Description

  The present invention relates to a biodegradable fertilizer container, and more particularly to a fertilizer container that can be easily packed with fertilizer, easily carried, stabbed into the soil, and easily fertilized.

  In the fields of agriculture, horticulture and gardening, it is usually necessary to apply fertilizer appropriately for growing plants. In particular, when the plant grows over a long period of time, fertilization is performed on a wide range continuously and regularly when the plant growth area is large.

  Conventionally, as a method of fertilizing a plant having a long-term growth of a tree or the like, a method of regularly spraying fertilizer directly around the trunk (stem) of the plant is common. The spraying position varies depending on the thickness of the stem (stem) of the plant, and the thicker the stem (stem), the farther from the trunk (stem). Therefore, depending on the weather after fertilization, the fertilizer may be blown away or washed away by wind and rain, and the plant may not be sufficiently distributed. Further, since the fertilizer is exposed on the ground surface, there is an unsightly appearance such as mold growth, and the odor of the fertilizer can also be a problem. In addition, plants that require long-term fertilization not only deal with scattering by wind and rain, but also result in regular or frequent fertilization, which requires labor and increases costs.

  In order to prevent scattering due to wind and rain, when fertilizing, as the thickness of the stem (stem) increases away from the periphery of the stem (stem), a glass cup size is appropriately placed at the position considered to be the upper part of the root. There are also methods of digging holes, adding fertilizer, and applying soil. In this case, while holding the fertilizer in a heavy bag, it is necessary to move around the trunk (stem) of the plant and dig a hole, add fertilizer, or apply soil. Don't be. Therefore, fertilization takes time and effort, and in the agricultural field, long work is heavy labor. Further, when digging a hole, there is a risk of damaging the roots (root hairs, etc.) of the plant. In addition, since there is a large amount of fertilizer at the top of the plant roots and given rapidly, there is also a risk of adverse effects such as root burning (root withering).

  Therefore, there is a demand for means that allows easy maneuvering of the fertilizer even when fertilization is performed over a wide area, and that facilitates the work.

  The present invention was made to solve the above-mentioned problems of the prior art, and the effect of fertilizer is not impaired by wind and rain, etc., and it is easy to carry the fertilizer. An object of the present invention is to provide a fertilizer container that can be carried out easily and at low cost.

  For the above purpose, the present inventor completed the following fertilizer container. That is, a fertilizer container embedded in soil, having a container body in which a space for filling with fertilizer is formed, and a through-hole provided through the container body, It is a fertilizer container made of materials that decompose in soil.

  Preferably, the fertilizer container uses a biodegradable resin, and the container body has a pipe shape. The pipe-shaped tip (tip when buried in soil) is used to promote the dissolution of fertilizer, outflow, and decomposition and collapse of the container, so as not to impair the strength when stabbed into the soil (driving). A hole having a size that prevents the built-in fertilizer from coming out is appropriately provided.

  In addition, for the purpose of promoting the elution and outflow of fertilizer, a flat hole is formed on the side opposite to the tip, so that the built-in fertilizer does not come out, and there are holes for air and moisture distribution. There are several places. The elution or outflow timing of the built-in fertilizer can be adjusted by adjusting the opening and closing of the holes for circulating air and moisture with a hermetic seal or the like.

  The fertilizer container preferably has a structure that can be divided so that a fertilizer operator can easily pack (put) the fertilizer.

  If the fertilizer container of the present invention is used, since the fertilizer will not be dissipated due to wind and rain, the fertilizer can be given to plants without waste. Furthermore, it is easy to carry in a state filled with fertilizer, is easy to remove, and can be easily stabbed into the soil (dried) and fertilized. In addition, there is less concern about rough hands when fertilizing. At the same time, it rarely damages the roots of plants. In addition, by providing a structure in which the container can be divided, a desired type of fertilizer can be easily packed (put). Therefore, efficient fertilization can be performed and the cost can be reduced. Further, since the fertilizer is filled in the container and buried in the soil, the fertilizer is not conspicuous in appearance and the odor of the fertilizer does not become a problem.

It is sectional drawing along the longitudinal direction of the container for fertilizers concerning this invention. It is the figure which showed the end used as the rear end when the container for fertilizers of FIG. 1 is embed | buried in soil.

  Hereinafter, preferred embodiments of the fertilizer container will be described. However, the following is a preferable example, which is formed of a material that decomposes in the soil over time, i.e., a biodegradable material, can be filled with fertilizer, and is used by being embedded in the soil and gradually eluting the fertilizer or Changes can be made if the points that can be drained are met.

