Description

Eco-restored greening method using eco-friendly greening composition {REVEGETATION METHOD USINF ECO-FRIENDLY REINFORCING MATERIAL}

The present invention relates to an eco-friendly greening composition for ecological restoration and a greening method using the same.

In general, incisions in rivers, coasts, and roads are areas where it is difficult for plants to grow because they are steep slopes, thin or thin areas, or barren areas even with topsoil. In this environment, various vegetation rehabilitation methods are used to artificially create a good growth environment.

Most vegetation afforestation methods use a vegetation base material spraying method in which a large amount of vegetation soil is thickly coated on the slope of the target, and greening compositions such as seeds, fertilizers, adhesives, moisturizers, and cover curing agents are sprayed onto the target area. However, there is a disadvantage that the vegetation of plants decreases over time, since the existing greening method is a method of installing seeds by mixing only seeds in artificial soil, unless continuous management is followed.

Specifically, sowing plant seeds is a common method for greening damaged areas or slopes. If the original ground of the greening target site is soil, only seeds can be sown, but if the soil conditions of the original ground are not satisfactory, a growth base layer is formed for greening and seeds are sown.

Soil, sludge, and compost are mainly used as materials used for greening to create the growth base layer. In recent years, in order to solve environmental problems caused by the use of sewage sludge, etc., there is a trend of using a lot of eco-friendly materials. In addition, in terms of ecology, soil or wood chipping chips generated in the field, and topsoil containing seeds are also mixed and used.

The seeds used are also changing from mainly sheep grasses for early greening to native plants considering the environment. This change in materials and seeds indicates the trend of changing from the recognition that only vegetation is covered to eco-friendly construction considering ecological restoration.

However, the same greening materials are used nationwide because there is still a perception that it is necessary to simply spray and paste good materials on top of the soil characteristics such as strong acidic or alkaline soils.

In addition, since the seeds used are purchased from the outside without any special treatment and are mixed as they are, there are many differences in germination and growth depending on the soil conditions of the slope.

Therefore, an individual treatment method is required according to the soil conditions (soil or soil acidity) of the greening target site showing various characteristics. In addition to the development of eco-friendly greening materials suitable for this, it is necessary to differentiate and use the plants used for greening to meet the soil conditions. There is.

It can be configured.

Hereinafter, specific contents according to the detailed construction method steps of the present invention will be described.

1. Analyze the status information of the target site and select a recording method (Step 1)

In the first step of the present invention, it is possible to perform a process of analyzing the condition information of the target site including the soil condition of the ecological restoration target site and the acidity of the soil, and selecting a greening method.

First of all, the greening process establishes greening methods and targets through the analysis of the target site, and allows the target site improvement and seed pretreatment to be implemented to suit each purpose.

In particular, in this step, the soil characteristics of the target site for greening are investigated and analyzed so that information on the soil quality and soil acidity of the target site can be obtained. The grasp of Saturn and the soil acidity at this stage is the standard for the improvement of the subsequent soil.

Thereafter, depending on the soil (soil condition), the greening method can be decided on whether to perform the neutralization process or the soil improvement, as well as what types of seeds to be introduced.

As will be described later, when the information on the greening target site is identified, the seed pretreatment process to increase the germination efficiency of seeds considering the soil conditions can be performed as an independent process for this. Such seed pretreatment is used by mixing coated seeds and general seeds in a separate process depending on the purpose of greening. Coated seeds are those that wrap seeds with various materials, and have the advantage of maintaining the vitality of seeds and controlling the seed germination timing.

2. The process of improving the soil of the target site for ecological restoration (Step 2)

Since the slope has different soil conditions (various soil quality depending on the soil) and soil acidity (pH), even if the same greening method is applied, the greening quality is different. According to soil conditions and soil acidity, it is necessary to improve the soil to a suitable soil condition for greening before creating a greening layer.

