Studies were made on cellulose decomposing powers with Yellow and Ando soils at lwatahara in Shizuoka prefecture. The evolution of CO_2 in cellulose decomposition was found to be stimulated by the additions of nitrogen and phosphorus, but not by potassium. And there was no correlation between the addition of calcium oxide to correct soil acidity and the power of soil to decompose cellulose. From the present experiment, it seemed that fungi will take an active part in cellulose decomposition in these acid soils. Soil inoculation increases the CO_2 evolutions of both nutriented and unnutriented soils. From this result, the strains of cellulose decomposing microorganisms seem to be poor in these soils.