  Referring to FIG. 1, the fertilizer container embedded in the soil is provided with a container main body 11 in which a space 50 for filling fertilizer is formed and the container main body 11 penetrating. It has the 1st through-hole 22 and the 2nd through-hole 32 (through-hole), and is formed with the material which decomposes | disassembles in soil with time, ie, a biodegradable material. Details will be described below.

  In FIG. 1, the fertilizer container 10 is composed of a container body 11 having a space 50 for storing fertilizer, and is generally cylindrical (bar-shaped) as a whole so as to be easily stabbed (dried) into the soil. The fertilizer container 10 is not limited to a cylindrical shape, and may be a polygonal prism such as a triangular prism or a quadrangular prism. The fertilizer container 10 has a first through hole 22 and a second through hole 32 provided through the container body 11 in order to promote the decomposition of the container body 11. The container body 11 has a first through hole 22 through which a fluid such as water or air flows into one end on the side that becomes the rear end when buried in the soil, that is, the flat surface of the first end 23. is doing. In addition, the container main body 11 is used for fertilizer and moisture to flow out to one end on the side that becomes the tip when buried in soil, that is, to the bottom of the cone of the second end 33, and for microorganisms to enter. Two through holes 32 are provided. The first through hole 22 and the second through hole 32 allow water and air to flow in or out, and are in a general form of granular fertilizer (typically 1.8 to 2.0φ, 2.0φ The size, shape, and number are not particularly limited as long as they do not come out and do not impair the strength at the time of driving. Fertilizers that pass through the first through-hole 22 and the second through-hole 32 provided through the container body 11, for example, granules smaller than usual (less than 1.8φ), powder, paste, When filling the space 50 with fertilizer such as jelly, the first through hole 22 and the second through hole 32 of the space 50 have a biodegradable filter function such as cotton (cotton) or cotton cloth. Stuff and fill these fertilizers. The container body 11 is formed of a material that decomposes over time. As a material that decomposes over time, a biodegradable plastic described later is suitable.

  The said container main body can be divided | segmented into plurality, and it is comprised so that it can combine again. In the present embodiment, the container body 11 is divided into a first member 21 and a second member 31 that are fitted to each other in order to fill the space 50 with fertilizer. In order to recombine the divided container main body 11, the first member 21 has a fitting portion 24 in which a part of the outer periphery of the open end is cut, and the second member 31 is fitted with the open end of the open end. It has the fitting part 34 by which a part of inner periphery was shaved. The fitting part 24 and the fitting part 34 are fixed to each other by insertion. This is because when fitted in this way, the strength is easily maintained at the time of piercing (driving), and workability at the time of filling (putting) fertilizer and fitting is good. The positions of the fitting portions 24 and 34 between the first member 21 and the second member 31 are not necessarily the end of the cylindrical portion of the fertilizer container as long as the fertilizer can be filled. However, considering the plastic molding process, it is preferable to divide into shapes that can be molded at as low a cost as possible. Moreover, the container main body 11 is not restricted to two, You may divide | segment into three or more members, and when using three or more members, it is convenient for the length adjustment of the fertilizer container. Moreover, although it is preferable to form the 1st member 21 and the 2nd member 31 so that it may be fitted by insertion, from a viewpoint of ensuring the intensity | strength of the fertilizer container for driving in, it is not limited to this. They may be fixed to each other by screwing or interference fit.

  One end of the container body 11 on the side that becomes the tip when embedded in the soil, that is, the second end 33 is formed in a conical shape. This is because the conical shape is convenient for driving into the soil. However, the 2nd end 33 should just be a shape with little resistance with respect to implantation (stab) in soil, and may be not only a cone but a polygonal pyramid, such as a triangular pyramid and a quadrangular pyramid.

