Embodiments for Carrying Out the Invention

[0012] Hereinafter, a method for producing a mineral material derived from seaweed fossils, a method for producing mineral water derived from seaweed fossils, and a cultivation method for crops and the like using them according to an embodiment of the present invention will be described with reference to the drawings.

[0013] (Seaweed fossils) First, in this specification, "seaweed fossils" also referred to as algal fossils or fossil substances derived from algae, refer to natural fossil substances in which seaweeds have been deposited or mineralized over geological time, and include those containing a siliceous component or a calcareous component as the main component. The seaweed fossils include, but are not limited to, those derived from fossils of seaweeds such as diatoms and calcareous algae.

[0014] One of the purposes of the present invention is to efficiently supply mineral components to grains and crops. It is characterized in that it utilizes natural natural materials, seaweed fossils, as raw materials instead of general chemically synthesized mineral materials or artificially prepared mineral resources.

[0015] The seaweed fossils used in this embodiment are, for example, porous fossil substances formed by seaweeds, plankton, etc. being deposited under the influence of geological actions such as crustal movements in an ancient marine environment and undergoing a long period of time, and are obtained by mining those existing in a deposited state underground.

[0016] Figure 1 shows a schematic diagram of seaweed fossils deposited underground and the state of excavated seaweed fossils. Figure 1(a) shows the deposition situation of seaweed fossils underground. The seaweed fossil 10 exists underground as a soft and porous marine sediment formed by the deposition and mineralization of seaweeds, plankton, etc. Figure 1(b) shows the excavated seaweed fossil 10, and Figure 1(c) shows the pulverized seaweed fossil 11 obtained by pulverizing the seaweed fossil 10.

[0017] (Mineral Components and the Significance of Their Supply) Minerals are important nutrients for the human body, but since they cannot be synthesized in the body, it is necessary to ingest them through daily diet, etc. For example, calcium (Ca) and magnesium (Mg) contribute to maintaining the health of bones and muscles, and iron (Fe) and zinc (Zn) are known to be involved in body growth and metabolism. Also, since mineral components affect each other, it is important to ingest multiple minerals in a balanced manner rather than a single component.

[0018] Examples of foods containing minerals include seaweeds rich in iodine (I), nuts and seeds containing magnesium (Mg) and zinc (Zn), dairy products containing calcium (Ca), etc. In Japan, based on the dietary intake standards under the Health Promotion Law, multiple mineral elements such as zinc (Zn), potassium (K), chromium (Cr), selenium (Se), iron (Fe), copper (Cu), sodium (Na), magnesium (Mg), manganese (Mn), molybdenum (Mo), iodine (I), phosphorus (P), etc. are specified.

[0019] However, it is not always easy to ingest these mineral components daily and stably. Although it is desirable to be able to ingest them through grains or crops such as water, rice, fruit trees, vegetables, etc., not all grains and crops contain sufficient amounts of mineral components.

[0020] Therefore, the seaweed fossil-derived mineral material and water containing seaweed fossil-derived mineral components according to this embodiment are manufactured using the aforementioned seaweed fossil as a raw material and by the manufacturing method shown in the examples described later. That is, by processing the seaweed fossil in a predetermined process, a mineral material having a porous structure and containing multiple types of mineral components, and water containing mineral components eluted from the seaweed fossil can be obtained. These are used to supply mineral components to grains or crops through application to soil or spraying onto plants.

[0021] (Example 1: An example of a method for producing mineral material derived from seaweed fossils) Next, an example of a method for producing the seaweed fossil-derived mineral material according to this embodiment will be described with reference to Figures 2 and 3. Figure 2 shows a schematic diagram of an example of a method for producing the seaweed fossil-derived mineral material according to this embodiment. Figure 3 shows a flowchart of an example of a method for producing the seaweed fossil-derived mineral material according to this embodiment.

