Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a method for improving soil in agricultural fields such as fields, paddy fields and orchards. More specifically, it applies a treatment substance obtained by impregnating natural zeolite with natural minerals to soil containing harmful substances. The present invention relates to a method for improving agricultural land by neutralizing / reducing detoxified and acidified soil by mixing and adsorbing / decomposing harmful substances.

[0002]

[Prior Art] In the old farmland, natural fertilizers such as human feces and compost were often used as fertilizers, but with the rapid growth after the war, various agricultural chemicals and agricultural chemicals were used to cultivate agricultural products. Has come to the present day. As a result, the ecosystem of farmland has been destroyed and healthy crops cannot be produced.As a result, it is no longer possible to supply crops to maintain the health of people and livestock who eat them. . In addition, excessive nitrogen components, acidifying substances, pesticides, etc. contained in soil flow out by rain and spread widely in the natural world, resulting in adverse effects such as environmental pollution.

In order to solve such problems, a method for improving soil in agricultural land, which was disclosed in Japanese Patent Laid-Open No. 56-70086, was developed thereafter. The soil improvement method for this farmland is a soil improvement method for farmlands, in which harmful substances contained in the soil are neutralized with an improved substance obtained by refining and processing powdery natural shell fossil containing mainly calcium carbonate and carbon dioxide. Therefore, the improvement substance is to be mixed with acidified soil and the soil is neutralized to improve the environment for growing crops.

[0004]

All of the conventional soil improvement methods described above use natural fossil shells as raw materials, and the improvement due to the peculiar components contained in the shell fossils is the revival of the ecosystem. It could not be the method that leads to the fundamental soil improvement. This is because this method detoxifies DDT and BHC contained in soil, organic phosphorus-based pesticides that are highly toxic, heavy metals such as cadmium and mercury, and dioxins such as harmful chemical substances. It was not possible to do so and therefore no improvement was made to promote the growth of healthy soil microorganisms. This is the root cause of the failure to establish healthy agriculture today.

Here, there is a problem to be solved by the present invention. In other words, it is establishing a soil improvement method for adsorbing, decomposing, immobilizing harmful substances and leading to reduction. This is the only way to promote the reproduction of soil microorganisms that co-exist with crops and thus restore the natural ecosystem.

[0006]

The present invention was developed in order to solve the above-mentioned problems, and it includes a natural mineral component in which a substance such as magnesium, iron, sodium, etc. is ionized, and causan, alumina, calcium, etc. The substance is an improved substance mainly composed of an ionized natural zeolite component, and the improved substance is a pesticide such as DDT / BHC and heavy metals such as cadmium / mercury / zinc and dioxin / drine / cyan / PCB. Effectively reduce and neutralize the soil by mixing it with soil containing substances that are harmful to the growth of agricultural products such as chemical substances and harmful to the human body and livestock, and adsorb and decompose the harmful substances as well as immobilize them. The present invention is to provide a soil improvement method for farmland or the like, which is characterized by producing a favorable environment for growing agricultural products and producing healthy agricultural products.