  One end of the container body 11 on the side that becomes the rear end when embedded in the soil, that is, the first end 23 is formed flat, and the first through hole 22 is formed in the flat surface of the first end 23. A flange portion 25 protruding from the flat surface of the first end 23 is formed so as to surround the first through hole 22. The flange portion 25 surrounds the first through hole 22 along the periphery of the end surface of the first end 23, and protrudes from the flat surface in the longitudinal direction of the fertilizer container 10. The flange portion 25 plays a role as a water receiver when it rains. The fertilizer container 10 can also be driven obliquely into the slope, and the flange portion 25 also functions as a water receiver at that time, and the water accumulated in the flange portion 25 can flow from the first through hole 22. Further, when the fertilizer container 10 is embedded in soil, the flange portion 25 can be hit with a hammer or the like. As the size of the fertilizer container 10 increases, it is appropriate to bury the fertilizer container 10 with a hammer or the like rather than inserting the fertilizer container 10. In that case, it is preferable to form the fertilizer container 10 so as to increase the strength of the tip portion particularly so as not to cause cracks. This can be dealt with by forming the container body 11 thick. The wall thickness of the container main body 11 can be selected as appropriate depending on conditions such as the material and size of the fertilizer container 10 and the hardness of the soil.

  FIG. 2 is a view of the first end 23 as seen from the top when it is buried in the soil (the sealing material 26 is removed). The first end 23 is provided with a flange portion 25 at the periphery, and a plurality of first through holes 22 partitioned by a radial rod-like portion 27 and a ring-like portion 28 are provided therein. However, the shape of the first end 23 shown in FIG. 2 is an example, and the present invention is not limited to this.

As a material which decomposes | disassembles in soil over time which comprises the container main body 11, biodegradable plastic other than natural materials, such as a bamboo cylinder, is suitable. Biodegradable plastics that can be used in fertilizer containers are not particularly limited as long as they are biodegradable, but when they come into contact with soil, they begin to degrade rapidly under aerobic and / or anaerobic conditions due to the action of microorganisms. It is preferable that the fertilizer container after decomposition is easily decomposed even if it flows into groundwater, rivers, etc .; and even if the fertilizer container fragments remain in the soil, it does not adversely affect agricultural work or the environment. . For this reason, the biodegradable plastic preferably satisfies at least one of the following characteristics.
(1) The relative biodegradation rate under aerobic conditions at 15 days is 30% or more;
(2) The relative biodegradation rate under aerobic conditions at 28 days is 50% or more; and (3) The relative biodegradation rate under anaerobic conditions at 120 days is 50% or more.

  In this specification, “relative biodegradation rate under aerobic conditions” means biodegradation of aniline, which is a standard target substance, in a predetermined time when tested in the biodegradability test (MITI method) of the Chemical Substances Control Law. It means the relative biodegradation rate under aerobic conditions when the rate is 100. The relative biodegradation rate under the aerobic condition is preferably 30% or more, more preferably 40% or more, particularly preferably 50% or more in 15 days. Alternatively, the relative biodegradation rate under aerobic conditions at 28 days is preferably 50% or more, more preferably 60% or more, and particularly preferably 80% or more. “Relative biodegradation rate under anaerobic conditions” is determined according to ASTM D. It means a relative biodegradation rate when the biodegradation rate at 120 days of cellulose, which is a standard target substance, is defined as 100 when tested by the test method of 5511-94. The relative biodegradation rate under the anaerobic condition is preferably 50% or more, more preferably 60% or more, and particularly preferably 70% or more.

