The soil amended with nitrate was incubated for 24 hr by the method previously reported. Effects of organic compounds on NO_3 metabolism and related biochemical reactions in the soil were examined. It was found that the effects widely fluctuated according to both the kind and the amount of added organic compounds. On the basis of changes in the amount of CO_2 and N_2O production with increasing amount of the added organic compounds, various organic compounds were classified into the following 5 groups. 1) Glucose, sucrose, etc.: They were converted quickly and completely into CO_2 and strengthened reduced state of the soil at any level of their addition. Denitrification was enhanced only when their addition was small and was taken over by dissimilatory reduction of NO_3 into NH_3 when their addition became large. 2) Fumarate, lactate, etc.: When their addition was large, their conversion into CO_2 and enhancement of reduced state of the soil were somewhat retarded. Denitrification was not taken over by dissimilatory reduction of NO_3 into NH_3 even when a large amount of these compounds was added to the soil. 3) Xylitol, glycerol, etc.: They were not good substrates for any biochemical reaction. 4) Methanol, leucine, etc.: They were not utilized for any biochemical reaction. 5) Formate, acetate, etc.: They suppressed almost all the biochemical reactions. This was especially remarkable when their addition was large.
