Studies have been made on the mixing effect of two kinds of leaf-litter on their decomposition rates, which were measured by the litter bag method in the field and by CO_2 evolution in the laboratory. The addition of hardwood leaves, conifer needles with higher nitrogen, or nitrogen fertilizer hardly accerate the decomposition of conifer needles with lower nitrogen. That is to say, the chemical properties of the added leaves and nitrogen fertilizer may be nothing but to temporarily encourage any biotic activity and promote rapid decomposition of the leaves. However, the mixture of two kinds of leaf-litter in natural condition may show results different from this study, because of the detail change of the circumstance of the A_0 layer.