[0022] As shown in Figure 3, the method for producing the seaweed fossil-derived mineral material according to this embodiment is as follows: The crushing process (S100) involves crushing the excavated seaweed fossils, A firing process (S110) in which the crushed seaweed fossil is heated and fired at a temperature of 800°C to 1000°C while adding water, A cooling step (S120) is performed to cool the calcined material obtained in the calcination step to obtain a mineral material derived from seaweed fossils with a particle size in the range of 0.1 mm to 6 mm and a moisture content in the range of 15% to 30% by mass, It has.

[0023] Each step will be explained in detail.

[0024] In the crushing process (S100), the excavated seaweed fossils 10 are destroyed and crushed using machinery such as crushers and pulverizers to obtain finely granular or powdered crushed seaweed fossils 11.

[0025] At this stage, the crushed seaweed fossil 11 is further crushed as needed to enable uniform heating and stirring in the calcination process (S110) described later. For example, it is preferable to crush it again before putting it into the heating container (kettle) 20, and if large lumps are found after putting it in, crush it again to make it into a powder.

[0026] In the firing process (S110), the crushed seaweed fossil 11, more specifically the powdered seaweed fossil 12, obtained in the crushing process (S100), is placed into a heating container (kettle) 20 equipped with a thermometer 22.

[0027] Next, as shown in Figure 2(a), mist-like water 30 is supplied from above to the powdered seaweed fossil 12, and the water is distributed throughout the powdered seaweed fossil 12 while stirring with the stirring device 24. After confirming that the water has been distributed throughout, the heater 23 is started.

[0028] Subsequently, as shown in Figure 2(b), the supply of water 30 is stopped, and the powdered seaweed fossil 12 is heated and calcined while being stirred in a temperature range of 800°C to 1000°C. This heating and calcination is adjusted according to the season and ambient humidity, but by continuing to stir at a high temperature, the water and powdered seaweed fossil 12 are kneaded together, and boiling, stirring, and calcination proceed simultaneously in a mixed state.

[0029] If this state is maintained for a certain period of time, the powdered seaweed fossil 12 gradually becomes granular and then changes into a granular state. For example, by heating, stirring, and calcining for a period of 3 to 5 hours while monitoring the moisture content until it reaches a predetermined range (for example, a moisture content within the range of 15% to 30% by mass), a calcined product with a particle size in the range of 0.1 mm to 6 mm can be obtained.

[0030] Once the predetermined particle size and moisture content are confirmed, the heater 23 is stopped.

[0031] In the cooling process (S120), as shown in Figure 2(c), the fired product obtained in the firing process (S110) is allowed to cool naturally in the heating container 20. That is, the heating container 20, the inside of the container, and the granular or granular fired product are cooled without further heating until they reach room temperature.

[0032] After cooling to room temperature, the granular or granular calcined material with a particle size between 0.1 mm and 6 mm is transferred to a separate container as shown in Figure 2(d) and recovered as seaweed fossil-derived mineral material 15.

[0033] The obtained seaweed fossil-derived mineral material 15 has a porous structure and is breathable, so it is filled in predetermined amounts into, for example, packaging bags 50 with fine pores formed on the surface. The amount to be filled is not particularly limited, but as an example, it can be filled into a breathable bag as shown in Figure 2(e) and amount to about 15 kg.

[0034] The seaweed fossil-derived mineral material 15 obtained in this manner is used as a soil conditioner 16 and is scattered or mixed into the soil in the cultivation method described later.

[0035] (Example 2: Other examples of methods for producing mineral materials derived from seaweed fossils and methods for producing mineral water derived from seaweed fossils) Next, another example of a method for producing seaweed fossil-derived mineral material and a schematic diagram of an example of a method for producing seaweed fossil-derived mineral water according to this embodiment will be described with reference to Figures 4 and 5. Figure 4 shows a schematic diagram of an example of a method for producing seaweed fossil-derived mineral material and seaweed fossil-derived mineral water according to this embodiment. Figure 5 shows a flow chart of an example of a method for producing seaweed fossil-derived mineral material and seaweed fossil-derived mineral water according to this embodiment.

