Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a humate-containing material, and more particularly, to a liquid and a granular humate-containing material.

[0002]

2. Description of the Related Art Humate-containing materials have an effect of improving the growth environment of plants, such as improving physical properties of soil, increasing the growth of useful microorganisms in soil, and increasing fertilizer efficiency.
Since humic acid itself becomes a nutrient for plants, it is used as a soil conditioner, a soil power enhancer, a fertilizer, and the like. As such a humate-containing material, a humate-containing material containing a granulated humate powder and a liquid material are used. The liquid humate-containing material has an immediate effect because it easily penetrates into soil, and can be easily applied by appropriately diluting it according to the application and spraying it with a sprayer or the like.

[0003]

However, in the conventional liquid humate-containing material, the concentration of the contained humate is low, so that a sufficient plant growing effect may not be obtained. Therefore, a liquid humate-containing material having an improved plant growing effect is desired. Here, in order to obtain a sufficient plant growing effect, it is conceivable to use a large amount of a conventional liquid humate-containing material. However, when a large amount of humate-containing material is used, unnecessary organic and inorganic substances contained in the humate-containing material also remain and accumulate in soil, and humic acid is contained by these unnecessary organic and inorganic substances. The plant-growing effect of the salt-containing material is impaired. For this reason, it is not preferable to increase the use amount of the humate-containing material. It is also conceivable to remove unnecessary organic and inorganic substances contained in the humate-containing material from the humate-containing material in order to increase the amount of use of the humate-containing material. It is not preferable because it is connected.

[0004] On the other hand, liquid humate-containing materials are easy to penetrate into soil and have an immediate effect. On the other hand, useful components are easily diffused in soil and useful components are easily absorbed by plants. For this reason, depending on the application conditions and the like, a long-term sustainability of the plant growing effect may not be obtained. Therefore, when it is necessary to maintain the plant growing effect for a longer period of time, a powdery and particulate humate-containing material is used. Humidate-containing materials in the form of powder have a slow decomposition of humate,
The humate component is gradually absorbed into the soil, so that plant growth effects such as soil improvement, soil enhancement, and nutritional supplementation can be maintained over a long period of time. In such a particulate humate-containing material, coffee activated carbon powder and humate powder are used to obtain useful components necessary for the growth of plants, which are insufficient with the humate-containing material. A humate-containing material in the form of powder mixed with a body has been proposed.

Activated carbon generally becomes humic acid when decomposed by microorganisms in the soil, and because it is porous, it absorbs harmful gases in the soil. And has the effect of increasing the For this reason, the conventional granulated humate-containing material obtained by mixing coffee activated carbon and granulated humate is:
The plant cultivation effect can be enhanced as compared with the case where the humate-containing material in the form of a powder is used alone. However, if the plant cultivation effect can be further enhanced, its usefulness as a soil conditioner, a soil fertility enhancer, fertilizer, etc. will increase, and the amount of humate-containing materials will be reduced, so that the powdery and granular It is desired to improve the plant growing effect of humate-containing materials.

An object of the present invention is to improve the effect of humate-containing materials on plant growth.

[0007]

The humate-containing material of the present invention is obtained by dissolving 100 parts by weight of humate in water,
A concentration of at least one kind of alkaline earth metal of 0.001 to 0.5 parts by weight and at least one kind of polyvalent cation compound of 0.001 to 0.5 parts by weight is used. The above problem is solved by using a liquid humate-containing material containing not less than 30% by weight and not more than 30% by weight.

[0008] Such a liquid humate-containing material can increase the humate content and provide sufficient micronutrients necessary for plant growth, that is, sufficient elements essential for plant growth. Since the humate-containing material is contained in a large amount, the effect of growing the plant can be improved.

Further, using water as a solvent, 100 parts by weight of a humate, at least one kind of alkaline earth metal of 0.01 to 0.2 parts by weight, and 0.01 to 0.01 parts by weight of an alkaline earth metal. As a liquid humate-containing material having a concentration of at least one polyvalent cation compound of 2 parts by weight or less and a concentration of 10% by weight or more and 20% by weight or less, plant growth of the humate-containing material This is preferable because the effect can be further improved. Further, it is preferable to use ion water as the solvent, since the absorption rate of the useful component into the plant can be improved, and the plant growing effect can be further improved. In addition, in the above-mentioned liquid humate-containing material, if the humate is an alkali metal salt of humic acid, it is preferable because the humate can be easily dissolved in water. Furthermore, if the humate-containing material contains at least one kind of phosphorus compound in an amount of from 0.01 part by weight to 0.2 part by weight, a phosphorus compound useful as a fertilizer is used.
This is preferable because the effect of growing plants can be further improved.

