, the effect of improving the growth of crops decreases, and exceeding 46% by volume. When included, the content of liquid manure and natural mineral powders are relatively reduced, so the efficiency of removing odors of liquid manure is lowered, and the effect of improving the growth of agricultural crops due to liquid manure may be reduced.Therefore, 15 to 46% by volume in natural organic compound fertilizers It is preferably included as.

Useful microorganisms include at least one or more microorganisms selected from the group consisting of yeast, lactic acid bacteria, photosynthetic bacteria, actinomycetes, and filamentous bacteria, and may preferably include all of them.

As a useful microorganism, a culture solution obtained by culturing at least one or more of the above 5 microorganisms using a carbon source such as stevia, sugar or molasses is used, or only microorganisms in the lower layer obtained by centrifuging the culture solution, or the lower layer Useful microorganisms obtained by lyophilizing the microorganisms of may be used.

At this time, the inoculation concentration of the microorganism used to prepare the culture medium of the useful microorganism, the content of the carbon source, the culture environment and the period are not particularly limited, and at least one or more of yeast, lactic acid bacteria, photosynthetic bacteria, actinomycetes and filamentous bacteria as useful microorganisms Useful microorganisms to be included can be used, or commercially available microorganisms can also be used. Preferably, useful microorganisms including all of yeast, lactic acid bacteria, photosynthetic bacteria, actinomycetes and filamentous bacteria may be used.

Yeast bacteria are microorganisms that produce substances useful for crop growth by using secretions generated from the roots of crops and amino acids, sugars and soil organic substances released by photosynthetic bacteria.In particular, physiologically active substances such as gibberellin, a hormone that promotes plant growth. It activates plant cells, promotes plant root cell division, and helps proliferation of lactic acid bacteria and filamentous fungi.

As the yeast, for example, Saccharomyces cerevisiae, Candida utilis, etc. may be used, but is not limited thereto.

Lactobacillus uses sugars generated from photosynthetic bacteria and yeast bacteria to produce lactic acid with strong bacteriostatic power to inhibit the reproduction of harmful microorganisms and rapid decay of organic matter, and decompose proteins into amino acids in anaerobic conditions. In addition, it solubilizes non-degradable organic substances such as lignin and cellulose, ferment-decomposes organic substances, and inhibits the growth of fusarium, which is the main cause of serial disturbance.

Lactobacillus plantarum (Lactobasillus plantarum), Rhodobacter sphaeroides, and the like may be used as the lactic acid bacteria, but is not limited thereto.

Photosynthetic bacteria use light and heat as energy sources and can promote plant growth and growth by biosynthesizing secretions, organic substances, and harmful gases generated from the roots of plants into amino acids, nucleic acids, physiologically active substances, and sugars. It increases the diversity of the microflora and can prevent acidification of the soil due to its high antioxidant effect.

In addition, it can help the survival and proliferation of useful microorganisms by generating the necessary substrate so that the useful microorganisms can continuously proliferate, and it coexists with organic nutrients such as yeast and lactic acid bacteria, and also plays a role of fixing nitrogen.

Photosynthetic bacteria may include, but are not limited to, chlorobium of green bacteria, chromatium of yellow red bacteria, rhodospirillium of non-yellow red bacteria, rhodopsendomonas, etc., but are not limited thereto, improving soil quality, promoting plant growth, and survival rate of useful microorganisms And photosynthetic bacteria having an effect of improving the growth rate and the like may be used without particular limitation.

Actinomycetes are microorganisms having an intermediate form between bacteria and fungi, and may include, for example, microorganisms of the genus Streptomyces, but are not limited thereto.

Actinomycetes suppress the proliferation of harmful microorganisms by generating antibacterial substances such as streptomycin using amino acids produced by photosynthetic bacteria, and create an environment in which useful microorganisms are advantageous. In particular, since amino acids produced by photosynthetic bacteria are mainly used, the bacteriostatic effect can be remarkably improved when used together with photosynthetic bacteria.

Filamentous fungi are microorganisms having an effect of preventing the occurrence of harmful insects such as maggots, and, for example, microorganisms of the genus Aspelgirus may be included here, but are not limited thereto.

