Today, the cultivation of the crops by the facilities such as the vinyl houses and the specialized farming of the area are increasing day by day. Specialized agriculture and habitat cultivation in this area lead to serial cultivation, and there are many problems in the sequencing due to accumulation of soil salts due to the series.

In other words, salt accumulation occurs in the soil due to repeated cultivation of the same crops. In order to solve the accumulation of salts, the crops are cultivated while they are transferred. However, the crops can not be rotated in areas where the agricultural lands are limited. Fertilizer, etc.) to reduce the accumulation of salts. However, due to the lack of labor force, there is a limit to the production of compost. In the case of organic fertilizer, too, there is a limit to the elimination of salts in repeated series.

In addition, excessive use of chemical fertilizers to increase the productivity of crops, even if the crop rotates, increases the acidification and eutrophication of the soil, resulting in poor growth of the crops and weakening of the immune system.

As a result, resistance to insect pests and resistance to crops is reduced, resulting in a greater amount of pesticide and chemical fertilizer being sprayed, and pesticides remain in the agricultural products produced in such soil, thereby deteriorating the public health and reducing the yield.

In addition, the number of microorganisms that are the basis of soil organic matter and volatility has been drastically reduced due to soil pollution and destruction of environment caused by accelerated mechanization and industrialization.

Various methods for activating or improving the existing soil have been attempted in order to solve these problems and utilize the sustainable soil production capability.

Charcoal is known to have excellent soil improvement effect. In particular, it is important to neutralize the acidified soil by adsorbing the pesticide or chemical fertilizer components which remain in the soil to acidify the soil, as well as to absorb the heavy metals present in the soil and insolubilize them to prevent the risk of heavy metals And the anions or far infrared rays generated from the charcoal itself act to restore the soil ecosystem by activating the microorganisms in the soil.

Hereinafter, a soil remediation agent using charcoal and lime algae according to a preferred embodiment of the present invention, a method for producing the same, and a horticultural soil and horticultural soil mixed therewith will be described in detail.

The soil conditioner according to one embodiment of the present invention is prepared by mixing char and permeate. For example, 0.1 to 10 parts of the penetration liquid may be mixed with 100 parts of charcoal.

In the present invention, the permeate is absorbed by the char and infiltrated into the innumerable pores formed inside the char. Therefore, since the permeate has a slow releasing effect in the soil for a long period of time, the soil improvement effect can be sustained for a long time.

Charcoal remains in the soil to neutralize the acidified soil by adsorbing the pesticide or chemical fertilizer components that acidify the soil, as well as adsorbing and insolubilizing the heavy metals in the soil and the danger of heavy metals that can accumulate in the human body through the crop And the anions or far-infrared rays generated from the charcoal itself act to restore the soil ecosystem by activating the microorganisms in the soil. In particular, since charcoal is a porous structure formed with innumerable pores, it has excellent microbial adsorption power, inhibits fermentation of anaerobic bacteria in the soil, and enables oxygen supply to the roots of crops. In addition, the porous material itself absorbs moisture to regulate the moisture content in the soil.

Charcoal can be used to burn wood such as oak charcoal and bamboo charcoal. The char is preferably a powder having a size of 0.1 to 2 mm. When a powder of too small size is used, the absorption amount of the permeating liquid is lowered, so a size of 0.1 to 2 mm is suitable.

The penetration liquid may be formed by mixing a lime algae powder with water as an example.

Calcareous algae are algae that settle lime on the body. These lime algae include algae, red flora, and southern plants. In particular, lime birds can use coral reefs with coral horns. Coralia officinalis ( Coralia officinalis ) absorbs the minerals and nutrients of the sea, forming the outer wall of thick calcium carbonate on the surface of the body.

The lime algae are dried by applying hot air at 100 to 300 ° C and then finely pulverized and powdered. For example, it may be pulverized to a size of 0.1 to 50 mu m. Crushed lime algae are mixed with water to make permeate. 0.1 to 10 parts by weight of lime algae powder may be mixed with 100 parts by weight of water.