[0010] On the other hand, a humate-containing material in the form of a granule comprising coconut shell activated carbon granules and humate granules. With such a powdery and granular humate-containing material, coconut shell activated carbon, which is more porous and has a larger surface area than coffee activated carbon and contains more minerals than coffee activated carbon, can be used as a humate-containing material. Increasing the useful ingredients contained, absorption of harmful gases in the soil and further enhancement of microbial growth can be achieved, and the plant growing effect can be maintained for a longer period of time. Can be improved.

Further, a humate-containing material in the form of powder containing 100 parts by weight of coconut shell activated carbon powder and 10 to 100 parts by weight of humate powder. It also contains at least one kind of alkaline earth metal of 0.001 to 0.5 parts by weight and at least one kind of polyvalent cation compound of 0.001 to 0.5 parts by weight. It is a humate-containing material in the form of powder. This is preferable because the plant growing effect can be further improved.

[0012] Further, it contains coconut shell activated carbon powder and humate powder having substantially the same particle diameter, and the particle diameter distribution of the powder particles is less than 0.5 mm and 10% or more and 20% or less. 30% or more and 50% or less of a particle size of 0.5 mm or more and less than 1.0 mm,
When the humic acid-containing material is sprayed with a spraying device such as a cyclone when the particle diameter is 1.0% or more and 2.5mm or less is 25% or more and 50% or less, the humic acid-containing material is sufficiently dispersed with an appropriate particle diameter and weight to be sprayed. Is preferred. The humic acid salt is composed of at least one of an ammonium salt of humic acid and an alkali metal salt.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) Hereinafter, a first embodiment of a humate-containing material to which the present invention is applied will be described. In the present embodiment, a liquid humate-containing material used as a soil conditioner will be described as an example.

[0014] The soil conditioner may be used together with, for example, a fertilizer.
It is used to improve the soil to a soil environment where plants can grow easily, such as by spraying it several times a year.
Soil conditioners improve soil properties in order to improve the soil environment where plants can easily grow, in addition to improving the physical properties of the soil, improve the efficiency and sustainability of fertilizer, and provide nutrients and nutrients for plant growth. It is desired to have an action such as assisting absorption of micronutrients necessary for the physiological activity of plants. Humic acid, on the other hand, has the effect of preventing fertilizers such as nitrogen, phosphoric acid, and potash from binding to soil and being fixed to the soil, thereby preventing nutrients in the fertilizer from being hardly absorbed by plants. To improve the fertilizer effect by facilitating the absorption of nutrients and micronutrients in plants and soil, and to improve the soil permeability by promoting the formation of the aggregate structure of the soil, and furthermore, the distribution of air Has the effect of increasing the Furthermore, the soil having the aggregated structure improves water permeability and air circulation, thereby increasing the growth of plant roots, that is, the propagation of microorganisms useful for the growth of the entire plant. In addition, humic acid is a micronutrient necessary for plant growth, magnesium,
By complexing or chelating with alkaline earth metals such as calcium, polyvalent cations such as iron, sulfur, manganese, molybdenum, zinc and copper, these micronutrients can be easily absorbed by plants. Have. In this way, humic acid improves the soil environment physicochemically, promotes the growth of plant roots, and helps the plant absorb nutrients and micronutrients necessary for plant growth. It is suitable as.

As raw materials for obtaining humic acid, soil, young coals such as lignite and lignite, weathered coals, leonadites, peat, peat and the like can be used. When soil, leonadites, and coal are used as raw materials, humic acid is obtained as an alkali extract of humic acid by alkali extraction from these raw materials with an alkali metal solution such as sodium hydroxide or potassium hydroxide. ing. On the other hand, when raw materials such as lignite and lignite, and peat or peat are used as raw materials, these raw materials are oxidatively decomposed with nitric acid, and humic acid is extracted from these decomposed products by alkali extraction in the same manner as described above. Humic acid is obtained as an alkaline extract of acids. At this time, the pH of the alkaline extract of humic acid is adjusted to 9.0 or more in order to keep the humic acid dissolved.

