More particularly, the present invention relates to a method for preparing a soil conditioner for improving soil strength by pretreating shell and pozzolanic acid soil, The present invention relates to a method for producing a soil conditioner capable of producing a plant culture based on an intermediate mixture obtained during the production of a soil conditioner and a method for producing a plant culture using the intermediate mixture prepared by the method.

As one of the methods for increasing the harvest in agriculture, the work of improving soil properties is being studied steadily. In other words, along with the development of chemical fertilizers, farmers mainly use chemical fertilizer when cultivating crops. The chemical fertilizer has the advantage of increasing the production of crops and artificially controlling the fertilizer component by acting as a rapid effect, but it accelerates the acidification of the soil and weakens the intellectual power, weakening the power to withstand various diseases and causing the use of pesticides.

In order to solve such problems, it is recommended to use an organic fertilizer in which raw materials of plants and animals such as sawdust, fish meal or livestock are mixed. However, there is a problem that preparation and handling of an organic fertilizer containing a natural organic matter are cumbersome, Are not included and are not sufficient to serve as complete plant growth supplements.

In addition, a fertilizer containing a large amount of organic matter may adversely affect the growth of crops when used for a long period of time and also cause a problem of eutrophication of the nearby water quality.

In addition, when the sawdust which is not fully fermented is used, tannin and lignin may remain, which may damage the crops, and organic acids may be formed in the process of corn stalk or fish meal decay, which may damage the roots of the crop.

Therefore, in recent years, many liquid fertilizers using an aqueous solution obtained by processing natural minerals as a fertilizer have been proposed. According to this prior art, Japanese Laid-Open Patent Publication No. 2001-0056874 discloses a liquid fertilizer using germanium and elvan, 2004-0034787 discloses a liquid fertilizer using clay minerals, Patent Publication No. 2005-15195 discloses a liquid fertilizer using germanium, and No. 612641 discloses a liquid fertilizer including granular particles.

The liquid fertilizer using natural minerals as described above contains various minerals and can be useful for promoting the growth of plants.

However, the above-mentioned minerals are insufficient for promoting the growth of plants, the efficiency of extracting minerals from minerals is low, and the ability of plants to absorb them is limited, and thus there is a limit to use as a hydroponic culture solution in addition to fertilizers.