[0036] As shown in Figure 5, the method for producing the seaweed fossil-derived mineral material according to this embodiment is as follows: The crushing process (S200) involves crushing the excavated seaweed fossils, The crushed seaweed fossil is boiled at a temperature of 700°C to 800°C while adding water (S210), A cooling step (S220) is performed to cool the product obtained in the boiling step, A liquid separation step (S230) is performed to separate the liquid component from the product obtained after the cooling step and obtain the remaining solid mineral material derived from seaweed fossils, It has.

[0037] Furthermore, the seaweed fossil-derived mineral water according to this embodiment is the liquid component obtained in the liquid separation step (S230) described above, and the method for producing the seaweed fossil-derived mineral water is as follows: The crushing process (S200) involves crushing the excavated seaweed fossils, A boiling process (S210) is performed in which the crushed seaweed fossils and water are boiled at a temperature of 700°C to 800°C while adding water in a weight ratio range of 1:4 to 6, A cooling step (S220) is performed to cool the product obtained in the boiling step, A solid separation step (S240) is performed to separate the solid components from the product obtained after the cooling step and obtain the remaining liquid mineral water derived from seaweed fossils, It has.

[0038] Each step will be explained in detail.

[0039] In the crushing process (S200), the excavated seaweed fossils are destroyed and crushed using crushers, pulverizers, etc., to obtain powdered or finely granulated crushed seaweed fossils. This crushing process increases the contact area between the seaweed fossils and water in the boiling process (S210) described later, promoting the leaching of mineral components.

[0040] In the boiling process (S210), the crushed seaweed fossils obtained in the crushing process (S200), more specifically the powdered seaweed fossils 12, are placed into the heating container (kettle) 20.

[0041] Next, as shown in Figure 4(a), a predetermined amount of water is added, and the water is distributed throughout the powdered seaweed fossil 12 while stirring with the stirring device 24. After that, the lid 21 is attached, and the heater 23 is activated to start boiling while monitoring the temperature with the thermometer 22.

[0042] The powdered seaweed fossil 12 and water 30 are heated in a temperature range of 700°C to 800°C, and boiled with stirring. Boiling at a temperature of around 750°C is particularly preferable. The boiling time is adjusted according to ambient temperature and seasonal conditions, but for example, heating and boiling are performed for a range of 10 to 15 hours, more preferably around 12 hours, and the boiling is terminated by stopping the heater 23 as shown in Figure 4(b).

[0043] After the boiling process (S210) is completed, in the cooling process (S220), the lid 21 is opened as shown in Figure 4(c). Then, the contents are allowed to cool naturally for 10 to 15 hours while being slowly stirred manually using a stirring tool or the like (a blower or the like may also be used) until they reach room temperature.

[0044] In the liquid separation step (S230), as shown in Figure 4(d), the liquid component is separated from the product obtained after the cooling step (S220), and the remaining solid component, a residue 18 containing rare metals and mineral components derived from seaweed fossils, is recovered. This separation can be carried out, for example, using a separation apparatus equipped with a filter 36 and a water receiver 37 provided on a base 35. The residue 18 obtained in this step can be used as a seaweed fossil-derived mineral material containing high concentrations of mineral components derived from seaweed fossils, and can be used as a soil conditioner, etc. In this specification, "rare metals" refers to metallic elements that are relatively scarce in the Earth's crust or have high industrial value, and in the present invention, this includes, but is not limited to, vanadium, molybdenum, strontium, zirconium, nickel, cobalt, etc.

[0045] On the other hand, the solid separation step (S240) is a step in which solid components are separated from the product obtained after the cooling step (S220) and the remaining liquid components are recovered. The liquid components obtained in this step are water containing mineral components derived from seaweed fossils (seaweed fossil-derived mineral water) 44, which contains mineral components dissolved from seaweed fossils. This seaweed fossil-derived mineral water 44 is extracted as an extract-like liquid using a filter 36 or the like.

[0046] Since the components of the obtained seaweed fossil-derived mineral water 44 may be affected by light and temperature, it is preferable to fill it into a hard plastic bottle 45, for example, and store it in a tightly sealed container.

[0047] (Example 3: Cultivation method for crops etc. using mineral material derived from seaweed fossils or mineral water derived from seaweed fossils) Next, an example of a method for cultivating crops using the seaweed fossil-derived mineral material and seaweed fossil-derived mineral water according to this embodiment will be described.

