PROBLEM TO BE SOLVED: To produce an oxygen-generating material capable of sustaining the generation of the oxygen for a long period without decomposing in a short period and to provide a method for producing the oxygen-generating material. SOLUTION: This oxygen-generating material for soil is produced by compounding 5-95wt.% volume-expanded vermiculite and 95-5wt.% calcium peroxide. The method for producing the oxygen-generating material comprises mixing 10-90wt.% vermiculite raw ore with 90-10wt.% calcium oxide and 5-60wt.% aqueous hydrogen peroxide, heating the resultant mixture at 50-130 deg.C and providing a mixture of the volume-expanded vermiculite with the calcium peroxide. |
