Description

Composition for improving soil environment including red roof moss, and method for improving soil environment using the same

[0001] The present invention relates to a composition for improving a soil environment comprising Ceratoma purpureus (Ceratodon purpureus) or microorganisms derived therefrom, and a method for improving a soil environment using the same, and more specifically, to a composition that can create an environment for plant growth by increasing organic matter, nitrogen content, and cation exchange capacity of the soil when applied to the soil.

[0002] As bryophytes, mosses were the first plants to adapt to life on land, and possess exceptional environmental adaptability and survival capabilities. This resilience allows mosses to be found in every region of the globe, from tropical rainforests to tundra, excluding deserts and oceans. They are also among the first species to emerge in areas devastated by natural disasters like forest fires and droughts.

[0003] Meanwhile, extensive research and various methods are being developed to improve degraded or polluted soils. Among them, "phytoremediation," which can secure both environmental friendliness and economic feasibility, is gaining attention. Compared to conventional soil improvement methods, soil purification through plant cultivation can be significantly cost-effective and environmentally friendly. However, phytoremediation can only be applied to soils that support plant growth. In soils where plant growth is difficult, it is difficult to expect soil improvement effects through plant growth.

[0004] Therefore, it is expected that the soil environment can be improved economically and environmentally by utilizing moss, which can easily take root in soils where general plants have difficulty taking root.

[0005] Accordingly, the inventors of the present invention have confirmed that the soil-attaching ability of the red roof moss is excellent, and that when the red roof moss is applied to the soil and cultured, it is possible to improve the soil environment by increasing the organic matter, nitrogen content, and cation exchange capacity in the soil.

[0006] Accordingly, the purpose of the present invention is to provide a composition for improving soil environment containing red roof moss (Ceratodon purpureus).

[0007] Another object of the present invention is to provide a method for improving the soil environment using a composition for improving the soil environment containing red roof moss.

[0008] The present invention relates to a composition for improving a soil environment including a red roof moss, and a method for improving a soil environment using the same. The composition of the present invention enables improvement of the soil environment by increasing the organic matter or nitrogen content and cation exchange capacity in the soil.

[0009] Hereinafter, the present invention will be described in more detail.

[0010] One aspect of the present invention relates to a composition for improving soil environment, comprising Ceratonia purpureus, a pulverized product thereof, or a culture thereof.

[0011] The term "roof moss" in this specification refers to a plant species belonging to the genus Ceratodontidae of the family Ditrichaceae among bryophytes, which is widely distributed throughout the world from polar regions to tropical regions as well as Japan, China, France, and America, and forms colonies on rooftops of buildings in sunny urban areas or rural areas, or on dry soil.

[0012] The term "crushed material" in this specification means a state in which an object is broken into pieces or particles due to an external force applied to the object, and the crushed material may have an average particle size of 0.01 to 50 mm, and more specifically, may have an average particle size of 0.5 to 10 mm, but is not limited thereto.

[0013] When producing a powdered product of red roof moss according to the present invention, not only red roof moss that has not undergone a separate treatment process, but also frozen red roof moss, dried red roof moss, freeze-dried red roof moss, or red roof moss that has undergone other preservation treatments can be utilized.

[0014] The term "culture" in this specification means a material obtained by growing or propagating a subject for a predetermined period of time in an environment appropriate to the growth environment of the subject, and obtaining part or all of the subject upon completion of growth. The culture may further contain other organisms or biological or chemical impurities other than the subject to be grown.

[0015] The term "soil environment" in this specification refers to all physical, chemical or biological properties of the soil, and more specifically, may refer to, but is not limited to, soil organic matter content, total nitrogen content in the soil, ion content in the soil, phosphate content in the soil, characteristics of soil microbial communities, content of plant-useful microorganisms in the soil, cation exchange capacity of the soil and soil pH, etc. that affect soil-based plant growth.

[0016] The term "improving the soil environment" in this specification means changing the soil environment so as to ensure the stability, diversity, and sustainability of the soil-based ecosystem, and more specifically, it can mean ensuring the stability and diversity of the soil ecosystem by changing the soil environment so as to be more suitable for the growth of plant groups that play a producer role in the soil ecosystem. The composition including the roof red moss according to the present invention can increase the organic matter content, nitrogen content, available phosphorus content, and cation exchange capacity in the soil, and can adjust the soil pH to a slightly acidic state that is favorable for plant growth, and thus it is thought that it can be utilized as a preparation for improving the plant growth environment for polluted or depleted soil (Figs. 3 to 7).