Therefore, in the present invention, after setting a greening target by analyzing information including saturn and soil acidity of the ecological restoration target site (reforestation target site), soil improvement is performed before the greening layer is formed according to the soil characteristics of the ecological restoration target site. do. In upper limb improvement, the soil base is improved in a condition suitable for greening by investigating and analyzing the soil characteristics of the target area. Conditions of the target site are based on Saturn and soil acidity, and improvement according to each condition is carried out before the construction of the greening layer. (As will be described later, the greening layer of the present invention requires construction materials on site when the basic work for construction is completed. It is defined as a laminated structure in which a base layer is constructed by mixing, and a seed layer and a mulching layer are sequentially implemented thereon.)

In the soil improvement of this stage, each control material is mixed with water and sprayed on the target site. In the case of sandy soil (masato) and weathered rock system based on the soil nature of the greening target, mix and spray loess powder so that the clay component can be partially filled between the pores of the coarse soil.

In other words, in the second step, which is this step, state information is classified according to the soil condition and the soil acidity (pH) of the target site for ecological restoration, and when the soil condition of the soil condition is sandy soil and weathered rock system, the loess powder is sprayed as a viscosity modifier. The process is carried out.

In addition, in the case of performing improvement according to the acidity of the soil, when the soil acidity (pH) is acidic, oyster shells and slaked lime powder are sprayed as an acidity control material (A) to neutralize the acidic soil, and the soil acidity ( If pH) is alkaline, spray gypsum phosphate as an acidity control material (B) to neutralize alkaline soil.

In particular, the viscosity control material, the first acidity control material (A) and the second acidity control material (B) may be formed by additionally mixing a dispersion material in water. That is, when the soil improvement work is based on the soil acidity (pH), an acidity control material is used. The first acidity control material (A) is a material for neutralizing acidic soil, and the second acidity control material (B) is used for the purpose of lowering the acidity of alkaline soil. As an example of the first acidity control material (A), oyster shell and slaked lime powder may be applied.

In the case of the above-described first acidity control material (A), the neutralizing agent function of neutralizing the acidic soil and adjusting it to neutrality is performed. That is, where the soil acidity is low, there is a need for a method of reducing the activity of aluminum and reducing the concentration of hydrogen ions. Lime material is generally used as a material that neutralizes such a contaminated area, and it acts to repel hydrogen ions as calcium ions contained in the lime material are dissolved and released. At this time, there is an effect of inactivating aluminum by anions such as phosphoric acid. That is, the material used for neutralization generally uses a lot of lime material. However, because lime material has very low solubility, it is difficult to move with water in the soil. Therefore, it is necessary to take measures to allow the lime material to move with the water.

Existing types of lime materials include calcium carbonate, carbonate goto, lime goto, etc. In the embodiment of the present invention, slaked lime powder and oyster shells may be used when used in a production area. In particular, slaked lime has the advantages of high neutralization efficiency, easy acquisition, easy handling and low price. When quicklime is used, it is effective to use slaked lime because heat is generated when it reacts with water and eventually turns into slaked lime.

In addition, in order to neutralize the original soil with low soil acidity, neutralizing substances must be able to penetrate into the soil. To this end, it is necessary to liquefy the lime material so that particles smaller than the pores of the soil move to the bottom along the pores with water. The treatment of lime material is a surface application, but it is effective to allow lime material to penetrate to a certain depth.

Therefore, in the present invention, for this purpose, a neutralizing agent is provided, and an aqueous solution containing a neutralizing agent (hereinafter, neutralized water) can be applied by mixing it with water.

Specifically, neutralization treatment is required in order to improve the forest restoration target site in a state of low pH based on acidified soil to the target pH 5.5~6.0. In this case, the neutralization treatment is not performed only on the soil surface, but the neutralization agent is used under the soil. A liquid neutralizing agent (neutralized water) is prepared and applied so that it can penetrate to and neutralize the soil.

The neutralizing agent of the present invention may be used by mixing slaked lime powder and oyster shell, respectively, and additionally, a mixed neutralizing agent in which superphosphate is made into powder and mixed in a certain ratio may be prepared.

