Description

[0001] The present invention relates to an industrial-grade fertilizer containing an organic acid, an organic acid,

The present invention relates to an acid fertilizer containing an acidic fraction and a shell powder and an eco-friendly fertilizer containing the burned residue (burned material, combustible slag) thereof, It is possible to provide fuel with high energy efficiency and economical efficiency by using it, and the residue (burned material) remaining after burning it is contained in suitable ratio of nitrogen, phosphoric acid, potassium, magnesium and calcium components and is useful as an environmentally friendly fertilizer have.

Generally, general compost that has been used for a long time has compost of livestock such as swine, stalks, and udon. Generally, farmers use chemical fertilizer with general compost. However, it is a well known fact that as the use of chemical fertilizers increases, the fertility of land gradually decreases, the amount of fertilizer absorbed by crops decreases, and soil and water quality become contaminated. According to the statistics of the National Statistical Office in 2011, the number of Korean beef cattle in Korea is estimated to be 3.14 million. Comparing various fuel prices and calorific values, the unit price per 1,000 kcal is 248 won for gasoline, 151 won for boiler kerosene, 201 won for diesel fuel and 70 won for ozone fuel. It is a very economical energy source.

On the other hand, calcium is needed for crop cultivation. Calcium is an essential component of cell growth such as cell division, expansion, persistence of cell osmosis, and cell membrane enrichment, and it makes them resistant to disease. It also helps to regulate nutrient uptake and fluidity, prevent crop aging and maintain a healthy condition. It can help root growth and prevent the production of ethylene gas during fruit storage, which can enhance storage stability. It is necessary to supply an adequate amount of calcium to the soil. Because of the increase of soil porosity due to the supply of calcium, breathability and water content are improved. Improvement of soil physical property improves root respiration to improve drought and wintering, So that the crops can absorb and move these nutrients well. It also promotes decomposition of organic matter and activates mineral nutrients in the soil. In the absence of calcium, symptoms appear from the root, cork layer is formed in the root epidermis, root development becomes short and thick because the hair growth is not done properly. In addition, leaf tissue and leaf edge are dry, and cracks begin to appear, and cracks begin to appear. Deep belly rot, water trickling phenomenon, leaf sag and shoulder drop, deep and deepness, wetness and black deepness, browning phenomenon, winds, And corruption and malfunction of (fruit).

Calcium deficiency is likely to occur in the same climate and soil conditions as in Korea. Especially in the months of July and August when the crops grow vigorously, the long rainy season and the heavy rain caused the excessive rainfall, , The roots are less vigorous and cause calcium deficiency in crops. On the contrary, drought and dryness cause the crops to be unable to absorb calcium due to lack of calcium dissolution and migration.

On the other hand, when the strong acidity ratio between pH 4 and 5 is lowered, they bind to calcium in the soil to form salts or leach, resulting in a shortage of calcium to supply nutrients to the crops. In addition, unlike other nutrients, calcium does not play a role of supplementation when the lack of calcium in the fruits or leaves causes the calcium to be lacking in other parts such as the stem. As described above, calcium is liable to be leached, easily salted, has a limited absorption range, and has a property that it is difficult to move in the body. Therefore, it is necessary to use calcium chloride, The rice mulching can be covered with rice straw or hayashi, and circulation of cold water can be performed using the underground heating system.

Meanwhile, the number of farmers suffering from the inappropriate use of oyster shells is increasing. It is estimated that the shell from the oyster farm is about 270,000 tons per year in Korea. About 10% of the shells are used for agriculture as fossil fertilizer, That is, about 240,000 tons of shells are estimated to be lost or abandoned. Oyster shells consist of 92.08% calcium carbonate, 4.7% inorganic and 2.51% organic matter. However, when the oyster shells are crushed and sprayed on agricultural lands, there may be a problem of trace element deficiency and imbalance of the component proportions required for the crops.

In fact, after soil was collected from a field in a large amount of oyster shells, the soil component was analyzed to be pH 7.8, which is far higher than the appropriate standard of pH 6.0 to 6.5, indicating that it is likely to cause trace element deficiency. The content of calcium and magnesium, which greatly influenced the growth of crops, was also significantly increased when the plant (greenhouse) was grown. The magnesium content was similar to the appropriate standard of 1.5 ~ 2.0 Cmol / kg, And a standard of 18.0 Cmol / kg exceeding 5.0 to 6.0 Cmol / kg. The proper ratio of these two components is 4: 1 (calcium: magnesium), which is 12: 1, and trace element deficiency due to nutrient imbalance may occur. Therefore, in order to use oyster shell as fertilizer, it should be processed in the form of fossil fertilizer.

Phosphate fertilizer is a fossil fertilizer produced by calcining and grinding a fossil stone over a period of more than one year at a high temperature of 700 ° C or higher. However, such a feldspar fertilizer has a disadvantage in that the treatment efficiency is lower than the investment cost, since it is required to undergo a calcining and grinding process at a high temperature of 700 ° C or higher in the production.

In the United States, the use of antibiotics for the purpose of livestock growth and disease prevention is estimated to be between 900 and 1,300 million kg per year. Large amounts of antibiotics consumed by livestock are excreted as animal feedstocks and are generally supplied as nutrients for crops, so food crops are grown on soils exposed to antibiotics.

