DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a soil conditioner. More specifically, the present invention relates to a soil conditioner containing sulfur and humic acid as active ingredients.

[0002]

2. Description of the Prior Art Powdered elemental sulfur is used as a soil conditioner. Sulfur is an essential component of plants, and sulfate is usually used as fertilizer. When applied to soil, sulfur alone gradually changes to sulfuric acid, which acts on some microorganisms to promote nitrogen mineralization and lower the soil pH. Therefore, it is known that there are benefits and harms, and that this effect varies greatly depending on the type of soil, soil conditions, and sulfur application rate. That is, sulfur lowers soil pH,
Therefore, it is necessary to adjust the application depending on the crop. For crops that prefer weak acidity (pH 5.5-6.0) (potatoes, garlic, radish, etc.) and those that prefer slightly acidic (cucumbers, tomatoes, eggplants, green onions, Chinese cabbage, etc.), the amount of sulfur applied should be significantly changed. Is important, and its use requires caution, and measures have been desired.

[0003]

[Means for solving the problems] Humic ash is a humic substance that can be naturally formed in soil, and is already used as a soil conditioner and fertilizer. Will not come out. Humic Ashes is contained in a large amount in leonardite (sediment before it becomes lignite), and what is extracted and concentrated from this is used as humic acid fertilizers (decompose lignite to remove clay, lime,
(A salt of ammonium or the like) is different from the production method in that the effect on the plant appears in a small amount. Humic Ashes has a large base substitution capacity of 500 or more, reduces the fixation of nutrients by soil, and increases the absorption of nutrient water to plants. Further, Humic Ashes has an effect of promoting rooting, an effect of promoting absorption of trace elements such as iron, copper, and manganese by a chelating action, and an effect of reducing harm of a high concentration of nitrogen. The present inventors have found that when sulfur is mixed with Humic Acids, the above-mentioned problem of sulfur is alleviated, and a remarkable effect is observed in each crop compared with sulfur alone or Humic Acids alone.

[0004]

The present invention provides a soil conditioner composition comprising 99.99 to 80% by weight of sulfur and 0.01 to 20% by weight of Humic Acids. For the soil conditioner composition, zeolite, vermiculite, perlite, coconut shell chips, charcoal, coconut shell charcoal, peat moss, bark compost,
At least one of bentonite and diatomaceous earth can be mixed in an amount of 99% by weight or less based on the total composition. The soil conditioner of the present invention is preferably applied with a particle size of 5 mm or less, more preferably 4 mm or less.

[0005] The Humic Acids used in the present invention are those extracted and concentrated from Leonardite as described above, and those supported on liquids or powders are currently exclusively used in Mammoth International, Houston, Texas, USA. Provided by a chemical company. Accordingly, the Humic Assists used in the present invention are those provided by the company and equivalents thereof.

[0006]

Surprisingly, the addition of only 0.01% by weight of Humic Acids significantly overcomes the disadvantages of sulfur. It is presumed to represent some catalytic effect. By changing the ratio of sulfur and Humic Acids, various crops can be effective. Humic Ashes itself has a fertilizer effect, but 10wt
%, The synergistic effect with sulfur disappears,
If the content exceeds wt%, the effect of sulfur is rather attenuated. Humic Ashes itself has a fertilizer effect, but is expensive and has a preferred practical mixing ratio of 0.1.
01 to 10 wt%. 20 as a soil conditioner product
Application of ~ 100 kg / 10a is desirable.

[0007]

DETAILED DESCRIPTION OF THE INVENTION Hereinafter, the present invention will be specifically disclosed by examples. Table 1 shows the compositions of the samples used in the examples.
As shown in FIG.

The samples were prepared by mixing and mixing Humic Acids as shown in Table 1 with a mixture of sulfur and carrier in the proportions shown in the table. The carrier used was a mixture of only zeolite (only numerical values described) and a mixture of charcoal (wood), vermiculite (ba), and peat moss (pi) at the numerical values described. Sample 16 is a mixture of three types of charcoal, peat moss, and zeolite. Both the sulfur and the carrier were used under a 4 mm sieve.

Sulfur alone has a weak effect, but 50k
At g / 10a, growth is suppressed by a decrease in pH and an increase in EC. Even if Humic Acids alone is used, the effect is considerably exhibited, and 25 to 50 g / 10a is quite good. The combined use of sulfur and Humic Acids is recognized irrespective of the type of carrier, and significant effects are exhibited when sulfur is 10 to 20 kg / 10a and Humic Acids is 25 to 50 g / 10a. In this test, the standard was untreated and the leafy vegetable yield was 36.5 g.
Was set to 100.

Example 2 Use for Spinach Cultivation 1 kg of horticultural soil (used in Example 1) is filled in a plastic pot, and sample 1 'is 25, 50, 100, 250
Samples 3, 4, and 10 were applied in a total amount of 25, 50, and 125 g / 10a in terms of Humic Acids. Table 3 shows the results of sowing 5 spinach seeds and cultivating them for 45 days.

The effect of sulfur alone is not recognized in spinach which prefers a pH region close to neutrality, and the effect of Humic Acids is recognized, but the effect is remarkably remarkable when used in combination with a small amount of sulfur. Humic Ashes has the effect of alleviating the growth suppression caused by sulfur.

Example 3 Use for Potato Cultivation An a / 2000 pot was filled with 6 kg of Kuroboku soil, and a potato-specific composition (10-16-14) was applied in an amount of N: 1 g per pot in an entire layer. Sample 1 'is 25,
Samples 3, 4, and 10 are equivalent to 50, 100, and 250 kg / 10a.
Table 4 shows the results obtained by applying the whole layer so as to obtain an amount equivalent to g / 10a, transplanting potato seedlings and cultivating them for 60 days.

For potatoes that prefer a weakly acidic pH range, sulfur alone is effective. The effect of Humic Acids is also recognized, but the combined use with sulfur has a synergistic effect, and the effect is remarkable in Sample 10 containing a large amount of sulfur components.

The results of the interim results indicate that the harvest season is likely to be promoted.

The results of the day harvest are shown in Table 6. Although the effects are recognized in both cases, the sample having less sulfur has better results than the case of potato.
