On the other hand, serpentine is a rock deteriorated from basic olivine or fluorite, which contains little alumina, and is very rich in magnesia and has a hardness of 2.5 to 4, maintaining a relatively soft property. In addition to magnesium, it contains many useful ingredients that are absolutely necessary for our farmland.

However, even though it contains the above useful ingredients, it is not used at all as a fertilizer and is used only for industrial or building materials.

It is pointed out that serpentine has abundant reserves in Korea and can be easily collected and processed, but only selected parts are urgently improved in terms of efficient utilization of resources, with only a limited portion selected for the above purposes. .

In other words, by effectively utilizing various useful ingredients included in the serpentine in our farmland, it is urgently needed to find a way to apply it to agriculture in early time if it is possible to improve agricultural competitiveness and increase income and satisfy consumers. Is requested.

The mixed soil improver of the present invention is supplied to the farmers who grow grains in poor soil by using serpentine, which is a useful mineral, and has excellent taste and taste by supplying acidic alkalinity, promoting the growth of rice, and supplying rich nutrition. Rice is produced to provide mixed soil modifiers with serpentine as the main ingredient that both producers and consumers can satisfy.

According to an aspect of the present invention by mixing 93 to 95% by weight finely powdered serpentine, 4 to 6% by weight of calcium oxide (CaO) and 1% by weight of zinc oxide (ZnO) are mixed with serpentine which can be applied to agricultural land. It is possible to provide a mixed soil modifier as the main raw material. Hereinafter, preferred embodiments of the mixed soil modifier based on the serpentine according to the present invention will be described in detail. In addition, before describing the preferred embodiments of the present invention in detail, the characteristics and problems of the Korean soil and the serpentine will be described first. The soil of our country is about 70% of the matrix of weathered acidic rocks such as granite, granite gneiss and the like. It is rich in silicic acid and aluminum and silicon is poorly absorbed and tends to be low in lime and magnesium. These soils in Korea are rainy due to the climate characteristics under 90% acidic conditions, and precipitation is particularly concentrated in the summer, so soil loss and soil nutrients (minerals) are severely leached. To increase yields, fertilizers and nutrients must be supplied, but fertilizers and pesticides are abused, contaminating soil and water quality, and agricultural products produced from contaminated soil are also contaminated. In particular, the overuse of chemical fertilizers is causing serious problems of soil acidification, salt accumulation, deterioration of this chemical and eutrophication. In order to improve the problems of the soil itself for growing agricultural products, sodium (Na ⁺ ), magnesium (Mg ²⁺ ), Cationic minerals such as potassium (K ⁺ ), calcium (Ca ²⁺ ) and zinc (Zn ²⁺ ) are adsorbed on the soil to prevent acidification of the soil, increase the base content, preserve the soil, Helps breed and promote organic decomposition, soil adsorption, water purification and other methods. In particular, Korean soils are lacking cationic minerals, which causes obstacles due to various nutritional imbalances. Nevertheless, farmers misunderstand it as a disease and apply excessive pesticides. In addition, soil effective microorganisms are most active at pH 6.0 to 6.5, and in these weakly acidic conditions, effective microorganisms promote organic degradation to promote soil structure improvement. The national average and improvement goals for each component are listed. division PH (pH) Organic matter (%) Phosphoric Acid (ppm) Substituent Cation (cmol + / kg) Zinc (cmol + / kg) Effective silicic acid (mg / kg) weir magnesium calcium Proper range 6.0 3.0 100 0.27 2.0 5.5 2.0 130 to 180 Answer 5.6 2.5 128 0.32 1.2 4.0 1.0 72 (田) 5.5 2.4 538 0.64 1.3 4.2 1.2 - Improvement Goal 0.5 0.6 overabundance overabundance 0.8 1.5 One 58 to 108 Therefore, if the cationic minerals of magnesium, calcium, and zinc, except for phosphorus and potassium, which are already in excess in the soil, are adsorbed to the soil, the soil is alkalized (finally acidified) to help propagate effective microorganisms. By breeding such effective microorganisms, it is possible to solve the salt condensation of soil and soil pollution of sub-film, and to solve the nutritional imbalance of crops. The chemical composition of serpentine, the main raw material of the present invention, is 3MgO, 2SiO, 2H ₂ O. That is, hydrous magnesium silicate, the chemical composition and content of MgO 30 to 40%, SiO ₂ 34 to 42%, CaO 3 to 5%, Fe ₂ O ₃ 2 to 5%, Al ₂ O ₃ 0.5 to 1.8%, Ni It is found that 0.1 to 0.3%, Cr 0.3 to 1.7%, and lg Loss 11 to 13% contain a large amount of inorganic salts, and calcium, nickel and chromium are also contained in a small amount.