As an example, the neutralizing agent may be prepared by mixing 50 to 70% of slaked lime, 10 to 40% of oyster shells, and 10 to 20% of superphosphate based on a volume ratio based on the total neutralizing agent. In this case, the dispersant It should be mixed on a 1~2% basis by volume.

In particular, in the case of slaked lime applied to the neutralizing agent of the present invention, in order to improve the properties of the lime substance, it is preferable to make the particles small to accelerate the neutralization reaction. At this time, the lime material can be refined to 0.1~0.5mm through a separate grinding process.

Thereafter, for the production of neutralized water, 20 liters of the above-described mixed neutralizing agent is added to 1 m 3 of clean water, and the neutralized water is obtained by immersing in the mixed water for 1 hour or more.

In this case, the lime material settles on the floor, so a dispersant is added to maintain the suspension. As a dispersant, a lignin compound is used, and the advantage of being able to function as an organic matter when entering the soil with a dispersion effect can be realized. Na-lignosulfonate or Ca-lignosulfonate is used as the dispersant.

Thereafter, the process of spraying the neutralized water on the soil of the restoration target site is performed.

That is, the neutralizing agent is sprayed on the forest restoration target in the form of a liquid mixed with water, but a high volume is formed in the transverse direction on the surface of the ecological restoration target site, and neutralized water obtained by mixing the neutralizing agent with water on the forest restoration target site. After spraying all over, neutralized water is first accumulated in the furrow, and then the step of gradually infiltrating the original ground of the forest restoration target is performed.

Specifically, neutralized water is sprayed on the slope in order to allow the neutralizing agent to penetrate the slope that is the restoration target. At this time, it is desirable to evenly spray the entire area of the target site after digging the furrows (30-50cm intervals) in the transverse direction to facilitate penetration from the slope. This has the advantage of increasing the penetration efficiency by allowing the sprayed neutralized water to first accumulate in the furrow in the transverse direction and then gradually penetrate into the original ground.

In particular, in this case, the water pressure is adjusted so that erosion does not occur on the slope due to spraying of neutralized water, and spraying is applied to allow penetration into the soil. The amount of neutralized water used for this is based on 5ℓ/㎡, and the neutralized water can be sprayed twice or more so that it can evenly penetrate into the soil.

In particular, when the neutralization process is performed by applying neutralized water in consideration of soil acidity, the standard of the neutralizing agent to be sprayed may be calculated and applied in advance.

That is, soil improvement target values are established through diagnosis of soil contamination, and neutralizer application standards are established. The conventional method calculates the treatment amount of the neutralizing agent from the calculated value based on the soil pH, but since the neutralization efficiency varies according to the soil characteristics, it is necessary to clearly calculate the treatment standard of the neutralizing agent.

Accordingly, in the present invention, the step of collecting a soil sample from the target site for ecological restoration, and by adding a neutralizing agent to the collected soil sample in 5% increments in 20 sections, measuring the change in pH for each input section, The neutralizing agent treatment standard is set through the step of calculating the required amount of the neutralizing agent (m) to reach, and the step of calculating the amount of the neutralizing agent applied by the following {Equation 1} using the required amount of the neutralizing agent.

{Equation 1}

Amount of neutralizing agent applied (W) = [Amount of total soil (S)/Amount of soil sample (s)] X Required amount of neutralizing agent (m)

This process has the advantage that it can be applied in a field-specific manner because the factors of the soil's saturn and organic matter content are directly reflected in the experiment.

Furthermore, as the second acidity control material (B), gypsum phosphate may be used. Phosphate gypsum is a by-product from the manufacturing process of phosphate fertilizer and is a material with excellent neutralizing effect of alkaline soil. In particular, it increases calcium content and has high aluminum reduction effect.

These materials are mixed with water and a dispersant is mixed so that the materials are evenly mixed. Ca-lignosulfonate is added as a dispersant so that the ingredients are evenly mixed.

