Description

Environment-friendly organic liquid fertilizer and its manufacturing method {Environment- friendly organic liquid fertilizer and manufacturing method of the same}

The present invention relates to an environmentally friendly organic liquid fertilizer containing both organic and inorganic components by fermenting a mixture in which a carbon source is added to a nitrogen source with a microorganism, and a method for producing the same.

With the development of chemical fertilizers, farmers are using chemical fertilizers mostly for planting facilities such as plastic houses. Chemical fertilizers have the advantage of increasing the production of crops and artificially controlling fertilizer components, but they accelerate the acidification of soil and weaken the intellect, weakening the ability to withstand various diseases (viral diseases, etc.), which causes pesticide use.

Recently, the safety problem of agricultural products has emerged as an important social problem, and in particular, the need for environmentally friendly fertilizers is increasing due to side effects caused by chemical fertilizer abuse. Organic fertilizers are recommended to solve these problems, but organic fertilizers are used in the company's products because they are difficult to produce on their own and cumbersome to use, and each organic composting company uses unfermented compost as the main raw material. As it produces, there is a danger of damage to crops caused by gas such as ammonia, which is generated after using unfermented compost. Therefore, farmers avoid using organic fertilizers.

Examples of the raw material for producing the organic fertilizer include urea, lime nitrogen, bone meal, mortar, green manure, vegetable oil, fish and seaweed. In particular, algae extracts and seaweed powders contain not only various inorganic ingredients but also oxins and cytokinin, which are types of growth hormones, compared to organic materials obtained from land, and thus can be used as plant growth promoters or fertilizers. Can be. In addition, it can be expected to improve the air permeability by increasing the stability of soil entry due to the chemical properties of seaweeds, which is known to affect productivity and quality by improving the root zone environment of cultivated crops (Ho-Geum Ahn et al. ., J. of Korean society of Environmental Technology, 6 (3); 210-218, 2005).

On the other hand, traditionally used for growing crops, but recently, a method of managing seeds and seedlings through precise manure (chubby) management has been widely used. Especially in the case of high-quality farming, the manure during mid- and late-growth has become a very important management technique. Various agricultural spraying and irrigation materials are also changing from mantle management to manure management. In order to manufacture the liquid fertilizer used for manure, conventionally, a method of preparing by dissolving nutrients such as nitrogen, phosphoric acid, potassium, boron, magnesium, iron, etc., proposed by the fertilizer process specification, has been mainly used. As such, most of the manure fertilizers sold in Korea are chemical fertilizers, so fermented liquid fertilizers are used when environmentally friendly organic production certified farmers cannot manage their growth.

In addition, effective microorganisms (EM) were mixed with liquid microorganisms developed by a combination of 5 and 10 genus 80 beneficial microbial strains aimed at soil improvement and pest control by Professor Higa, a professor of agriculture at Ryukyu University, Japan in the 1980s. The mixed microorganism as a culture solution is composed of photosynthetic bacteria, lactic acid bacteria, yeast, actinomycetes and filamentous fungi. Useful microorganisms are anaerobic bacteria that can grow with or without oxygen. Photosynthetic bacteria obtain carbon sources from organic materials, energy is supplied from sunlight, lactic acid bacteria and yeast obtain carbon sources from organic materials, and oxidize organic compounds to oxidize energy. Get When useful microorganisms are inoculated in an environment where corruption is in progress or is expected to become corrupt, a fermentation environment is formed by generating antioxidant enzymes, antioxidants, amino acids, vitamins, sugars, organic acids, minerals, various enzymes and hormones, and thus oxidized conditions. It inhibits the growth of harmful microbial species, enhances the growth of beneficial microorganisms and at the same time eliminates the toxicity of harmful substances (Herias et al., Clin. Exp. Immunol., 116; 283-290, 1999).

The useful microorganisms (EM) can be used for the purpose of suppressing oxidation, decay and reducing activity throughout agriculture, forestry, animal husbandry, fishing, and the environment due to their functionality. In addition, it can be usefully used for techniques aimed at reducing odor, decomposition of harmful substances, and fermentation of by-products in composting and liquefaction of agricultural, livestock, and fishery by-products.

Patent 10-0333091 or 10-2010-0042824 discloses a method for preparing a liquid fertilizer based on blood powder decomposition solution. In this method, the enzymes, microorganisms or acids are used to decompose blood, and then the main components of fertilizers such as nitrogen, phosphoric acid, girly, goto, manganese, boron, iron, molybdenum, zinc, copper, and calcium are added to the blood decomposition solution. Prepare fertilizers. However, such additives are disadvantageous because they are produced by chemical methods and cannot be used as environmentally fertilizers.