In the natural organic complex fertilizer of the present invention, a dispersant may be included in a volume range of 0.5 to 3.0% by volume, and the dispersant is included, thereby improving the degree of dispersion of the natural mineral powder, thereby preventing the natural mineral powder from sedimentation.

The material used as the dispersant is not particularly limited, and preferably, a dispersant with no or low toxicity to the ecology or human body approved by the FDA may be used. For example, at least one or more selected from the group consisting of PPG-9-ethylhexeth-5, polyethylene-polypropylene glycol, and sodium dodecyl diphenyl ether disulfonate may be used.

In particular, PPG-9-ethylhexeth-5 and polyethylene-polypropylene glycol are easily biodegradable substances, so before using natural organic complex fertilizers, the dispersibility of natural mineral powders is improved, and natural organic complex fertilizers are used in soil and crops. After spraying, it is rapidly biodegraded to minimize problems such as soil pollution or crop growth degradation due to a chemical component of a dispersant, and it is more preferable to use at least one of them as a dispersant.

The dispersant is preferably used in an amount of 0.5 to 3.0% by volume in the natural organic complex fertilizer.If it is used in less than 0.5% by volume, it is difficult to improve the dispersibility of the natural mineral powder, and if it exceeds 3.0% by volume, additional natural Since there is no effect of improving the dispersion degree of the mineral powder, the performance as a fertilizer of the natural organic complex fertilizer is rather deteriorated, and thus it is preferably included within the above-described volume range.

Meanwhile, another embodiment of the present invention relates to a method of manufacturing a natural organic complex fertilizer, and since the natural organic complex fertilizer is the same as described in an embodiment of the present invention, a duplicate description will be omitted.

The method of manufacturing a natural organic complex fertilizer comprises the steps of obtaining liquid manure by anaerobic or aerobic fermentation of organic waste resources; A pulverizing step of pulverizing natural minerals containing rare earth elements to have a particle size distribution of 500 to 2,000 mesh; And 25 to 55% by volume of the liquid ratio; 24-45% by volume of natural mineral powder; Mixing step of mixing 15 to 46% by volume of useful microorganisms and 0.5 to 3.0% by volume of a dispersant; includes.

The step of obtaining liquid manure is a step of obtaining a liquid fertilizer by anaerobic or aerobic fermentation of organic waste resources.For example, food waste is digested under anaerobic conditions and obtained by separating only liquid components from the digested mixture, or It may be a step of obtaining liquid manure by injecting air or air and microorganisms together in the obtained liquid manure to make it ripen, but is not limited thereto.

The pulverizing step is a step of pulverizing a natural mineral containing a rare earth element, and pulverization is preferably pulverized so that the particle size distribution of the natural mineral is 500 to 2,000 mesh, and the pulverizing method is not particularly limited.

The mixing step, liquid ratio 25 to 55% by volume; 24 to 45% by volume of natural mineral powder containing rare earth elements; Mixing and stirring 15-46% by volume of useful microorganisms and 0.5-3.0% by volume of a dispersant. Preferably, liquid manure, oil-soluble microorganisms, and dispersant are first mixed and stirred to prepare a uniform mixture, and then added to natural mineral powder. It can be prepared by dividing the mixed solution into multiple times and adding and stirring the mixture. By being manufactured in this way, it is possible to prevent agglomeration of the natural mineral powder, and it is possible to prevent uneven distribution problems such as sedimentation of the natural mineral powder or floating on the mixed liquid.

At this time, the stirring time and the stirring speed may be set as preferable conditions for the mixture liquid in each step to have a uniform distribution, and in the present invention, this is not particularly limited.

Such a manufacturing process is preferably carried out in a temperature range of 10 to 45°C, and if it is carried out at a temperature outside the above range, the activity of useful microorganisms decreases, useful microorganisms die, or harmful microorganisms rapidly proliferate. Since the effect as a fertilizer may be lowered and an odor may be caused, it is preferable to perform it under the above-described temperature conditions, and in particular, it is more preferable to perform it in a temperature range of 20 to 40°C to prevent this more effectively.

It is preferable that the natural organic complex fertilizer, which has been manufactured through the above steps, is stored at a temperature of 10 to 45°C, more preferably at a temperature of 20 to 40°C.