The materials used for soil improvement treatment in this process are mixed with 1㎥ of water in a ratio of 5% based on the volume ratio of water.

It is constructed in the same way without considering the soil condition of the slope, and since the material mixed with seeds is sprayed thickly, there is a lot of loss of seeds. Accordingly, in the present invention, prior to the formation of the growth base layer according to the characteristics of the sloped soil, the soil is improved individually, and the mulching layer is formed on the seed layer, so that optimal conditions for seed germination can be provided. It is possible to provide by improving the construction method.

3. Preparation of growth base materials and seeds for greening (3rd step)

(1) Preparation stage of growth base material

This step is a process of preparing the growth base material to be applied to the target site where the soil improvement process of the target site has been performed and seeds to be put into the greening, and may be prepared in advance in parallel after step 1 as described above.

In the present invention, the greening layer laminated in a multi-layered structure on the surface of the target site is implemented in a structure of a base layer, a seed layer, and a mulching layer, and the growth base material used for the base layer and the seed layer is organic and inorganic materials, soil materials and It can be composed by mixing fibrous materials for strengthening adhesion.

The growth base material includes organic materials including bark, forestry by-products, coffee meals, and charcoal by-products, inorganic materials including zeolite and bermukurete, soil materials including fecal soil and used soil, and medium fiber coco It may be formed by including a fibrous material including net fibers and jute fibers that are short fibers.

In other words, the material used as the growth base material is basically mixed with organic and inorganic materials. As an organic material, bark, wood by-products (root, sawdust, pruning products, lawn mowers, etc.), coffee meal, and charcoal by-products are used, and zeolite and vermiculite are used for inorganic materials.

In addition, fecal soil and sandy loam can be used as soil types. The organic and inorganic materials are mixed so that the organic, inorganic, and soil are mixed in an optimal ratio. The above-described material is a mixture of materials so that the ratio of organic logistics is higher than that of conventional food waste or sludge.In this case, if the original ground condition of the sloped soil is maintained at a certain level, the initial growth is very excellent and the vegetation cover is formed early. It has the characteristics of losing.

In addition, since the mixed material has a lot of organic substances, it has a light weight (specific gravity of 0.9 or less), so it can be attached stably under sloped conditions.

More specifically, the growth base material is bark 5-15%, forest tree by-products 20-40%, coffee meal 1-10%, charcoal by-products 1-15%, fecal soil 10-15%, based on the total volume ratio of the growth base material, It can be used by mixing 10-30% sandy loam, 1-5% zeolite, and 3-5% vermiculite. After the above materials are mixed, 1 to 2% of the useful microbial agent (powder) and 0.5 to 2% of the super absorbent polymer can be further mixed.

In particular, in a preferred embodiment of the present invention, fibers are mixed in order to reinforce the binding force and adhesion of the mixed material. As the fiber, you can use coconut fiber and ?c hemp fiber.

Coconut fiber is mainly used as a product made by twisting with a coernet, etc., but in this invention, fiber in its original state without a net is used. Also, jute fibers are used as short fibers. While these fibers are excellent in tensile strength and durability, they are eco-friendly as materials that naturally decompose after a certain period of time (2 to 3 years).

The fibrous material is mixed with the material at the beginning of the application of the method to increase the binding and tensile strength, and since the fiber material can contain moisture, it naturally plays a role of increasing the moisture-moisturizing power in the growth base layer. In particular, short fibers reinforce the binding strength, and heavy fibers reinforce the tensile strength.

To this end, in particular, the fibrous material applied in the present invention is divided and mixed so that short fibers (jute) and heavy fibers (coconut) can be mixed in a certain ratio. The ratio of short fibers and heavy fibers is mixed at 3:7, and when dividing by length, mix in the ratio of 2±1cm: 5±2cm: 10±1cm = 3:3:4, and the total fiber is the growth base material 1 It is desirable to mix additionally at a rate of 20 kg per ㎥.