In addition, Patent No. 10-0191396 discloses a method for preparing a liquid fertilizer using by-products obtained from animals. In this method, by-products obtained from animals are decomposed into alkaline compounds, such as potassium hydroxide or sodium hydroxide, and pancreatin, a digestive enzyme, and a conventional fertilizer additive is added to this digestion solution. However, this method also has a problem that the chemical additives.

Patent 10-1058245 discloses a method for preparing a liquid fertilizer using fish waste. In this method, the oil is removed from the fish waste and then cultured by adding a specific mixed microbial group. The liquid fertilizer produced by this method has a disadvantage that the essential elements necessary for growing crops are not included at an appropriate level, and to compensate for this, chemical additives must be added.

Accordingly, it is an object of the present invention to provide a method for producing an environmentally friendly liquid fertilizer containing evenly inactive ingredients when preparing an organic liquid fertilizer obtained by fermenting a mixture in which a carbon source is added to a nitrogen source as a useful microorganism.

It is another object of the present invention to provide a method for recycling waste comprising protein and waste comprising carbohydrates.

The present invention focuses on the fact that the fermentation broth with different compositions of inactive ingredients is produced when fermenting with microorganisms after mixing the nitrogen and carbon sources in different ratios to adjust the inactive ingredients by mixing the fermentation broths with different compositions. The method was devised. In addition, the fermentation broth may be prepared by varying the composition of the inactive ingredient by changing the type of carbon source, or the fermentation broth containing the components of the seaweed may be prepared by further adding fermentation of seaweed in addition to the nitrogen source and the carbon source. In this case, if there is a solid material among the materials, a process of pulverizing the solid material and adjusting the hydrogen ion concentration (pH) and then decomposing with a degrading enzyme may be added.

It is possible to produce completely environmentally friendly liquid fertilizers by using electrolyzed water or lye instead of chemicals when adjusting the pH of the ground or fermentation broth. In particular, since the mineral composition varies depending on the type of electrolyte added when preparing the electrolyzed water, it is also possible to control inactive ingredients by using a process of adjusting pH. Lye can also control inactive ingredients by adjusting the pH, since the composition of the ingredients varies depending on the material from which the lye is produced.

The present invention has the effect of providing an environmentally friendly organic liquid fertilizer manufacturing method containing the organic and inorganic evenly required for plant growth.

In addition, the present invention has the effect of recycling agricultural, livestock, fishery by-products containing a large amount of protein, carbohydrate components.

Squares on a white background show the process of material change and squares on a gray background show the manufacturing process. Dotted squares and arrows indicate conditional manufacturing processes that can be added if necessary.
Figure 2 is a result of experimenting on the fertilizer effect of fermentation broth fermented with useful microorganisms (EM stock) by mixing the squid meat hydrolyzate and molasses in five ratios in the embodiment of the present invention.
Figure 3 in the embodiment of the present invention mixed the squid meat hydrolyzate and molasses in a ratio of five different fertilizer effect of fermentation broth fermented with useful microorganisms (EM stock solution) after testing the cabbage seedlings ground and underground weights It is shown in the graph.

In the present invention, the nitrogen source and the carbon source are mixed at different ratios, respectively, and the mixture is fermented into useful microorganisms, thereby inducing the difference in the components of the fermentation broth according to the mixing ratio of the carbon source and the nitrogen source. The liquid fertilizer was prepared using the fermentation broth with different composition of the above as the test material. The fermentation broth obtained in the manufacturing process is used as a fertilizer directly as a fertilizer or by mixing fermentation broths with different compositions to prepare an organic liquid fertilizer having a variety of fertilizer components in an environmentally friendly manner.

The nitrogen source may be a variety of meat, slaughterhouse waste, fish processing by-products, fish waste, milk, soybeans, the carbon source may be used in various cereals, molasses, corn, rice bran, rice straw, sugar cane. In addition, seaweeds can be added to diversify ineffective ingredients, and seaweeds that can be added can use seaweed, kelp, seaweed, and starfish.