Calcium carbonate (CaCO ₃ ), a major component of lime algae, is a component of the cell membrane and has the effect of strengthening the plant and promoting the growth of roots and leaves. In addition, it neutralizes the acidic soil and corrects the soil reaction, thereby promoting the activity of the soil microorganism, and plays an excellent role in improving the soil environment suitable for plant growth. It also acts as an antagonist to suppress excessive absorption of nitrogen assimilation, magnesium, gall and sodium, and improves circulation of air and moisture in the soil. Also, the lime algae powder strengthens the mineral component of the permeate.

Meanwhile, in order to improve the functionality of the penetrant, the present invention may be combined with 0.1 to 5 parts by weight of the lime algae powder and 1 to 10 parts by weight of the antler extract, based on 100 parts by weight of water.

Sagina japonica is a year-old or a biennial plant that grows in fields, roads, and creeks , and increases the antimicrobial activity of the permeate .

The ants extract can be extracted by adding an extraction solvent to the ants. As the extraction solvent, at least one selected from water, a lower alcohol having 1 to 4 carbon atoms, a polyhydric alcohol, or a mixture thereof may be used. As the lower alcohol having 1 to 4 carbon atoms, methanol, ethanol and the like can be used. As the polyhydric alcohol, butylene glycol, propylene glycol, pentylene glycol and the like can be used. Mixtures of water and lower alcohols, mixtures of water and polyhydric alcohols, mixtures of lower alcohols and polyhydric alcohols, or mixtures of water and lower alcohols and polyhydric alcohols can be used as the mixture.

As an example of the extraction, 5 to 20 times of the extraction solvent may be added to the antiserum at a weight ratio, and then hot water extraction, cold extraction, hot extraction or the like may be used at 20 to 150 ° C for 4 to 30 hours. After extraction, the solid residue is removed by filtration to obtain a liquid extract.

The soil improving agent of the present invention can be obtained by mixing the permeating liquid and the char so that the permeating liquid can be absorbed by the char.

100 parts of charcoal, 0.1 to 10 parts of penetration liquid to the skin, and the mixture can be mixed using a stirrer. Upon mixing, the permeate is absorbed through the surface of the char and penetrates into the pores.

Since the permeate is absorbed on the surface of the charcoal of the porous structure and inside the pores, there is no fear of loss, resistance to the change of the soil environment, and improvement of the rhizosphere environment around the root of the crop.

A method for producing the soil conditioner of the present invention will be described.

First, lime algae are dried by applying hot air at 100 to 300 DEG C, and then pulverized to a size of 0.1 to 50 mu m. And 0.1 to 10 parts by weight of lime algae powder are mixed with 100 parts by weight of water to obtain a permeate.

An injection nozzle (40) for injecting a penetrating liquid at a predetermined interval is provided on the outer peripheral surface of the rotary shaft (20). The injection nozzle (40) communicates with the inner space of the rotary shaft (20). Therefore, the penetrating liquid flowing into the inside of the rotary shaft 20 is blown into the housing 10 through the ejection holes 45 formed in the ejection nozzles 40.

When the rotary shaft is rotated by the operation of the electric motor, the charcoal introduced into the housing 10 moves in the direction of the discharge port 17 of the housing by the stirring blades. At this time, the penetrating liquid ejected through the injection nozzle 40 is mixed with the char. Charcoal mixed with the permeate is discharged through the discharge port (17).

In another embodiment of the present invention, the soil conditioner may further contain mixed minerals. For example, 100 parts of charcoal may be mixed with 0.1 to 10 parts of a penetration liquid and 0.01 to 2 parts by weight of mixed minerals to obtain a soil conditioner.

Minerals are minerals and minerals that are essential for the growth of plants and are essential nutrients for plant growth. Mineral strengthens the stalks and leaves of the plant and increases disease resistance. The present invention uses mixed minerals in which various kinds of minerals are mixed to strengthen the minerals of the soil conditioner.
