PURPOSE:To provide a soil conditioner which enables the effective utilization of industrial wastes and suppresses the decomposition of organic materials in soil to keep the ratio of bacteria/mold in soil to a high level, by adding specific amounts of gypsum and a basic alkaline earth metal compound to yeast cultivation waste liquid. CONSTITUTION:The objective soil conditioner is prepared by mixing homogeneously (A) 100pts.wt. of gypsum, (B) 10-400 parts of dried yeast cultivation waste which is an industrial waste, and (C) 1-50 parts of a basic alkaline earth metal compound (e.g. carbonate, hydroxide, etc. of calcium, magnesium, etc.). |