  Preferred examples of biodegradable plastics having the above-described properties include polyhydroxybutyrate / valerate, polycaprolactone, polybutylene succinate, polybutylene succinate / adipate, polyethylene succinate, polyethylene succinate / adipate, poly Butylene succinate / terephthalate, polybutylene adipate / terephthalate, polyester carbonate, polylactic acid, polyglycolic acid, polydioxanone and poly (2-oxetanone), starch, modified starch, cellulose, chitin, chitosan, gluten, gelatin, casein, soy protein Collagen, keratin and natural rubber, polyethylene glycol, polyvinyl alcohol, polymalic acid and the like. Further, in addition to the above examples, other aliphatic polyesters are also preferable in view of having excellent processability and economy and being available in large quantities, and more preferably, aliphatic dicarboxylic acids having 2 to 6 carbon atoms. An aliphatic polyester obtained from the component and an aliphatic glycol component having 2 to 4 carbon atoms is used. These aliphatic polyesters are not particularly limited as long as they have biodegradability, and publicly known aliphatic polyesters can be used. Preferred examples thereof include JP-A-7-252354 and JP-A-9-71641. And the like disclosed in the above. Of these, polyethylene succinate, polyethylene succinate / adipate, polybutylene succinate, and polybutylene succinate / adipate are preferred. Polyethylene succinate and polyethylene succinate / adipate are more preferred. This is because these resins have a high biodegradability rate under both aerobic and anaerobic conditions, and exhibit good biodegradability even in activated sludge. Moreover, since it does not decompose and disintegrate depending on water and starts to decompose and disintegrate by the action of microorganisms, it is preferable because decomposition starts only when buried in the soil. Of the above, polyethylene succinate is particularly preferred. In addition, blends of biodegradable plastics and natural products such as starch, modified starch, cellulose, chitin, chitosan, gluten, gelatin, zein, soy protein, collagen, keratin are also particularly preferably used in the present invention. The The biodegradable plastic can be appropriately selected according to the desired biodegradation rate in consideration of the application. For example, polyethylene succinate and polyethylene succinate / adipate are particularly preferred for the purpose of fertilizer containers having a high biodegradation rate. Further, the blending ratio of polyethylene succinate and / or polyethylene succinate / adipate and natural product is not particularly limited as long as it can exhibit sufficient biodegradability, but polyethylene succinate and / or polyethylene succinate / Preferably it is 1-900 mass parts with respect to 100 mass parts of adipate, More preferably, it is 20-300 mass parts. Of these, polybutylene succinate / adipate is particularly preferred for the purpose of a fertilizer container with a slightly high biodegradation rate; when it is intended for a fertilizer container with a slightly slow biodegradation rate, Polybutylene succinate is particularly preferred; polylactic acid is particularly preferred for purposes of fertilizer containers with slow biodegradation rates. In addition, since the said biodegradable plastic is aliphatic polyester, mixing (blending) is very easy, and manufacture of the fertilizer container 10 becomes easy.

  Alternatively, commercially available biodegradable plastics may be used. Examples of such commercially available products include the product name Bionore manufactured by Showa Polymer Co., Ltd., the product name GS-Pla manufactured by Mitsubishi Chemical Corporation, the product name Matterby manufactured by Nippon Synthetic Chemical Industry Co., Ltd., and the product name Lacti manufactured by Shimadzu Corporation. , Mitsubishi Gas Chemical Co., Ltd., trade name Iupek, Cargill Dow, trade name Nature Works, Mitsui Chemicals, trade name Lacia, Daicel Chemical Industries, trade name Cell Green and trade name Placel (PCL), Monsanto Product name Biopol, BASF product name Ecoflex, DuPont product name Biomax, Eastman Chemical product name Easter Bio, Nippon Shokubai Co., Ltd. product name Lunar, Chisso product name Novon, product name Biogreen manufactured by Mitsubishi Gas Chemical Co., Ltd., product name Lactron manufactured by Kanebo Gosei Co., Ltd., manufactured by Dainippon Ink & Chemicals, Inc.

In addition, these biodegradable plastics may be used alone or in a blend of two or more. Among these, the trade name Bionore manufactured by Showa Polymer Co., Ltd. and the product name Lunare manufactured by Nippon Shokubai Co., Ltd. have a high decomposition rate and are suitable for the construction of the fertilizer container 10. By changing the mixing ratio of the plurality of biodegradable plastics and mixing them, the decomposition or disintegration speed of the container can be adjusted.

  Further, the first through hole 22 of the container body 11 is blocked by a peelable seal material 26 when delaying the elution and outflow timing of the fertilizer. The first through hole 22 is located on the side that becomes the rear end when the fertilizer container 10 is embedded in the soil, and even if the fertilizer container 10 is embedded, it is usually exposed to the ground surface. It is easy to peel off the sealing material 26. The sealing material 26 is used in a state where it is applied to the fertilizer container 10 only when the fertilization effect is intentionally delayed, but it should be used in a partially peeled state, for example, by perforating partly. You can also. The sealing material 26 can be peeled and can prevent water or air from flowing through the through hole for several weeks to several months, and is not particularly limited as long as it has a certain level of water resistance. However, a biodegradable sealing material is preferable from the viewpoint of not placing a burden on the environment. As a material for the biodegradable sealing material, a material obtained by forming the biodegradable plastic into a film can be preferably used. In addition to biodegradable plastics, for example, paper materials such as coated paper, foil paper, impregnated paper coated with adhesive, or sealing materials such as polyester film coated with adhesive, synthetic paper, etc. are naturally decomposed. It is also possible to use general-purpose products that can be used.