In addition, the serpentine was confirmed to have a radiation energy of 3.73 × 10 ² with 0.925㎛ irradiation at room temperature according to the far-infrared emissivity survey (Issuance No .: FIR to 111) of the Korea Institute of Construction Materials. It can help to absorb and transport minerals in the soil of crops, and contributes to reducing fertilizer fertilization. In addition, the far-infrared rays can improve soil contamination problems, such as regenerating soil contaminated by the activation of microorganisms, and also inhibiting the occurrence of bacteria and mold by antibacterial action. Concentrated on replenishing the soil with zinc. This is related to the fact that more than 85% of the fertilizers in use are mainly made up of nitrogen, phosphoric acid and galley. In other words, nitrogen, phosphoric acid and scalp are already showing excessive state in the soil and are causing problems such as nutritional bias. Soil improvers containing magnesium, calcium, and zinc are required to remedy this problem and to provide a balanced supply of cationic minerals to harvest a lot of good crops. In particular, since rice farming is grown in water due to its cultivation characteristics, it is necessary to supplement fertilizer with magnesium, calcium, and zinc in order to produce high quality rice due to severe base dissolution. These three minerals, which are most needed for crops, are also the three most important minerals for the person who is the end consumer of it. Among these, magnesium and calcium do not interfere with soil or crops even when over fertilized, and improve the quality and taste of the crops produced. Zinc quickly lowers the roots of young rice seedlings, activates the production factor of auxin, a plant growth regulator, synthesizes protein and starch, and aids nitrogen metabolism. Zinc deficiency is a phenomenon of yellowish whitening between the veins of plant leaves, which can be pale green, yellow or sometimes white. In addition, it is known that the lack of zinc causes the development of Grana in chloroplasts and simultaneously causes vacuoles. In particular, in the case of rice, iron, manganese, and the like inhibits the absorption of zinc, and zinc is absorbed by active metabolism, so low temperature or metabolic inhibitors are one factor that inhibits the absorption of zinc. As is already known, zinc may be toxic when excessive fertilization is required. Therefore, according to a preferred embodiment of the present invention, 93 to 95% by weight of finely powdered serpentine (CaO) 4 to A mixed soil modifier can be obtained by mixing 6% by weight and 1% by weight of zinc oxide (ZnO). Component contents of magnesium, calcium, and zinc in the mixed soil improver according to the preferred embodiment are described in [Table 2]. division Ingredient weight per kg (kg) Mg Ca Zn Mg content (%) Mg content (kg) Ca content (%) Ca content (kg) Zn content (%) Zn Component Content (kg) serpentine 93 to 95 30 to 40 27.9 to 38 3 to 5 2.79 to 4.75 - - Calcium oxide 4 to 6 - - 45 to 50 1.8 to 3.0 - - Zinc oxide One - - - - 70 to 80 0.7 to 0.8 Mixed ingredient content (kg) 100 27.9 to 38 4.59 to 7.75 0.7 to 0.8

According to a preferred aspect, the mixed soil modifier of the present invention may provide zinc to the soil which is not required to be contained in the soil even though it is a mineral required in the plant, which is poorly absorbed even if it is contained. Zinc is supplied from zinc oxide and contains between 0.7 and 0.8 kg of zinc in a 100 kg mixed soil modifier. As shown in [Table 1], the amount of zinc that is appropriate in order not to exceed the proper range of 2.0 cmol + / kg while supplying the soil with 1 to 0.8 cmol + / kg, which is the amount of the replaceable zinc cation required for Korean soil, is present. As described above, it is important to supply an appropriate amount because zinc is excessively supplied, but it is preferable to include 1% in the mixed soil modifier of the present invention. Preference is given to using with magnesium. However, only calcium contained in the serpentine is insufficient to provide the necessary amount of substitutional calcium ions in the soil shown in [Table 1], and thus calcium supply by calcium oxide is necessary. In addition, calcium is not as serious as zinc, even when over-supplied, so there is little problem. However, as already known, it is not preferable to include calcium oxide more than 6% by weight since calcium reduces the radiation and absorption of far infrared rays. Therefore, according to a preferred embodiment of the present invention, calcium oxide is preferably included 4 to 7% by weight. Serpentine among mixed soil modifiers is an important factor in the supply of magnesium and calcium. Serpentine can also supply minerals such as silicon, aluminum, iron, nickel and chromium. According to a preferred embodiment, the serpentine is most used because it can be easily obtained at a low price in the surroundings, is easy to process, and is rich in cationic minerals. Therefore, the more serpentine is contained in the mixed soil improver, the better. Therefore, by mixing 93 to 95% by weight of serpentine, except for the appropriate amount of zinc and calcium, it is possible to prepare a mixed soil modifier mainly composed of serpentine. According to a preferred embodiment, the mixed soil modifier of the present invention can be easily and cheaply in the vicinity. 93 to 95% by weight of finely powdered serpentine is prepared, and 4 to 6% by weight of calcium oxide (CaO) and 1% by weight of zinc oxide (ZnO) are mixed with a known mixer. Mixed soil modifiers can be obtained. The application of such mixed soil modifiers is preferably, but is not limited to, that the amount of application should be appropriately adjusted according to soil, climatic conditions or the type of grain. The mixed soil improver according to the present invention has the advantage that the soil improvement, crop increase and quality improvement can be achieved even at a small spread.

When the mixed soil improver of the present invention is sprayed onto the soil, the far-infrared rays emitted at the same time to promote the activation and maturation of microorganisms are very effective in promoting the growth of grains, which is useful for excellent rice cultivation.

In particular, magnesium enhances the taste of rice, which acts as an important factor in consumer decisions. When rice is grown with rice grown using the mixed soil improving agent of the present invention, the grains of rice are shiny, have excellent elasticity, and are unchanged. Can be maintained.

As described above, when the mixed soil modifier according to the present invention is applied to agriculture, the mixed soil modifier may be manufactured at low manufacturing cost. In addition, the mixed soil improver thus produced will be able to increase production by promoting the growth of rice, and rice with excellent taste and taste can be provided by supplying rich nutrients, which can contribute to efficient utilization of resources and income of farmers. . In addition, the most important minerals for crops, such as magnesium, calcium and zinc, can be supplied to the crops, and moreover, those who consume them can also supply insufficient minerals.
