Summary

In six paddy soils from the same volcanic-ash parent material, incubated under submergence, the reduction of ferric iron proceeded linearly against time. A significant negative correlation (r=−0.906, p<0.05) was found between the rate of consumption of ferric iron (reduction) and the ratio of the rate of consumption of organic N compounds to that of ferric iron. Organic N compounds are the main substrate for the iron-reduction metabolism in the soils in which the rate of iron reduction is slow. re]19751028