When humic acid is obtained from raw materials, the above-mentioned raw materials such as soil, young coals, coals, leonadites, and peat or peat are pulverized into powders and granules. For example, humic acid can be obtained by separating into powder and granules containing humic acid and powder and granules composed of other components by using, for example, wind separation. Then, an alkali extract of humic acid can be obtained by alkali extraction from the humic acid powder in the same manner as described above. However,
When humic acid is obtained by this method, components other than humic acid in the raw material may be mixed in a large amount into the humic acid powder or the alkaline extract of humic acid. There is a possibility that the amount of the components unnecessary for the growth of the plant contained in the soil may increase. Therefore, it is preferable to carry out alkali extraction from the raw material or the oxidative decomposition product of the raw material. It is also possible to use an ammonia extract of humic acid obtained by extracting ammonia from raw materials or humic acid particles obtained from the raw materials. However, since humic acid has high solubility in alkali, it is easier to dissolve in a solvent by alkali extraction as in the present embodiment. Therefore, in producing the liquid humate-containing material as in the present embodiment, it is desirable to use an alkali metal salt of humic acid.

The humic acid thus obtained reacts with sodium or potassium of the alkaline solution used for the extraction to form a sodium or potassium salt of humic acid, that is, an alkali metal salt of humic acid in the alkali extract. include. When ammonia is extracted, it is contained in the ammonia extract as an ammonium salt of humic acid. As the humate used for the humate-containing material of the present embodiment, any one of the above-mentioned humic acid sodium salts, potassium salts, or ammonium salts may be used. A mixture of any two or all three of the above humates can also be used. Further, as the humate, an alkaline earth metal salt of humic acid obtained by extracting humic acid with an alkaline solution such as magnesium hydroxide or calcium hydroxide can be used. However, humic acid may be difficult to dissolve in an alkaline earth metal salt, and therefore, it is preferable to use an alkali metal salt.

The humate-containing material of the present embodiment is produced by suspending or dissolving the humate obtained by the above-described method and trace nutrients necessary for the physiological activity of plants using water as a solvent. Have been. That is, 100 parts by weight of a humate, 0.001 part by weight or more and 0.5 part by weight or less of an alkaline earth metal compound such as calcium or magnesium, and a polyvalent compound such as iron, manganese, molybdenum, zinc, or copper. Each of the cation compounds is suspended or dissolved in water in an amount of 0.0001 to 0.5 parts by weight, and the total concentration of the humate, the alkaline earth metal compound, and the polyvalent cation compound, that is, the solid content A liquid humate-containing material is manufactured by adjusting the concentration to 5% by weight or more and 30% by weight or less.

At this time, the alkaline earth metal compound and the polyvalent cation compound are water-soluble salts or inorganic compound salts, and specifically, nitrate compounds and salts of the alkaline earth metal compound and the polyvalent cation compound. Compounds, sulfate compounds,
Hydroxide compounds and the like. In addition, various compounds belonging to alkaline earth metal compounds and polycation compounds can be selectively contained. However, it is not possible to select a heavy metal compound that adversely affects plant growth.

Here, the ratio of one kind of alkaline earth metal compound and the ratio of one kind of polyvalent cation compound are as follows:
If each exceeds 0.2 parts by weight, humic acid may precipitate and become insoluble in water depending on conditions such as the pH and temperature of the liquid, which is a characteristic of the liquid humate-containing material. Immediate effect may be lost. Furthermore, the ratio of each of the alkaline earth metal compound and the polyvalent cation compound is
If the amount is more than 0.5 parts by weight, humic acid precipitates and becomes insoluble in water regardless of conditions. Therefore, the proportion of each of the alkaline earth metal compound and the polycation compound must be 0.5 parts by weight or less, and 0.2 parts by weight or less in order to surely prevent precipitation of humic acid. Is preferred. Further, the ratio of each of one kind of alkaline earth metal compound and one kind of polyvalent cation compound is 0.0.
If the amount is less than 01 parts by weight, the concentration of the trace nutrient is too low, which is not preferable. Therefore, the proportion of each of the alkaline earth metal compound and the polycation compound must be 0.001 parts by weight or more, and in order to contain a sufficient amount of micronutrients, the ratio is 0.01 parts by weight or more. Preferably, there is. As described above, the ratio of one kind of alkaline earth metal compound and one kind of polyvalent cation compound is 0.001 to 0.5 parts by weight with respect to 100 parts by weight of the humate. And preferably 0.01 part by weight or more and 0.2 part by weight.
Not more than parts by weight.

