Certainly we are past the time when measurement of the “soil biomass” (referring to the microbial biomass) alone, by whatever method, is considered adequate (Coleman, 1994a). A wide range of soils has been compared for biomass C calculated from biovolume (the measured volume of the cell), from the chloroform fumigation and incubation (CFI) method, and a ratio of biomass C from biovolume to biomass C from CFI (Powlson, 1994) (Table 3.1).

P mineralized from organic P sources appears to be more readily available to mycorrhizal than to non-mycorrhizal plants, but there is no good evidence that mycorrhizal fungi are actually involved in the mineralization process (Jayachandran et al., 1992; Joner and Jakobsen, 1994).

Given the potentially important role of the anthropogenic heat flux in urban climates, the difficulties in quantifying its magnitude and, importantly, that it is driven by energy consumption and urban form – all variables that can be managed and modified to achieve different outcomes – indicate that further research will be important. It also shows how carbon compensation can attract land into forests from less carbon-sequestering land uses such as crop agriculture, thereby increasing carbon storage on the extensive margin.