[0017] The composition according to the present invention may further include additives generally used for soil management, for example, organic additives such as organic acids, peat, or crushed and fermented products of organisms, inorganic additives including minerals such as sand, clay, and zeolite, soil microbial agents, soil activators, or molding agents such as thickeners for molding soil particles, but are not limited thereto.

[0018] Another aspect of the present invention relates to a method for improving a soil environment, comprising the following steps: a treatment step of treating soil with a composition for improving a soil environment, the composition comprising at least one selected from the group consisting of roof moss, crushed roof moss, and cultured roof moss.

[0019] In one embodiment of the present invention, the method may further include a soil culturing step of cultivating soil treated with a composition for improving soil environment for a predetermined period of time.

[0020] When cultivating soil treated with a composition for improving soil environment, a synergistic improvement effect on growth conditions can be obtained through the interaction between moss sprayed on the soil and microorganisms native to the soil.

[0021] The present invention relates to a composition for improving a soil environment including a red roof moss, and a method for improving a soil environment using the same. When the composition according to the present invention is applied to soil, organic matter or total nitrogen, available phosphorus, and cation exchange capacity in the soil increase, and the soil pH is adjusted to be slightly acidic, so that the soil environment of devastated or contaminated soil can be improved through the composition of the present invention.

[0036] Example 1. Evaluation of the survival ability of red roof moss

[0037] Roof red moss was legally harvested from a field in Bukpyeong-myeon, Jeongseon-gun, Gangwon-do, and soil from reclaimed land along the coast of Taean-gun, Chungcheongnam-do was legally collected. The process for harvesting roof red moss is illustrated in Figure 1.

[0038] Afterwards, 10 g of the obtained roof red moss was washed with a 2% (w / v) citric acid solution, 100 mL of a 10% (w / v) NaCl solution was added, and the moss was ground through a grinder to prepare a ground moss solution.

[0039] Reclaimed soil with a pulverized moss solution evenly applied to the surface was set as the experimental group for evaluating the survival ability, and reclaimed soil with 100 mL of a 10% NaCl solution without moss was set as the control group.

[0040] The experimental and control soils were treated with each solution twice a week for four weeks, for a total of eight treatments. After the solution treatment, the soil's ability to establish was assessed by visual observation. The results are shown in Figure 2.

[0041] As a result of the observation, it was confirmed that the soil of the experimental group was generally colonized by the establishment of a colony of red roof moss, whereas no plant group was established in the soil of the control group, confirming that the soil establishment ability of red roof moss was excellent.

[0042]

[0043] Example 2. Evaluation of the soil environment improvement ability of red roof moss.

[0044] The soil environment improvement ability of the roof red moss obtained according to Example 1 was evaluated.

[0045] Specifically, experimental and control groups were set for the reclaimed land soil according to the same criteria as Example 1, and the soil treated with a solution containing and not containing the crushed red roof moss was transferred to an incubator and cultured. The culture temperature was 20℃, and the light irradiation condition was 14 hours of light on followed by 10 hours of light off. The solution was treated twice a week for 30 days, a total of 8 times, and culture was performed according to the above conditions for each solution treatment.

[0046] After completion of cultivation, 300 g of soil was randomly extracted from the experimental and control groups, and soil composition analysis was conducted on soil organic matter content, soil pH, total nitrogen content, available phosphorus content, and soil cation exchange capacity (AT Analysis Center), and the results of each analysis are shown in Figures 3 to 7 and Tables 1 to 5.

[0047] Control group, experimental group, organic matter content (%) 0.642.55

[0048]

[0049] Control group, experimental group, soil pH 6.836.3

[0050]

[0051] Control group experimental group total nitrogen N (%) 0.0280.071

[0052]

[0053] Control group, experimental group, available phosphate (P2O5, mg / kg) 8.2911.04

[0054]

[0055] Control group Experimental group Cation exchange capacity (cmol + / kg)2.104.80

[0056]

[0057] As a result of the analysis, the soil treated with red roof moss had about 4 times more organic matter (%), about 2.5 times more total nitrogen (N), about 1.3 times more available phosphorus, and about 1.3 times more cation exchange capacity (cmol) than the control group. + / kg) increased by about 2 times, and the soil pH was adjusted to about 6.3, forming slightly acidic soil conditions more favorable for plant growth.

[0058] From these results, it was confirmed that by treating the reclaimed land soil with incomplete plant growth with red moss, the soil environment can be improved to be more suitable for plant growth.

[0059] The purpose of the present invention is to provide a composition for improving soil environment containing red roof moss (Ceratodon purpureus).
