Description

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 conditioners, 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 zeolitic composition are treated with an organic acid to add an amino acid.

[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 and 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 simultaneously with the treatment with organic acid.

The amino acid addition treatment can be carried out by a conventional method, for example, by using an aqueous solution of the amino acid in the same manner as the above organic acid treatment. Further, the amino acid addition 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.

The amino acid addition treatment can be carried out using an amino acid-containing fertilizer. Various types of fertilizers containing amino acids are commercially available. Examples of such fertilizers include Nissan urea compound liquid fertilizer No. 1066 (Kaisai Nissan Chemical Co., Ltd.), Kumiai urea compound fertilizer No. 1 (Corp Chemical), Sumitomo Urea. Complex liquid fertilizer Nos. 1 and 3 (all manufactured by Sumitomo Chemical Co., Ltd.), Taki urea-containing complex liquid fertilizer No. 12 (addition of iron), Kumiai urea complex liquid fertilizer special No. 2 (manufactured by Mitsui Toatsu fertilizer), urea-containing complex liquid fertilizer deca green (Added Cu, Zn) (made by Yamamoto Pesticides), Sunpro (made by Sunpro), etc.

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]

EFFECTS OF THE INVENTION According to the present invention, a zeolite-based composition is treated with an organic acid and an amino acid is added to form a soil conditioner.