Furthermore, when topsoil can be secured in the area of the greening target area for restoration of the original vegetation, topsoil collected by a separate process is mixed within 0-10% by weight based on the total mixture in order to utilize the burial seed resources in the topsoil. Can be used.

As for the materials used for greening, a large amount of sewage sludge is used in consideration of economic efficiency only. If these materials are not sufficiently matured, there is a problem that odor or leachate occurs, and they interfere with plant growth. In addition, there is a problem that the vegetation base layer is hardened, cracks, and falls off by attaching the material to be sprayed by air-tightening or by excessively using an adhesive, but in the present invention, this problem can be eliminated.

In addition, in consideration of the environment, it is preferable to use a high-quality material that does not contain environmentally hazardous substances, and it is necessary to mix a separate eco-friendly material for this, and in the case of the present invention described above, Fibers (fibers) of various lengths are mixed to increase the binding force between materials, and by reinforcing their own tensile force, it is possible to reinforce the adhesion of the material.

(2) Preparation considering growth of seed germination efficiency considering soil conditions

Seed pretreatment is used by mixing coated seeds and general seeds in a separate process according to the purpose of greening. Coated seeds are those that wrap seeds with various materials, and have the advantage of maintaining the vitality of seeds and controlling the seed germination timing.

Except for coated seeds, immersion treatment is carried out in which seeds mixed for vegetation restoration targets are put in clean water for at least 6 hours at the site. Seeds purchased from outside have a difference in germination rate depending on the collection time and storage method (period, temperature, humidity, etc.). Therefore, in order to increase the greening effect, it is necessary to improve the germination rate above a certain level through seed treatment.

For seed immersion treatment, mix giverelin and a separate seed skin treatment mixture in water at a volume ratio of 5%, and make sure that the seeds are sufficiently immersed in the solution.

Seeds are applied by dividing the ratio of use of general seeds and coated seeds according to the characteristics of each soil. After construction, general seeds germinate first to improve the poor soil environment, and after a certain period of time, it is necessary to adjust so that the coated seeds germinate and plants for greening can be surely settled.

If the acidity of the target soil is acidic or alkaline is strong, increase the mixing ratio of the coated seeds. According to the goals of early and long-term greening, the mixing ratio of seeds is applied differently.

Thus, preparing the seeds of this step 3 is to form seeds to be included in the seed layer using the pretreated seeds, but the seeds mixed in the seed layer are uncoated plants that can germinate early and cover the target site. The seed and the coated plant seed whose germination period is delayed in consideration of the neutralization state over time of the target site are mixed and applied.

4. Implementation of greening layer (base layer + seed layer + mulching) (4th stage)

Thereafter, in the present invention, a base layer is formed by spraying a growth base material on the surface of the target site, and a seed layer in which the growth base material and seeds are mixed is constructed on the base layer. In particular, the construction material is mixed at the site. Then, the base layer is constructed, and the seed layer and the mulching layer are sequentially constructed on it. The mounting of the mixed material is divided into three layers and applied.

2 is a schematic cross-sectional view illustrating such a greening layer.

As shown, it is implemented in a structure in which the greening layer 20 is stacked on the sloped base plate 10 that is the target site.

In this case, the greening layer 20 is formed such that the base layer 22 is constructed, and the seed layer 24 and the mulching layer 26 are sequentially stacked thereon.

In this case, the base layer 22 is attached to the base layer 22 without mixing seeds (S) about 0.5 to 1.0 cm, and the seed layer mixed with seeds thereon is also attached to a thickness of about 0.1 to 1 cm.

After the seed layer 24 is attached, a mulching layer in which only wood fiber is mixed is attached to the surface to a thickness of about 0.5 cm. Therefore, the seed layer 24 is positioned between the base layer 22 and the mulching layer 26 to provide optimal conditions for seed germination.

