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 which can be cultivated without pesticides without using any chemical fertilizer.

[0002]

2. Description of the Related Art A large amount of sludge settled on the bottom of a lake not only causes water pollution but also causes pollution at the place when it is disposed on the ground. It is becoming a big problem today. However, on the other hand, it is also known that this sludge contains abundant nitrogen and phosphoric acid, which are indispensable for the growth of plants. Therefore, if such sludge can be effectively used as a resource useful for plant growth, the two purposes of lake purification and resource reuse can be achieved at the same time. Development is required.

On the other hand, recently, especially in golf courses,
The problems such as the residents' movement to expel the chemical fertilizer, the caddy and the course keeper on the golf course complaining the inflammation of the skin due to the heavy use of the chemical fertilizer are being closely watched, and they are used during cultivation. It has also been pointed out that there are problems caused by entering the human body with pesticides attached. For this reason, it is now indispensable to use pollution-free soil conditioners.

[0004]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems in the prior art and makes effective use of sludge, so that pesticide-free cultivation can be performed without using any chemical fertilizer. An object is to provide a soil improving material.

[0005]

Means for Solving the Problems The soil improving material of the present invention comprises:
It is characterized in that it contains wood dust coal, organic earth and fermented cow dung, and the weight ratio of the wood dust coal is 5 to 30% by weight. First, each component contained in the soil improving material of the present invention will be described.

[0006] In the soil improving material of the present invention, the woody pulverized coal contained as the first component is obtained by processing charcoal into a powder form, and is a lump of powdered carbon. Such wood pulverized coal enhances the air permeability and water retention of the soil,
It has the function of supplying sufficient oxygen and making the soil into an aggregate structure to increase the heat retention. In addition, it also has a great effect on the development of fine roots and root hairs, has an effect of increasing resistance to pests and diseases, reducing rooted quality and yield, and overcoming continuous crop failure.

Next, the organic earth (organic sludge) contained as the second component contains not only a large amount of silicon, iron and calcium, which are apt to be lacking in general upland fields and paddy fields, but also
It also contains a large amount of the three major elements of nitrogen, phosphoric acid, and potassium, which are essential for plant formation, and can use the lake sediment (sludge) and sewage sludge. Particularly, sewage sludge baked at a temperature of about 800 ° C. is preferable because it contains a large amount of silicon, iron, and calcium.

Further, the fermented cow dung contained as the third component has an effect of quickly adapting to other components and fermenting the soil as compared with dry cow dung, which causes a great difference in the growth of agricultural products. .. This fermented cow dung is about 80-90
Obtained by complete fermentation at ° C.

Regarding the content ratios of these three components, the effect does not change even if the organic earth and the fermented cow dung are slightly increased or decreased, but since the wood pulverized coal has strong alkalinity (pH around 8), It is necessary to set the content to be 5 to 30% by weight of the entire soil conditioner. In the soil improving material of the present invention, since the content ratio of wood pulverized coal is within the above range, it can be used for grass, agricultural products, afforestation and the like in general,
It is preferable to appropriately adjust the content ratio of this pulverized coal depending on whether or not the target agricultural crop prefers alkalinity.
In the present invention, as a result of conducting an experiment by changing the content ratio of each component to the entire composition, wood powder coal: organic earth:
The most preferable weight ratio of fermented cow dung is 5 to 20:40 to 6
It is 0:30 to 50.

The soil improving material of the present invention prepared by mixing such wood pulverized coal, organic earth and fermented cow dung has all the soil improving effects of the above-mentioned components, It is excellent in that it enhances the air permeability, water retention and fertilizer retention of the soil and makes good use of other fertilizers. It also accelerates fermentation and enriches the soil, showing excellent soil improvement effects. Therefore, as a result of giving a large amount of chemical fertilizers that have been conventionally used, the soil is thin, and even for greenhouse cultivation and upland where the soil has decreased, by mixing the soil improving material of the present invention, the soil The increase can be facilitated, and the soil improving material of the present invention is particularly suitable for a shallow-floor house or field.

When the soil improving material of the present invention is used in a potted plant or a planter, it is preferable to plant the plant directly in the soil improving material, and when it is used for growing a golf course or turf. Although it is ideal to plant, 30-40 parts by weight of a soil improving agent is generally added to 100 parts by weight of cultivated soil, and the mixture is sufficiently mixed because the amount of use is large. use. Further, even when it is used in farmland, the amount of soil improver added is appropriately adjusted according to the soil condition. Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited thereto.