[0048] In this embodiment, granular seaweed fossil-derived mineral material is scattered or mixed into the soil as a soil conditioner, allowing plants to absorb natural mineral components through their roots. Additionally, seaweed fossil-derived mineral water is sprayed onto leaves, bark, fruits, etc., allowing plants to absorb natural mineral components from their bodies as well.

[0049] Figure 6 shows a schematic diagram of the process of scattering and mixing the soil conditioner containing the seaweed fossil-derived mineral material according to this embodiment onto soil. Figure 6(a) shows an example in which the soil conditioner 16 is scattered on the surface of soil 14, and Figure 6(b) shows an example in which the soil 14 and the soil conditioner 16 are mixed together.

[0050] When used in a field, granular seaweed fossil-derived mineral material 16 should be spread over the entire soil 14 or between the rows before sowing or transplanting. It can also be mixed with compost or other fertilizers as needed.

[0051] When using the seaweed fossil-derived mineral material according to this embodiment in the growing medium for seedling cultivation, it is preferable to mix it in a ratio of 5% to 10% by mass relative to the total amount of the growing medium.

[0052] Figure 7 shows a schematic diagram of the application of the seaweed fossil-derived mineral material according to this embodiment to the base of fruit trees or to the surrounding soil. Figure 7(a) shows an example in which the soil conditioner 16 is applied around the base of fruit trees such as apples or mixed with soil 14. Figure 7(b) shows an example of similar application to fruit trees such as grapes. Figure 7(c) shows an example in which the soil conditioner 16 is applied to vegetables or mixed with soil. Figure 7(d) shows an example in which the soil conditioner 16 is applied between the rows of crops such as strawberries and mixed with soil 14 as needed.

[0053] After being applied to or mixed into the soil, rainfall and watering allow the natural mineral components contained in the seaweed fossil-derived mineral material to penetrate the soil and be absorbed by the roots of crops.

[0054] While tap water can be used for watering, well water is preferable as it provides water closer to natural conditions. River water or similar water can be pumped up using a submersible pump and used to water the soil surface or the base of trees with a sprinkler 60 or similar device. In addition, in greenhouse cultivation, irrigation can be carried out using tap water or well water.

[0055] Assuming that one bag of granular seaweed fossil-derived mineral material, packaged in a bag, weighs 15 kg, the estimated application rate per 10 ares is: Rice: 3 bags to 5 bags Vegetables: 5 bags to 7 bags Fruit trees: 5 bags or more and 7 bags or less Flowers: 3 bags or more, 4 bags or less It is preferable to use an amount of this quantity. The application rate can be adjusted as appropriate, up to approximately 12 bags, depending on climatic conditions, soil conditions, crop type, etc.

[0056] Figure 8 shows a schematic diagram of how the seaweed fossil-derived mineral water according to this embodiment is sprayed onto tree bark, fruit trees, leaves, etc. Figure 8(a) shows an example of spraying the bark B, fruit F, and leaves L of an apple fruit tree using a sprayer 65. Figure 8(b) shows an example of misting the bark B, fruit F, and leaves L of a grape fruit tree. Figure 8(c) shows an example of spraying the leaves L of flowers and vegetables. Note that spraying the bark B, fruit F, and leaves L of an apple fruit tree may also be done using a spray vehicle such as the speed sprayer 66 shown in Figure 8(d).

[0057] When absorbing natural mineral components from plants, use water containing mineral components derived from seaweed fossils. Specifically, add the seaweed fossil-derived mineral water 15 to the tank of a sprayer, dilute it with water to about 10 times its original volume, and then spray it onto the target object in a shower or mist form.

[0058] Furthermore, in the case of fruit trees (such as grapes and apples), covering the fruit with a paper bag or similar after spraying can suppress the evaporation of mineral components and improve absorption.