In slope conditions, nets are additionally installed according to the characteristics of the construction target site. In this invention, since a lot of fibers of various lengths are mixed in the mixed material, a separate net is not required. However, in order to increase the adhesion of the material in places where dry damage or leachate is concerned due to field conditions, or in places with a steep slope Can be installed.

In particular, the formation of the seed layer in the fourth step of the present invention is, in the case of early greening, the mixing ratio of coated seeds and uncoated seeds is, when the pH is less than 5.5, coated seeds: uncoated seeds = 5:5, pH 5.5 In ~7.5, the mixing ratio of coated seed: uncoated seed = 0:10, and in the case of pH exceeding 7.5, coated seed: uncoated seed = 3:7 is applied.

Further, in the case of long-term greening, the mixing ratio of coated seeds and uncoated seeds is, when the pH is less than 5.5, coated seeds: uncoated seeds = 6:4, in pH 5.5 to 7.5, coated seeds: uncoated seeds = 2:8, In the case of pH exceeding 7.5, a mixing ratio of coated seed: uncoated seed = 4:6 is applied.

In this case, it is preferable to apply the seed to the plant species that can be germinated early and covered with the plant species that can germinate and grow with a time difference. That is, if the soil acidity is acidic, the soil acidity will have the characteristics of acidic soil during an initial period of time until a rapid neutralization reaction occurs after application of the first acidity control agent. Seeds that use strong plant seeds (seeds in an uncoated state), and seeds that allow germination after soil neutralization have been achieved, do not germinate in the initial acidic environment by coating the surface, and then in the neutralized state. It is desirable to allow germination to occur.

Accordingly, as uncoated seeds capable of initial germination, it is preferable to use pine, evening primrose, silver grass, etc., which can grow even in acidified soil.

Subsequently, the seeds (coated seeds) to be used in the coated state can be used as general plant seeds, and if necessary, it is also possible to use by controlling the germination time by coating any one of the above-described pine, evening primrose, and silver grass.

The coated seeds are talc. Coating is performed with a mixture of ocher, powdered microbial agent, and adhesive. Such coated seeds have the power to withstand drying, and when the seeds germinate and root, they are in direct contact with the microbial agent, thereby promoting local establishment and growth.

In particular, since coated seeds are delayed by 2 to 4 weeks at the start of germination, normal seeds (uncoated seeds) can be germinated sequentially after germination and settling in a state where the soil layer is stabilized to some extent.

To this end, the coating allows a coating layer of about 1 to 2 mm to be formed on the outside of the seed. When it exceeds the range of the upper coating layer, the germination rate is extremely low, and when the thickness of the coating layer is less than 1 mm, the coating power is weakened, and the growth is inhibited by germinating earlier than the desired germination stage due to moisture penetration.

Coated seeds are stored in a constant temperature and humidity room below 4℃, and after being stored at room temperature 2-3 days before construction, put them on site. In the field, coated seeds and general seeds are mixed and used according to the goal of vegetation restoration.

Thereafter, a step of implementing a mulching layer may be added as a 5 step process. In this case, the mulching layer may be composed of a layer composed of wood fibers on the seed layer.

Since the mulching layer is evenly covered with the material in the seed layer located at the bottom, moisture can be maintained for a long time so that the vitality of the seeds in the bottom does not decrease. Also, by creating a mulching layer, the slope that has been completed is relatively The advantage of showing a uniform texture is realized.

Hereinafter, an experimental example of an individual configuration for the construction process according to the present invention will be described.

3 and 4 are images and graphs showing examples of pretreatment of seeds.

-Experimental Example 1 (seed pretreatment experiment)

A seed pretreatment experiment was conducted on redwood among the wood species used for greening.

In the experiment, seeds were immersed in water mixed with gibberellin and seed skin treatment material for more than 6 hours, and then 100 grains were placed in Petri dish, and then put in a thermostat (25°C) and the germination rate was measured.