  The fertilizer container 10 is used as follows. First, the fitting portion 24 of the first member 21 and the fitting portion 34 of the second member 31 are removed, the space 50 is filled with fertilizer, and the fitting portions 24 and 34 are fitted again and fixed to each other. Next, the second end 33 having a conical shape is used as a tip, and at a desired place so that the flange portion 25 is piled, it is stabbed into the soil in a substantially vertical (right angle) direction with respect to the root of the plant in the soil. ) Embed the entire fertilizer container in the soil as deeply as possible. At this time, the rear end of the fertilizer container and the flat first end 23 are substantially the same height as the ground surface, and the first through hole 22 is substantially exposed. Normally, the fertilizer filled in the space 50 flows out or elutes into the soil from the second through hole 32 due to the influence of soil moisture, soil microorganisms, and the like. Further, due to rain flowing in from the first through hole 22, the filled fertilizer flows out or elutes from the second through hole 32 into the soil, and the fertilization effect is exhibited.

  Since the fertilizer container 10 has a structure that can be divided, the fertilizer can be easily packed (put). Specifically, after removing the first member 21 and the second member 31 as described above and filling the space 50 with the fertilizer, the first member 21 and the second member 31 may be fitted again. If the necessary number of fertilizer containers 10 are preliminarily packed with fertilizer, they can be carried to the fertilization position in the state of the container, and thus there is no need to carry a heavy fertilizer bag as in the prior art. Furthermore, since the fertilizer container 10 can be easily inserted and driven in easily, fertilization work is simplified.

  When fertilizing, the fertilizer container 10 containing the fertilizer can be stabbed (injected) into the soil as it is, so that fertilization can be efficiently performed near the root of the plant (root). When the fertilizer container 10 is buried in this manner, the fertilizer is eluted or flows out from the second through hole 32 due to the influence of soil moisture, soil microorganisms, and the like. Moreover, rain or the like water flows from the first through hole 22 in the upper part of the container, and the fertilizer is eluted or flows out from the second through hole 32 to reach the root of the plant. Since the fertilizer is contained in the fertilizer container 10, the scattering of the fertilizer due to wind and rain, which has been a problem in the past, does not occur. At the same time, almost all of the buried fertilizer can exert its effect, and no waste of fertilizer occurs. Since the fertilizer inside the container gradually elutes or flows out into the soil from the second through hole 32 of the second end 33, the effect of the fertilizer can be obtained over a long period of time.

  As conventionally done, in the method of digging a hole in the upper part of the root of the plant and filling the fertilizer, the root may be damaged when digging the hole, but the fertilizer container 10 is buried by insertion (driving). Therefore, it rarely damages plant roots (root hair, etc.). In addition, conventionally, a large amount of fertilizer that has been dug and buried in the upper part of the roots of the plant is rapidly given, and thus root burning (root withering) may occur. However, if the fertilizer container 10 is used, since the built-in fertilizer is in the vicinity of the roots and gradually dissolves and penetrates into the soil, there is little adverse effect such as root burning, and the plant is efficiently Can supply nutrients to the roots

  Further, since the entire amount of the fertilizer is embedded in the soil, the fertilizer does not impair the appearance even when fertilized on ornamental plants. Further, when the fertilizer itself has an odor, the odor spreads all over when spread on the surface of the conventional soil, but the odor hardly poses a problem by embedding the fertilizer container 10 in the soil.

  In addition, the first through-hole 22 at the first end 23 of the fertilizer container 10 is usually not sealed, so that water and air begin to flow in addition to the effects of soil moisture and soil microorganisms, Fertilization effect is demonstrated by the selected fertilizer. On the other hand, when the sealing material 26 is blocked, water and air do not flow from the first through hole 22, and therefore the time when the fertilizer elutes or flows out from the second through hole 32 of the second end 33 can be delayed. .

  Biodegradable plastics begin to degrade by contact with microorganisms in the soil. By embedding the fertilizer container 10, microorganisms enter from the second through hole 32 of the second end 33 on the distal end side of the fertilizer container 10, and decomposition proceeds from the inside of the distal end portion of the container main body 11. If the sealing material 26 is peeled off, microorganisms also enter from the first through hole 22 at the rear end of the fertilizer container 10, and decomposition also proceeds from the inside at the rear end portion of the fertilizer container 10. Moreover, the decomposition rate of the container (biodegradable plastic) can be increased by mixing soil in the fertilizer to be filled. Degradation and disintegration of the container (biodegradable plastic) is due to enzymatic degradation (microbial degradation), which effectively acts on the root development of plants. If root development is good, the growth of the above-ground part of the plant is also good.

