Abstract: | It has been recently shown that the presence of charcoal might promote humus decomposition in the soil. We investigated the
decomposition rate of charcoal and litters of different biochemical quality mixed together in a soil incubation under controlled
conditions. Despite the large range of organic substrate quality used in this study, we did not find any difference in the
decomposition between the average of two individual substrates decomposing separately and the same substrates mixed together.
We concluded that charcoal does not always promote other organic matter decomposition and that its particular effect might
depend on various factors, for example, soil properties. |