As a result of measuring the germination rate, it was analyzed that the treatment method was effective compared to that without seed pretreatment (it can be seen that the germination rate of seeds was rapidly improved on the 7th day of the germination experiment).

In addition, the overall germination rate was 40% without pretreatment, but it was found that the germination rate could be improved to 90% level through pretreatment.

Accordingly, it can be seen that all of the seeds forming the seed layer in the construction process applied to the present invention are pretreated to greatly enhance the germination rate.

-Experimental Example 2 (Construction experiment of mulching layer)

5 is an image showing an experiment result of forming a mulching layer.

(a) is an image after forming only the base layer and seed layer, and (b) is an image showing the result after adding a mulching layer on the base layer and seed layer.

For the method of forming the growth base layer, an on-site mounting experiment was conducted under the condition of improving the mounting method with a multi-layered structure. The mounting experiment was conducted on the artificial slope behind the Cheongju factory.

The applied method was compared with the method of forming the base layer and the seed layer in the usual manner and the method of forming a mulching layer made of wood fiber on the seed layer.

In the test construction, seeds were not mixed in the seed layer in order to understand only the physical properties of the material. As for the construction thickness, a base layer of 3 cm, a seed layer of 1 cm, and a mulching layer of 0.5 cm were formed.

(a) It can be seen that the wood chips mixed with the material are exposed as it is in the state where only the seed layer is applied and the mulching layer is not formed thereon. In this case, there is a concern that the entire growth base layer may be dried as the rough particles on the surface are exposed to air.

(b) On the other hand, when the mulching layer is additionally formed, it is judged that moisture can be maintained for a long time so that the vitality of the seeds underneath does not decrease because the material in the seed layer located below is evenly covered. In addition, by forming a mulching layer, it has the advantage that the slopes on which the construction is completed can exhibit a relatively uniform texture.

-Experimental Example 3 (Method of soil improvement)

6 is a photograph showing a process of measuring the change of pH according to the soil improvement treatment, FIG. 7 is a measurement result of the first acidity control material (A), and FIG. 8 is the measurement result of the second acidity control material (B) It is a graph showing.

An experiment was conducted to find out the change in soil characteristics when the original soil was treated with a soil modifier. In this experiment, soil modifiers were mixed with water and sprayed to permeate the soil to improve soil quality.

When the soil conditioner was sprayed on the outside soil, it was measured that the soil conditioner penetrated to about 10~15cm below the original ground, and it is considered that there is a soil improvement effect on the soil conditioner up to this part.

For more accurate measurement, the soil of the experimental zone was collected and an experiment was conducted to control soil acidity by depth indoors, and the measurement results are as follows.

For the soil acidity of the official soil, soil pH 4.9 was used for acidic soil (collected from Bonghwa-gun), and soil pH 8.0 was used for alkaline soil (collected from Okgye-myeon).

As shown in Figure 7, as a result of treating the first acidity control material for acidic soil, in the case of the treatment agent having a concentration of 5%, there was a change in soil acidity only up to about 2 cm of the surface layer, but the concentration of the acidity control material was raised to a level of 10-20%. In this case, it was possible to measure the change in soil acidity up to about 10 cm deep.

In addition, referring to Figure 8, in the case of the Cali-seong soil was experimented for each of four concentrations. In the case of the second acidity control material (B) treatment, there was a change in the soil acidity in the surface layer, but there is a slight difference compared to the first acidity control material (A) depending on the soil depth.

Although the range of change was small up to the concentration of the acidity control material of 5-10%, when the concentration of the sample was more than 20%, there was an effect on the treatment of the control agent up to a depth of 10 cm.

Therefore, if the acidity control material (A, B) is treated before the growth base layer is formed, it is judged that there is an effect of improving the soil acidity condition to a certain level.

In the detailed description of the present invention as described above, specific embodiments have been described. However, various modifications are possible without departing from the scope of the present invention. The technical idea of the present invention is limited to the above-described embodiment of the present invention and should not be defined, and should not be determined by the claims as well as the claims and equivalents.