Further, if the total concentration of the humate, the alkaline earth metal compound and the polyvalent cation compound, that is, the solid content concentration is less than 5% by weight, the content of humic acid is undesirably reduced. Therefore, the solid content concentration must be 5% by weight or more, and preferably 10% by weight or more in order to contain sufficient humic acid. Further, when the solid content concentration is higher than 20% by weight, the properties of the humate-containing material may become viscous, and the humate-containing material may be difficult to handle at the time of use, such as difficulty in dilution. . If the solids content is higher than 30% by weight, the humate-containing material becomes almost completely viscous, which makes it difficult to dilute and deteriorates handling when the humate-containing material is used. Therefore, the solid content concentration must be 30% by weight or less, and is preferably 20% by weight or less in order to facilitate handling of the humate-containing material at the time of use. As described above, the solid content concentration is 5% by weight or more and 3% by weight or more.
It must be 0% by weight or less, preferably 10% by weight or more and 20% by weight or less.

The alkaline earth metal compound and the polyvalent cation compound to be added to the humate-containing material are appropriately selected according to the intended use of the humate-containing material, and at least one kind of the alkaline earth metal compound is used. And at least one polyvalent cation compound.

The liquid humate-containing material of the present embodiment contains each component in the distribution as shown in the above-mentioned production method. An example of comparing the ratio of the concentration of the components contained in the liquid humate-containing material of the present embodiment and the conventional liquid humate-containing material in a solution having substantially the same pH will be described. The proportion of solids contained in the humate-containing material is about 10 to 11% of the total, whereas the proportion of solids contained in the conventional liquid humate-containing material is about 8 to 10%. 9%. In the humate-containing material of this embodiment, about 9 to 10% of the solid content is humate, whereas in the conventional liquid humate-containing material, about 7 to 8 % Were humates. At this time, the content ratio of other components such as trace nutrients hardly changed or was slightly higher in the humate-containing material of the present embodiment. As described above, the proportion of the solid content of the humate-containing material of the present embodiment is higher than the proportion of the solid content of the conventional humate-containing material, and further, the humate-containing material of the present embodiment. Since the humate content ratio of the humate-containing material of the present embodiment is higher than the humate content ratio of the conventional humate-containing material, the increase in the solid content ratio of the humate-containing material of the present embodiment is almost zero. This is due to an increase in the humate content, and the humate-containing material of this embodiment contains more humate, that is, more humic acid than the conventional humate-containing material. .

As described above, since the liquid humate-containing material of the present embodiment contains more humic acid than the conventional humate-containing material, the ability to form a soil aggregate structure is increased. And, to further promote the growth of useful microorganisms in the soil, such as improving and maintaining a soil environment where plants can easily grow,
It can increase the growth of plant roots, that is, the effect of promoting the growth of the entire plant, the effect of assisting the absorption of nutrients and micronutrients required for plant growth into the plant, and improve the plant growing effect .

Furthermore, the action of improving and maintaining the soil environment in which the plant is easy to grow and the action of assisting the absorption of nutrients and micronutrients required for the growth of the plant into the plant, and the like, make the plant resistant to pests and the like. Can also be improved. Also,
Such an increase in the humic acid content is caused not only by the soil conditioner, but also by a soil strength enhancer that enhances the soil strength of the degraded soil, and the humic acid content as a nutrient is increased. The effect as a fertilizer to replenish the nutrients needed can also be increased.

In order to further improve the action of the humate-containing material of the present embodiment as a fertilizer, potassium humate and an ammonium salt are used as humates in order to increase the types of components used as nutrients. Is preferably used, and a phosphorus compound is preferably added as a component of the humate-containing material. When adding a phosphorus compound, it is preferable to add at least one kind of phosphoric acid compound in a total amount of 0.01 to 2.0 parts by weight based on 100 parts by weight of the humate. It is preferable to balance the amount. Note that as the phosphorus compound, various substances containing phosphorus such as phosphate, polyphosphate, and phosphate rock can be used.

Further, since the liquid humate-containing material of the present embodiment is in a liquid state and is easily diluted, it can be easily applied by appropriately diluting with water or the like and spraying. . In this embodiment, water is used as the solvent. However, ion water in which negative ions are generated in water using an ion generator or the like can be used. The effect of electrical action on plants has been known for a long time, and it is known that negative ions have an important effect on plant growth and have effects such as promoting growth and fruiting. . Therefore, by using ionic water as a solvent, the plant growing effect can be further improved.