In the case where the nitrogen source and the carbon source are in the solid state, it is preferable to use the pulverized product to accelerate the decomposition and the fermentation rate. In addition, to accelerate the fermentation rate, it is preferable to hydrolyze the pulverized nitrogen source and carbon source before the fermentation process. The hydrolysis of the nitrogen source or carbon source may be a chemical substance such as an acid or an alkali, but it is preferable to use an enzyme for producing an environmentally friendly organic liquid fertilizer for the purpose of the present invention. As the hydrolase that can be used in the present invention, any one of proteolytic enzymes of Alkalase, Flavorzyme, Neutrase, and Protamex may be used for the nitrogen source, and the carbohydrate decomposing enzyme of amylase or cellulase may be used for the carbon source.

It is important to adjust the optimum pH for the treatment of the hydrolase. The pH adjustment may use hydrochloric acid or potassium hydroxide, but in order to produce an environmentally friendly liquid fertilizer for the purpose of the present invention, it is preferable to use acidic electrolytic water or alkaline electrolytic water. The electrolyzed water may be prepared using an electrolysis method by adding an electrolyte to water. When the electrolysis is performed, a basic solution is generated by the OH- ion at the (-) pole and H + ions are produced at the (+) pole to generate an acidic solution. The solutions are alkaline electrolyzed water (alkaline reduced water) and acidic electrolyzed water, respectively. Natural acids such as fermented vinegar or lye may be used in place of the acidic or alkaline electrolyzed water.

Fermentation of the nitrogen source and the carbon source in the organic liquid fertilizer manufacturing process of the present invention may be used by mixing a variety of microorganisms commonly used in the fermentation alone or in a constant ratio, it is preferable to use effective microorganisms (EM).

Hereinafter, the specific contents of the present invention will be described in detail through preferred embodiments, but the scope of the present invention is not limited by the following examples.

< Example  1> the invention eco-friendly organic liquid fertilizer manufacturing

In order to prepare the organic liquid fertilizer according to the present invention, the composition change experiments were carried out according to the ratio of nitrogen and carbon sources. In this example, squid meat was used as the nitrogen source and molasses extract was used as the carbon source. Fermentation of the nitrogen source and carbon source used EM stock solution, which is a useful microorganism product. Molasses extract and EM stock were purchased from Ever Miracle (Jeonju, Korea), and seaweed powder was made by drying dried seaweed seaweed inhabiting the east coast of Korea.

At a rate of 160 ml of water per 100 g of squid meat, it was ground with a cutter. NaOH was added to adjust the pH to 8 and water was added so that the amount of water finally added was 200 ml. 1 ml of Alcalase, a protease was added thereto, and the reaction was stirred for one hour at 55 ° C. 1 ml of Alcalase was added again and the reaction was stirred for 24 hours at 55 ° C. 1 ml of Alcalase was added thereto and the mixture was stirred at 55 ° C. for 24 hours.

The squid meat hydrolyzate and molasses in the extract state were mixed in different ratios as shown in Table 1 below. EM stock solution was added to the mixture and fermented at 35 ° C. for 19 days. Each fermented product obtained a supernatant after centrifugation, and analyzed the component difference of the organic liquid fertilizer of the present invention according to the mixing ratio of the nitrogen source and the carbon source by analyzing the components of the supernatant. Analysis of the components was carried out by the Plant Environment Control Laboratory, Department of Environmental Horticulture, Seoul National University.

On the other hand, in the case of Preparation Example 2 shown in Table 1, in addition to the squid meat hydrolyzate which is a nitrogen source and molasses extract which is a carbon source, seaweed dry powder was added to prepare a mixture. In Preparation Example 2, the effect of plant growth promoters such as oxins or cytokinins and other minerals contained in seaweed (seaweed) was examined.

As can be seen from Table 2 below, the organic liquid fertilizer of the present invention is acidic, so if necessary, the pH of the fermentation broth may be adjusted. Although chemicals may be used to adjust the pH of the fermentation broth, it is preferred to use alkaline electrolyzed water to produce environmentally friendly liquid fertilizers. Alkaline electrolyzed water (alkaline reduced water) has a different mineral content depending on the type of electrolyte added when making the electrolyzed water, so it is also possible to obtain an effect of controlling inactive ingredients depending on the method of making the electrolyzed water.

It is also possible to use natural bases such as lye instead of electrolyzed water. Lye is made from ash from plants, and minerals vary depending on the type of plant.

