有機無機複合土壌改良剤

Abstract

PURPOSE:To obtain the subject soil improver excellent in improvement of soil fertility, property for utilizing coal ash and preservation of the environment by adding an organic matter to the reactional product of coal ash and an aqueous alkali solution and subjecting the mixture to compounding treatment. CONSTITUTION:The objective soil improver is obtained by adding (B) an organic matter such as activated sludge or bark to (A) a reactional product obtained by reacting a mixture of coal ash such as coal clinker ash or coal fly ash and an aqueous alkali solution of sodium hydroxide, etc., and subjecting the mixture to compounding treatment. Furthermore, in this soil improver, the component A is preferably a reactional product obtained by mixing and reacting a mixture obtained by adding a silicic acid-enriched material such as diatomite or sodium silicate and an aluminum-enriched material such as aluminum chloride to the above coal ash with the aqueous alkali solution.