(Second Embodiment) Hereinafter, a second embodiment of the humate-containing material to which the present invention is applied will be described. This embodiment is different from the first embodiment in that
It is another object of the present invention to provide a humate-containing material in the form of granules including coconut shell activated carbon granules and humate granules.

The humate obtained in the same manner as in the first embodiment is used as the powdery and particulate humate-containing material of the present embodiment. That is, an alkali metal salt or ammonium salt of humic acid obtained by alkali or ammonia extraction from a raw material or an oxide of the raw material,
An alkali metal salt or ammonium salt of humic acid obtained by alkali extraction or ammonia extraction from a humic acid powder obtained by pulverizing a raw material can be used. further,
It is also possible to use the humic acid powder itself obtained by pulverizing the raw material. However, similar to the first embodiment, in the case of humic acid powder obtained by pulverizing raw materials, or an alkali metal salt or ammonium salt of humic acid obtained by extraction from this humic acid powder Since the ingredients other than humic acid in the raw materials may be mixed in the humic acid granules, the amount of components unnecessary for the growth of plants contained in the final product humate-containing material increases. there is a possibility. Therefore, it is preferable to use at least one of an alkali metal salt of humic acid and an ammonium salt of humic acid obtained by performing alkali extraction or ammonia extraction from a raw material or an oxidative decomposition product of the raw material. Furthermore, by using a humic acid salt obtained by performing an alkali extraction or an ammonia extraction from the raw material or the oxidized decomposition product of the raw material, the humic acid-containing material is a component useful for growing plants such as nitrogen, sodium,
Since potassium and the like can be contained, it is preferable to use a humic acid salt obtained by mixing an alkali metal salt of humic acid and an ammonium salt of humic acid. Since the humate obtained by alkali extraction or ammonia extraction is in the form of an alkali extract or an ammonia extract, the water content of these extracts is evaporated to form a humate powder having an appropriate particle size. Used after granulating into granules.

By mixing the humate obtained by such a method with coconut shell activated carbon, a powdery humate-containing material is produced. The particulate humate-containing material of the present embodiment is obtained by mixing humate and coconut shell activated carbon in a ratio of approximately 1: 3. To achieve such a ratio, the humate powder is mixed in an amount of 10 to 100 parts by weight with respect to 100 parts by weight of the coconut shell activated carbon powder. In the powdery and particulate humate-containing material of the present embodiment, the particle size distribution of the powdery and granular materials constituting the humate-containing material is 0. 10% or more and 20% or less for less than 5 mm, particle size 0.5 mm
30% or more and 50% or less for particles having a particle size of 1.0 to less than 1.0 mm.
The particle size and particle size distribution of the coconut shell activated carbon and the humate are selected and used so that the range from 25 mm to less than 2.5 mm falls within the range from 25% to 50%.

The coconut shell activated carbon is obtained by baking a coconut shell portion into charcoal. Coconut shell activated carbon has a porous structure like other activated carbon such as coffee activated carbon,
The surface area of coconut shell activated carbon is about 50 with 1 g of coconut shell activated carbon.
0～1000M ² There, the surface area compared with other activated carbon such as coffee activated carbon is about 500 meters ² or less per 1g is rich in large porosity. Such coconut shell activated carbon, which is more porous than other activated carbons and has a large surface area, has higher water retention, water permeability, air permeability, adsorptivity and the like than other activated carbons. Furthermore, about 3% of the weight of the coconut shell activated carbon is ash, and the ash contains minerals. The minerals in the ash are present as carbonates, are easily soluble in water, and thus easily penetrate into soil, and are easily absorbed by plants. In addition, coconut shell activated carbon is converted to humic acid by the action of decomposing microorganisms in the soil.

The powder of coconut shell activated carbon having the above characteristics and the powder of humate having the characteristics described in the first embodiment are mixed in the ratio and particle size distribution of the present embodiment. In the particulate humate-containing material, the humate in the particulate form is gradually decomposed, so that the plant cultivation effect is maintained for a long time, and the activated carbon of the coconut shell is gradually decomposed by microorganisms. By the generation of humic acid, humic acid generated from coconut shell activated carbon is supplemented even when the amount of humate in the form of powder has been reduced.
For this reason, the plant growing effect of the humate can be maintained for a longer period of time.