PH and EC of Organic Liquid Fertilizer of the Present Invention According to Mixing Ratio of Nitrogen Source and Carbon Source Experiment Production Example 1 Production Example 2 Production Example 3 Production Example 4 Production Example 5 Item Used equipment pH pH meter 3.79 3.73 3.78 3.74 4.05 EC (mS / cm) EC meter 17.96 20.20 22.00 15.83 18.25

As shown in Table 3, it can be seen that there is a difference in the composition of the organic liquid fertilizer depending on the ratio of the hydrolyzate and molasses and the additives. For example, in Preparation Example 2 in which seaweed powder was added, the content of nitrogen and potassium was decreased, but the calcium content was increased, compared to the organic liquid fertilizer of Preparation Example 1. The organic liquid fertilizer of Preparation Example 3, in which the squid meat hydrolyzate was added twice, had a large increase in nitrogen and phosphorus components compared to Preparation Example 1, while potassium, calcium, magnesium, iron, and manganese did not change significantly. On the other hand, in the case of Preparation Example 4, which was added by reducing the hydrolyzate in half, the nitric acid component was increased compared to Preparation Example 1, and potassium and calcium also increased. The organic liquid fertilizer of Preparation Example 5, in which the squid meat hydrolyzate was added 1.5 times and the molasses was added 3 times, the nitrogen component was significantly reduced than the components of Preparation Examples 1 to 4, but phosphorus, potassium, calcium, magnesium, iron, manganese and zinc The ingredients increased significantly.

< Example  2> Effect of the invention organic liquid fertilizer

Fertilizer effect experiment was performed on the five organic liquid fertilizers (Preparation Example 1 to Preparation Example 5) according to the present invention. As a test variety of this example, the representative varieties of leafy vegetables, cabbage (CR summer), were used. The cabbage seedlings were root-washed 20 days after planting, fixed in a hydroponic cultivation incubator, and examined the growth reaction while supplying the developed liquid fertilizer. The liquid fertilizer bioassay was carried out using a vegetable hydroponic incubator in a glass greenhouse, and the hydroponic cultivation was placed in a positive control and each fermentation broth in four replicates at a dilution rate of 1,000-3,000. The growth characteristics were examined by the number of leaves, leaf length, grass length, root length, tube, and live weight at 2 days intervals after planting.

As a result, as shown in Fig. 2, the growth rate promoting effect of both the ground portion and the underground portion of Chinese cabbage seedling by the liquid fertilizer of Preparation Example 3 was the most excellent. 3 is a graph showing the ground portion and the ground portion weight, it can be seen that the ground portion and the underground portion of the cabbage seedling treated with the organic liquid fertilizer of Preparation Example 3 evenly grow. The organic liquid fertilizer of Preparation Example 3 had a high nitrogen content and had an excellent effect for promoting nutrient growth. In addition, the organic liquid fertilizer of Preparation Example 5 has an excellent potassium content and is suitable as a fertilizer for reproduction of fruit and vegetable.

In the present invention, it can be seen that the difference between the ratio and the concentration of the nitrogen source and the carbon source in the organic liquid fertilizer manufacturing process greatly affects the composition of the fertilizer component. In addition, the type of nitrogen source and carbon source may also have a significant effect on the composition of the inactive ingredient, and fermentation broth containing the components of the seaweed may be prepared by adding fermentation of seaweed in addition to the nitrogen source and carbon source. Therefore, it is possible to prepare a liquid fertilizer using a fermentation broth having an inert ingredient composition suitable for the purpose among these fermentation broths, and furthermore, a liquid fertilizer having a desired composition may be prepared by mixing fermentation broths having different compositions.

Furthermore, it is possible to produce fully environmentally friendly liquid fertilizers by using electrolyzed water or lye instead of using chemicals to adjust the pH of the mill or fermentation broth. In particular, since the mineral composition varies depending on the type of electrolyte added when preparing the electrolyzed water, it is also possible to control inactive ingredients by using a process of adjusting pH. Lye can also control inactive ingredients by adjusting the pH, since the composition of the ingredients varies depending on the material from which the lye is produced.

Unlike the conventional method, the preparation method of the present invention produces an organic liquid fertilizer having an optimal inactive ingredient composition in a completely environmentally friendly manner without using any chemicals in all processes.

The present invention has the effect of providing an organic liquid fertilizer containing organic and inorganic materials composed of different components and fermentation using a useful microorganism after mixing the nitrogen source and the carbon source in different ratios, respectively, and the method It is a very useful invention for the fertilizer industry and environmental industry because it has an excellent effect of recycling the marine by-products.
