PROBLEM TO BE SOLVED: To provide raising seedling culture soil which is obtained by a method for producing raising seedling culture soil, related to a method for promoting fermentation of organic polluted sludge, comprising firing carbide maximally retaining the condition of porous raw material including diatom earth, crushed chaff and crushed wood to utilize their properties of having a large specific surface area so as to sufficiently perform function such as water holding properties, adsorbing properties, water-permeable properties and air permeable properties, which has function for chlorine removal, bacteria elimination and sterilization, and also in which a process of segmentalization and fractionalization of a large amount of inexpensive raw material is improved by filling the mixture of the raw materials in a bag body for about two weeks.SOLUTION: The raising seedling culture soil includes carbide efficiently performing useful function from the porous diatom earth, the crushed chaff and the crushed wood. The raising seedling culture soil has an effect of supplying mineral components and an effect of relieving the concentration of fertilizer, and has homogeneous good quality with less unevenness. The method for producing raising seedling culture soil, related to a method for promoting fermentation of organic polluted sludge, comprises filling the mixture in an air-permeable bag body to let the mixture naturally ferment. |
