Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soil improving material used for controlling grass such as greens on a golf course.

[0002]

2. Description of the Related Art Conventionally, a large amount of pesticides and fertilizers such as insecticides, herbicides, and bactericides have been used without interruption in order to protect lawn grass on golf courses from pests. In addition, the water retention capacity of the floor soil, breathability,
For improving physical and chemical properties such as water permeability and fertility, bark compost, organic soil improvers such as peat moss, inorganic soil improvers such as zeolite, perlite, and bentonite can be used alone or in various combinations. It is used.

[0003]

However, in using these conventional soil improving materials, it is necessary to use them properly according to the purpose of improvement, and a skilled green keeper is indispensable for managing grass. In addition, since the conventional soil improvers have insufficient ability to adsorb and retain pesticides,
Agricultural chemicals flow out due to rainfall, causing environmental pollution and wasteful use of agricultural chemicals.

The present invention improves physical and chemical properties such as water retention capacity, air permeability, water permeability, and fertilizing capacity of the floor soil by spraying it on the surface of the floor soil or adding it to the floor soil. Prevents the outflow of pesticides and prolongs the duration of pesticide efficacy,
It is intended to reduce the amount of agricultural chemicals used.

[0005]

The soil improving material of the present invention comprises:
The powder or granules of the zeolite-based composition are mixed with organic acid and
And treated with amino acids .

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION As the zeolite composition, both natural zeolite and synthetic zeolite can be used.

The zeolite composition may be used in the form of powder or granules. The granular zeolite-based composition can also be produced by using a powdery zeolite-based composition and a granulating agent such as Portland cement or carboxymethyl cellulose. Also, if necessary,
You may grind and classify. The particle size of the granular zeolite-based composition is preferably within the range of passing through a sieve with an opening of 10 mm and staying with a sieve with an opening of 0.5 mm.

The treatment of the zeolite-based composition with the organic acid may be carried out by directly or diluting the organic acid with respect to the zeolite-based composition and then spraying it in the form of an aqueous solution and drying, or by treating the zeolite-based composition in the organic acid. Can be carried out by immersing and then drying. The amount of the organic acid used depends on the pH of the zeolite composition and the acid strength of the organic acid used (concentration of the organic acid aqueous solution), but 2 parts by weight of water is added to 1 part by weight of the treated zeolite composition. When p
It is preferable to adjust H so as to be in the range of 5.5 to 6.5.

As the organic acid, lower fatty acids such as acetic acid, propionic acid and valeric acid, or a mixture thereof or wood vinegar is used. The use of wood vinegar is preferable because it has a bactericidal effect at the same time as the organic acid treatment.

[0010] treatment with amino acids, can be carried out by a conventional method, for example, with an aqueous solution of amino acids, it can be carried out similarly to the above-mentioned organic acid treatment. Further, the amino acid treatment may be performed simultaneously with the organic acid treatment. The amount of amino acid added is preferably such that it accounts for 0.001 to 0.1% by weight in the soil conditioner. Also, other plant nutrients such as phosphoric acid, nitrogen, and potassium can be added simultaneously with the addition of the amino acid or separately.

[0011] treatment with acid can be carried out using an amino acid-containing fertilizers. Various fertilizers containing amino acids are commercially available, and one example thereof is Nissan Urea Complex Liquid Fertilizer No. 1066 (manufactured by Kaisai Nissan Chemical).
Kumiai urea compound fertilizer No. 1 (made by Coop Chemical), Sumitomo urea compound liquid fertilizer No. 1, 3 (all made by Sumitomo Chemical Co., Ltd.),
Taki urea mixed liquid fertilizer No. 12 (iron added), Kumiai urea mixed liquid fertilizer special No. 2 (manufactured by Mitsui Toatsu Fertilizer), urea mixed liquid manure deca green (Cu, Zn added) (Yamamoto Pesticides), Sunpro (made by Sunpro) )and so on.

The soil improving material of the present invention can be improved by spraying an appropriate amount on the surface of the soil or mixing it into the soil in consideration of the condition of the soil. As an example, 0.1 to 1K per 1 m ² immediately before spraying pesticides.
By evenly spraying g on the surface of the lawn, or by mixing 50 to 100 kg per 1 m ³ of turf soil directly under the lawn, the pesticide is prevented from flowing out, and the duration of the medicinal effect of the pesticide is prolonged, It is possible to improve the physical and chemical properties of lawn soil.

[0013]

When compared with, by treating the zeolite in combination with an organic acid and an amino acid, these act additively to dramatically improve the growth situation of turf, and in the present invention product to soil It can be seen that the growth condition of grass is improved to such an extent that the surface is almost completely covered with grass at a mixing amount of about 90 kg / m ³ . On the other hand, when a soil conditioner obtained by treating zeolite with an organic acid or an amino acid alone is used, 90 kg
Even when it is mixed with soil in an amount of / m ³ , the improvement effect is small with the surface coverage of grass being about 75%. Further, comparing FIG. 4 (invention product) with FIG. 6, FIG. 8 and FIG. 10, when zeolite is treated with an organic acid and an amino acid in combination, these act in a complementary manner. The growth situation of grass is dramatically improved, and in the present invention, the amount mixed with soil is 90 kg / m.
^{In 3} it can be seen that the mortality rate of turf due to pest damage is reduced to about 1%. On the other hand, when the zeolite was treated with only the organic acid, almost no improvement effect was seen as compared with the case of only the zeolite, and when the zeolite was treated with only the amino acid, rather the pest control was performed at a high mortality level. The effect of action is saturated, and the amount mixed into soil is 90 kg /
At m ^3, the mortality is higher than that of zeolite alone.