Further, in addition to the water retention, water permeability and air permeability obtained by the aggregated structure of the soil formed by humic acid, the water retention obtained by the coconut shell activated carbon having a structure more porous than other activated carbons Water permeability and air permeability can further improve the water retention, water permeability and air permeability of the soil. In addition, by further improving water retention, water permeability, and air permeability, it is possible to improve effects such as promotion of growth of useful microorganisms in soil and growth of plant roots. in addition,
The higher adsorption effect of the coconut shell activated carbon having a larger surface area than other activated carbons can enhance the removal effect of harmful gases in the soil.

As described above, in the powdery and particulate humate-containing material of the present embodiment, by using coconut shell activated carbon, plant cultivation is higher than that of the conventional powdery and particulate humate-containing material containing coffee activated carbon. The effect can be obtained, and the plant growing effect can be improved by the synergistic action of the plant growing effect of the coconut shell activated carbon and the plant growing effect of the humate.

By the way, when a powdery or particulate humate-containing material is sprayed over a large area such as a golf course, the powdery or particulate humate-containing material is scattered over a wide area using centrifugal force or the like. A spraying device such as a cyclone for spraying is used. However, the conventional powdery and particulate humate-containing material, whether containing activated carbon or not containing activated carbon, has a small particle size, so that the humate-containing material does not fly well and is scattered. The device does not allow efficient spraying of the humate-containing material without variability.

On the other hand, in the powdery and particulate humate-containing material of the present embodiment, since the particle size distribution of the powdery material constituting the humate-containing material is in an appropriate range, the coconut shell activated carbon is not used. The granules and humate granules have an appropriate size and weight, and can be efficiently sprayed over a wide range without unevenness by a spraying device.

In the powdery and particulate humate-containing material, only coconut shell activated carbon and humate were mixed.
Similarly to the embodiment, in order to add the micronutrient to the humate-containing material, a granulated alkaline earth metal compound and a granulated polyvalent cation compound can be mixed. At this time, at least one kind of alkaline earth metal compound is 0.001 to 0.5 parts by weight, and at least one kind is 0.001 to 0 parts by weight with respect to 100 parts by weight of the humate powder. Mix not more than .5 parts by weight.
Further, when used as a fertilizer, a phosphorus compound which becomes a nutrient can be added.
At least one phosphoric acid compound is used in an amount of 0.1 part by weight based on parts by weight.
It is added in an amount of from 01 parts by weight to 2.0 parts by weight.

Example 6 NK fertilizer (nitrogen: potassium =
2: mixed fertilizer 1.5) as in Example 4 respectively and granular material like humic acid salt-containing material of the same invention as 1 m ² per 2
Applied at 0 g, P fertilizer (phosphate fertilizer) were applied at 1 m ² per 10 g 5 days after the application of NK fertilizers and humic acid salt-containing material.

(Comparative Example 3) A conventional powdery and granular humate-containing material obtained by mixing coffee activated carbon powder and humate powder in a ratio of approximately 1: 3 is 1 m. 20 g per ² and NPK fertilizer were applied simultaneously at 45 g per m ² .

Comparative Example 4 NK fertilizer (nitrogen: potassium =
2: fertilizer mixed with 1.5) and Comparative Example 3 each the same as the conventional powdery grains like humic acid salt-containing material and 1 m ² per 20
g of NK fertilizer and humate-containing material
The P fertilizer (phosphoric acid fertilizer) was applied at 1m ² per 10g a day later.

[Table 4] As described above, the weight of the foliage and the weight of the root are increased when the particulate-form humate-containing material of the present invention is used, compared to the case where the conventional particulate-form humate-containing material is used. It can be seen that the synergistic effect of the coconut shell activated carbon and the humate salt enables the powdery and granular humate-containing material of the present invention to improve the plant growing effect. In particular, an increase in root weight leads to an increase in nutrient absorption, and promotes the growth of the whole plant. In addition, in cultivation of fruit trees, the sugar content of fruits can be increased by increasing the weight of roots. Moreover, the plant cultivation effect can be enhanced by applying the humate-containing material several days after application of the NPK fertilizer, rather than simultaneously applying the NPK fertilizer and the humate-containing material. Furthermore, when the NK fertilizer and the humate-containing material are simultaneously applied and then the P fertilizer is applied several days later, the plant growing effect can be further enhanced.

It should be noted that N was added to the test soil to which lime was not added.
For wheat and soybean cultivated by applying only NPK fertilizer to the test soil to which lime was added, the weight of each of foliage and roots was about 10 It was about twice as heavy. Therefore, the weight of the standard foliage and root in the test soil to which lime is added is about 10 times heavier than the weight of standard foliage and root in the test soil to which no lime is added.
