PROBLEM TO BE SOLVED: To provide a composition capable of inexpensively and efficiently decomposing organic compounds polluting soil into harmless substances, and to provide a decomposing method. SOLUTION: The organic compounds in the soil containing iron compounds are efficiently decomposed by using the composition having an organic compound decomposition property which comprises reducing agents such as alkali metal sulfites and water. The composition containing the reducing agents of equal moles or more to that of the iron compounds under the condition existing the iron compounds of equal moles or more to that of the organic compounds in the soil. The iron compound is preferably a ferrous compound. COPYRIGHT: (C)2007,JPO&INPIT