  Table 1 below shows examples of the intended use of fertilizer and the preferred size of the fertilizer container 10. In addition, the length in Table 1 shows the length of the longest part from the front-end | tip of the container 10 for fertilizers to a rear end. However, the following is an example, and other sizes can be adopted.

  There is no restriction | limiting in particular as a form of the fertilizer filled and used for the container 10 for fertilizers, Any of granular form, a powder form, a paste form, or a larger solid fertilizer can be used. Moreover, as a kind of fertilizer, desired fertilizers, such as oil cake, bone meal, bone ash, chicken manure, organic fertilizer, chemical fertilizer, compound fertilizer, can be used. For example, since nutrients that can be absorbed by plants are inorganic, it is useful as a fast-acting fertilizer if it is filled with a chemical fertilizer made of an inorganic substance. Since the organic fertilizer becomes an inorganic substance by microorganisms and can be absorbed by plants, it can be used by filling the fertilizer container 10 as a slow-acting fertilizer. The coated fertilizer takes into account the elution of nutrients according to the state of growth of the plant, and is used as a long-term effect type fertilizer that can supply nutrients for a long period of time. Thus, various fertilizers can be appropriately selected by the user, sometimes blended, and filled as fertilizers suitable for the plant to be fertilized. In particular, oil candy, chicken manure, and the like have a characteristic odor when sprayed on the ground surface, and the appearance such as mold growth becomes unsightly. Therefore, the fertilizer container 10 of the present invention is suitable for applying such fertilizer. Further, as a preferred method of use, the first member 21 can be colored, and the sealing material 26 of the through hole 22 of the first end 23 can be colored to be color-coded. It is convenient to distinguish the type of fertilizer incorporated in the space 50 by these.

  There are no particular restrictions on the plants to be fertilized. Fruit trees such as apples, pears, peaches, chestnuts, mandarin oranges, grapes, trees such as planted trees, garden trees, vegetable gardens such as eggplants, peppers, tomatoes, cucumbers, flower beds Can be used for pot planting, planters, bonsai, mini bonsai, etc. Fertilization can be efficiently performed by inserting or driving in a fertilizer container 10 filled with fertilizer near the root of the plant (root). Furthermore, if the fertilizer container 10 is used, the fertilizer does not touch the root directly, so that there is little damage to the root. In the case of indoor ornamental plants such as bonsai and potted plants, if the fertilizer container 10 is filled with oil candy, bone meal, bone ash, chicken manure, etc., the odor will not be noticed and the appearance of mold etc. Is not particularly noticeable and is particularly suitable.

  As a guideline of the position of fertilization (pricking (driving)) using the container described in Table 1 above, it is not limited to these, but as the plant stem (stem) becomes thicker, it separates from the stem (stem), It is preferable to stab (drive) the container (fertilizer) into a range where the branches (leaves) at the upper part of the trunk (stem) have spread. The standard for the amount of fertilization (sticking (driving)) (the number of containers) varies depending on the type of fertilizer built in, so the fertilization time and effect are different, so there is no standard, and it is difficult to specify uniformly. Therefore, the approximate amount of fertilization (the number of containers) is 2 to 2 for plants with a stem diameter of up to about 3 cm, with reference to the diameter, length, and main application of the containers listed in Table 1. It is thought that it is desirable to stab (inject) about 3 stems around the stem (stem), and to stab (inject) 3 or more plants into 4 cm or more plants.

  In the field of fruit tree cultivation or the like, the fertilizer container 10 filled with fertilizer and pasted with the sealing material 26 can be fertilized by being buried in the soil in advance during the so-called agricultural off-season. Since soil microorganisms usually become active when the temperature in the soil exceeds 20 ° C., the fertilizer container 10 remains in the soil for a longer period of time when the soil temperature is low. Utilizing this fact, for example, if the fertilizer container 10 previously filled with fertilizer is buried in the soil in autumn or early spring, fertilization can be performed without particularly working in a busy period.

  The fertilizer container 10 can be used by fertilizing a plant or filling a soil conditioner. For example, it can be used by filling a soil improver for solidifying the soil on a factory site or an inclined land. Solid soils such as powders containing hydroxyisoxazole, himexazole, flusulfamide, fluazinam, dazomet, thiazinyl, thiraum, thiophanate, tifluzamide, teclophthalam, tricyclazole, triclophosmethyl, etc. as active ingredients to prevent crop diseases It is also useful for filling with a disinfectant.
