We studied how soil pH (4 - 8) influenced the mineralisation of low molecular weight (LMW) dissolved organic carbon (DOC) compounds, and how this compared with differences in microbial community structure. The mineralisation of LMW DOC compounds was not systematically connected to differences in soil pH, consistent with soil respiration. In contrast, the microbial community composition differed dramatically. This suggests that microbial community composition data will be of limited use in improving the predictive power of soil C models.