[0059] According to the cultivation method using the seaweed fossil-derived mineral material and seaweed fossil-derived mineral water of this embodiment, improvements in crop root development, growth, reduction of diseases and pests, and improvement of continuous cropping problems were confirmed. Furthermore, improvements in quality, shape, taste, sugar content, and shelf life were observed in the harvested crops.

[0060] Specifically, for example, in the case of rice, the yield, which was normally around 7-8 bales per tan (approximately 0.1 hectare), was observed to increase to about 10 bales. In addition, recovery of tree vigor was observed in fruit trees, growth of root vegetables was promoted, and improvements in size and sweetness were observed in fruits.

[0061] Furthermore, improvements in the soil environment promoted the growth of mycorrhizal fungi and other organisms that have symbiotic relationships with plants, suggesting an improvement in nutrient absorption efficiency.

[0062] (Example of ingredients) As an example, Table 1 shows the natural overall elemental components analyzed by fertilizer testing for conventional soil conditioners.

[0063] [Table 1] The conventional soil conditioners shown in Table 1 contain silicon (Si) as the main component, along with inorganic elements such as calcium (Ca), magnesium (Mg), manganese (Mn), iron (Fe), sulfur (S), boron (B), chlorine (Cl), fluorine (F), and molybdenum (Mo). Furthermore, they have been confirmed to contain trace elements and rare metal components such as zinc (Zn), copper (Cu), vanadium (V), nickel (Ni), cobalt (Co), and selenium (Se).

[0064] These conventional soil conditioners are characterized by containing a variety of mineral components, compared to general chemical fertilizers and single-component mineral fertilizers, and have been used to improve the chemical properties of soil and supply trace elements to crops. Some also contain organic matter, which is believed to have a certain effect on improving soil water retention and physical properties.

[0065] Next, Table 2 shows the results of component analysis performed on the seaweed fossil-derived mineral material obtained by the manufacturing method according to Example 1.

[0066] [Table 2] The component analysis results shown in Table 2 were measured by X-ray fluorescence analysis, and the elemental content is shown as the value of each element converted to its oxide form. Furthermore, this analysis included elements detected at 0.01% by mass or higher.

[0067] As shown in Table 2, the seaweed fossil-derived mineral material according to this embodiment contains silicon (Si) as its main component, accounting for a high proportion in terms of silicon dioxide (SiO2). Silicon is known to be a component that contributes to the formation and strengthening of plant cell walls, suggesting that the mineral material according to the present invention is useful as a soil conditioner.

[0068] Furthermore, the mineral material in this embodiment contains major inorganic elements such as aluminum (Al), iron (Fe), sulfur (S), calcium (Ca), potassium (K), and magnesium (Mg). These elements are components that contribute to adjusting the chemical properties of the soil and stabilizing the plant growth environment, and are characterized by the fact that multiple elements coexist in a naturally derived balance.

[0069] Furthermore, trace elements such as manganese (Mn), vanadium (V), strontium (Sr), zirconium (Zr), and zinc (Zn) have also been detected. These are thought to be components that affect plant metabolic functions, enzyme activity, and the microbial flora in the soil. In particular, elements such as vanadium and strontium are often not present in or are present in extremely small amounts in general single-component fertilizers and conventional soil conditioners, indicating a characteristic component composition of the mineral material according to the present invention.

[0070] Furthermore, as shown in Table 2, the mineral material in this embodiment also contains water and organic components. As a result, compared to materials consisting only of inorganic minerals, it is expected to improve water retention and aeration in the soil, as well as aid in the formation of granular structure.

[0071] Thus, the seaweed fossil-derived mineral material according to this embodiment is a multi-element material containing various inorganic and trace elements in naturally derived forms. Unlike conventional chemical fertilizers and soil conditioners consisting of limited components, it is possible to comprehensively improve the physical, chemical, and biological properties of the soil.

[0072] Next, Table 3 shows the results of a metal element content test conducted on the seaweed fossil-derived mineral water obtained by the manufacturing method of Example 2.

[0073] [Table 3] This test was performed using semi-quantitative analysis with ICP-MS, with a limit of quantification of 0.02 mg / L. Only elements detected at concentrations of 0.02 mg / L or higher were included. The content shown in Table 3 represents the measurement results for dissolved metallic elements and inorganic components.