According to researchers at the University of Minnesota, the growth of three food crops, corn, lettuce, and potatoes, on soil with a liquid hog manure containing sulfamethazine, And the antibiotic concentration was also increased in plant tissues. Antibiotics have also been found to be very susceptible to contamination by antibiotics, such as potatoes, carrots and radishes, which are directly contacted with the soil, These antibiotic-contaminated plants are likely to cause allergic reactions in sensitive populations, such as children and the elderly, and can lead to antibiotic resistance, which can reduce the efficacy of antibiotics and cause serious problems.

Although the use of synthetic fertilizers is often used as a major source of crop nutrients in the production of organic crops, the use of synthetic fungi is a problem because of the possibility of damaging the health of animals consuming crops, including humans, due to the presence of antimicrobials. Therefore, it is necessary to provide eco-friendly fertilizer that can utilize the fossil resource more safely.

In the present invention, it has been proposed to provide a high-efficiency energy source and environmentally friendly fertilizer by recycling the most abandoned flour and shell resources, and it is possible to manufacture an axial fuel chip containing a certain proportion of flour and shell, And the post-combustion residues, incinerated residues, contain safe, appropriate proportions of nitrogen, phosphoric, potassium, magnesium and calcium components and are safe for use as fertilizers. It can be used as an effective eco-friendly fertilizer.

The inventor of the present invention has made it possible to utilize the starch, which is one of the main pollutants causing disposal and environmental pollution, as fuel, and by using the calcium in the shell as fertilizer, It is possible to provide an environmentally-friendly fertilizer containing the incineration residue (soft material), thereby completing the present invention.

The combustion fuel chip according to the present invention can provide energy at low cost by burning it, and the incineration residue, which is a post-combustion residue, can be safely and safely contained in the flue gas, and the proper proportions of nitrogen, phosphoric acid, potassium, magnesium, And can be used as an effective eco-friendly fertilizer by containing calcium in a form that can be used as fertilizer.

The present invention relates to a concentrated fractional fuel chip comprising a starch and shell powder at a weight ratio of 1: 0.01 to 0.2, in particular, a weight ratio of starch and shell powder of 1: 0.05 to 0.2, more specifically, Wherein the weight ratio of the shell powder to the shell powder is 1: 0.1 to 0.2. It is possible to derive a plurality of experimental results that the ratio of the contents of nitrogen, phosphoric acid, potassium, magnesium and calcium in the incineration residues of the axial fuel chips at the above mixing ratios can be optimized. Further, if the content of the shell powder is too large, there is a fear that the utility as a fuel chip is deteriorated.

In one embodiment according to the present invention, the manure can be used as the manure. In case of using cattle manure, the content of cellulose, lignin, organic matter and potassium is high and the contents of inorganic substances such as nitric acid, phosphoric acid, calcium and magnesium tend to be low. Therefore, when used for crops, the damage to the crops is not better than that of pigs or flocks. Since the amount of pork in the feed is low in fibrin, lignin, starch, and protein, the organic matter content tends to be lower than that in the case of wu manure, but the content of nitric acid and phosphoric acid is higher. Do not overuse it, it is not suitable for fuel. Although the content of nitrogen, phosphorus, and calcium is high and decomposition is fast, the content of organic matter is relatively low, so the soil improvement function is weak. As it has almost the same effect with chemical fertilizer, excessive use can cause accumulation of soil salts and obstacles to crop growth, and it is unsuitable as fuel.

In another embodiment according to the present invention, the present invention relates to an eco-friendly fertilizer comprising the residue remaining after burning the above-mentioned fractional fuel chips, i.e., incineration residues (soft material).

In another embodiment according to the present invention, the present invention relates to a process for the preparation of a composition comprising: (a) immersing the shell in water to remove salt; (b) drying and then pulverizing the shell; (c) mixing the starch and shell powder; (d) molding the mixture of the starch and shell powder in the form of chips; And (e) burning the fractional fuel chips produced in step (d), wherein in step (c), the mixing ratio of the starch and shell powder is 1: 0.01 to 0.2, Is in a weight ratio of 1: 0.05 to 0.2, more specifically, a mixing ratio of starch and shell powder is 1: 0.1 to 0.2. It is possible to derive a plurality of experimental results that the ratio of the contents of nitrogen, phosphoric acid, potassium, magnesium and calcium in the incineration residues of the axial fuel chips at the above mixing ratios can be optimized. Further, if the content of the shell powder is too large, there is a fear that the utility as a fuel chip is deteriorated.

In one embodiment according to the present invention, energy can be obtained by incinerating the fractional fuel chips, and incineration residues (soft materials) are obtained, which can be used as environmentally friendly fertilizers.

In one embodiment according to the present invention, at the time of incineration of the axial fuel chip, it may be carried out at a temperature of 700 to 900 DEG C for 10 minutes to 1 hour. When the incineration temperature and the time range are used, the mixed fraction fuel chips can be appropriately incinerated to generate sufficient energy. As described above, by burning the fractional fuel chips, the antibiotic component in the feces can be destroyed to provide a safe fungus-shell fertilizer without antibiotics.