The natural organic complex fertilizer of the present invention promotes the synthesis and photosynthesis of chlorophyll, promotes root development and nutrient absorption, improves adaptability to a malignant environment such as drought or low temperature, strengthens resistance to various diseases and pests, improves the nitrogen utilization rate of plants, and remains of agricultural products. It can improve the productivity and quality of crops by reducing the concentration of pesticides, improving storage properties, and improving sugar content. In addition, there is an eco-friendly advantage because it improves the soil and improves the absorption rate of useful components of plants, thereby reducing the amount of use of fertilizers and pesticides.

Hereinafter, a natural organic compound fertilizer according to an embodiment of the present invention is prepared, and specific actions and effects of the present invention are described through this. However, this is presented as a preferred example of the present invention, and the scope of the present invention is not limited according to the embodiment.

[ Manufacturing example ]

Anaerobic digestion of food waste, separating the liquid phase, and aeration to uniformly mix 500 ml of liquor manure, 200 ml of EMK EM undiluted liquid ^® (EMFarm) and 12 ml of PPG-9-ethylhexeth-5, a dispersant, at a temperature of 25℃. The mixture was mixed to prepare a mixed solution, and the mixed solution was added in small portions to 300 ml of natural feldspar powder having a particle size of about 600 mesh prepared in advance and stirred to prepare a natural organic complex fertilizer of Example 1 in which the odor was removed.

As the liquid manure, a liquid manure containing 0.29% by weight of nitrogen, 0.013% by weight of phosphoric acid, 0.22% by weight of potassium, 0.13% by weight of salt, 99.12% by weight of moisture and other metal components was used, and 2.3% by weight of rare earth elements as feldspar powder. Feldspar powder having a radiation dose of 0.02 μSv/hr was used.

[ Experimental example One]

First, each natural organic compound fertilizer having the blending ratio of Table 1 was prepared by using the same method as in Preparation Example.

ml Contrast Example 1 Comparative Example 1 Comparative Example 2 Liquid manure 500 500 500 500 Feldspar powder - 300 500 - Useful microorganism - 200 - 500 Dispersant - 12 17 -

Thereafter, each sample was put into a chamber in an ammonia atmosphere by 8 g, sealed, and the ammonia concentration was measured over time, and the results are shown in Table 2. In addition, 500 ml of each sample was put in an airtight container and stored for 2 weeks, and then the odor when the stopper was opened was confirmed, and the results are also shown in Table 2. At this time, the determination of the occurrence of odor was determined on the basis of the occurrence of a serious odor that is impossible to use (◎), the occurrence of a odor that is difficult to use (O), and no odor (X).

Referring to the experimental results in Table 2, in the case of Comparative Example 1 in which the liquid manure was mixed with long-soil powder, the ammonia removal efficiency was slightly better than that of the control example composed of only liquid manure, and Comparative Example 2 in which useful microorganisms were mixed in the liquid manure was compared. It can be seen that the ammonia removal efficiency is slightly better than Example 1, but the ammonia removal efficiency is significantly lower than that of Example 1, in which the ammonia concentration was significantly reduced to 10 ppm after 3 minutes of starting the experiment.

In addition, in the case of Example 1 after a predetermined period of time, no odor occurred, but a serious odor occurred in the control example, and comparative examples 1 and 2 were relatively less than the control example, but still not used. A difficult degree of odor occurred.

In other words, it was confirmed from this experiment that both the feldspar powder and the useful microorganisms were added to the liquid manure to quickly remove both the odor generated from the liquid manure and the odor generated from the outside.

[ Experimental example 2]

After preparing a natural organic compound fertilizer in the same manner as in Preparation Example by applying the mixing ratio of Table 3, the same experiment as in Experimental Example 1 was performed, and the results are shown in Table 4.

Looking at the experimental results in Table 4, in the case of Examples 1 to 3, the odor removal effect was excellent, but in the case of Comparative Example 3 and Comparative Example 4, the initial ammonia removal rate was also low, and an odor was generated even after storage for 2 weeks. Was confirmed. In the case of Comparative Example 3, the content of the feldspar powder was judged to be insufficient, and in the case of Comparative Example 4, the content of the feldspar powder to the liquid manure was excessive, and thus a uniform mixture was not formed.

Therefore, from the results of this experiment, it was confirmed that the feldspar powder in the natural organic complex fertilizer is preferably contained in an amount of 24 to 45% by volume.