[0074] As shown in Table 3, the mineral water derived from seaweed fossils in this embodiment contains dissolved major inorganic components such as silicon (Si), sulfur (S), calcium (Ca), sodium (Na), magnesium (Mg), and potassium (K). These components are essential nutrients necessary for plant growth and are characterized by their presence in a form that is easily absorbed quickly when applied as a foliar spray or to the soil.

[0075] Furthermore, trace elements such as aluminum (Al), vanadium (V), strontium (Sr), rubidium (Rb), and molybdenum (Mo) have also been detected. These are often not present in typical drinking mineral water or single-component fertilizers, or are present in extremely small amounts. In particular, elements such as vanadium and strontium have been suggested to be involved in plant metabolic functions and enzyme activity, and thus form the characteristic component composition of the mineral water according to the present invention.

[0076] Furthermore, the mineral water derived from seaweed fossils according to this embodiment showed a relatively high evaporation residue value of 1,480 mg / L, which indicates that various inorganic components and trace components contained in seaweed fossils are efficiently dissolved into the water by the manufacturing method according to the present invention.

[0077] Thus, unlike conventional mineral waters consisting of a single or few components, the seaweed fossil-derived mineral water according to this embodiment is a multi-element aqueous solution containing various inorganic and trace elements in a naturally derived balance. For this reason, it is effective as a means of supplying minerals to crops with a rapid effect through foliar spraying, bark spraying, or soil irrigation.

[0078] The components and their contents shown in Table 3 are examples only and may vary depending on the type of seaweed fossil used as raw material, mining conditions, boiling conditions, etc. However, the fact that the seaweed fossil-derived mineral water according to the present invention contains multiple inorganic elements and rare metals remains unchanged.

[0079] Table 4 shows the results of a quantitative analysis (vanadium content test) of the metal element content of the seaweed fossil-derived mineral water obtained by the manufacturing method of Example 2. As a comparative example, Table 5 shows the results of measuring the vanadium content of several commercially available mineral waters. This analysis was a quantitative analysis by ICP-MS, which accurately measured the content of metal elements dissolved in the seaweed fossil-derived mineral water. [Table 4] [Table 5]

[0080] As shown in Table 4, the mineral water derived from seaweed fossils according to this embodiment was confirmed to contain vanadium (V) at a concentration of approximately 0.73 mg / L. Vanadium is an element that exists in trace amounts in nature, and its detection level is often extremely low in general drinking water and groundwater. However, according to the manufacturing method of this embodiment, natural mineral components derived from seaweed fossils can be efficiently dissolved into the water, allowing for stable inclusion at a relatively high concentration.

[0081] Furthermore, the hydrogen ion concentration of the seaweed fossil-derived mineral water according to this embodiment is slightly alkaline, with a pH of approximately 8.3 to 8.4, and possesses the characteristic of being able to act as a buffer against acidic soil and plant growth environments. In addition, water quality tests have confirmed that each component is below the predetermined standard values, and the water quality is suitable for drinking.

[0082] On the other hand, as is clear from the data in Table 5, which is shown as a comparative example, the amount of vanadium contained in commercially available mineral water is generally limited to a few μg / L to at most a few tens of μg / L, which is more than an order of magnitude lower than the vanadium content of the seaweed fossil-derived mineral water according to this embodiment (approximately 0.73 mg / L). From this, it can be seen that the seaweed fossil-derived mineral water obtained by the manufacturing method according to the present invention is clearly different from conventional commercially available mineral water in terms of component concentration and component characteristics. Note that the data in Table 5 is an example of the results of measurements taken on mineral water that is generally available on the market, and is not limited to any specific brand or product.

[0083] Based on the above, the seaweed fossil-derived mineral water according to the present invention is water that can contain a wide variety of natural mineral components, including vanadium, in high concentrations and stably through a unique manufacturing process using seaweed fossils as raw materials. It has been shown to have properties that make it usable not only for soil improvement and foliar spraying on plants, but also for drinking. [Explanation of symbols]
