PURPOSE:To prepare the subject activating agent normalizing the ecosystem of soil, having a nutrient-supplying ability and a root growth-stimulating ability, and useful for tobacco, vegetables, etc., by mixing the fine powder of a specific clay raw material with the powder of zeolite, etc., kneading the mixture with a mixture aqueous solution containing the extract of green alga, etc., and subsequently molding the kneaded product into granules. CONSTITUTION:The fine powder of a clay raw material containing halloysite and montmorillonite as clay minerals in relatively large amounts is homogeneously mixed with the powder of zeolite and a solidification-acceleration agent in suitable amounts corresponding to the natures of the soil and, if necessary, further with the fine powder of magnetic iron oxide. While being sprayed with the aqueous solution of a mixture containing the extract of green algae and an active green algae, the mixture is rotated, kneaded and granulated with a flat type granulator to prepare, the objective activating agent comprising the granules having a final water content of approximately 55%. |
