Information is contradictory about the contributions of root-derived C to the C pools available to the root zone and how this readily available C affects the subsequent associated microbial transformations of soil N (107). In a greenhouse experiment that involved growing maize plants and using C natural abundance and isotope "N techniques, 15% of the soil microbial biomass was derived from... [Pg.177]

Protocols for rhizosphere sampling need to be developed. Upon quantifying processes at the rhizosphere level, we may find whether large or small rhizosphere volumes or high or low rates of exudation are plant-specific and how they will benefit plants. This is not clear as yet and is an area for future research. In addition, reliable methods that enable us to distinguish between dormant and active soil microbial biomass could represent the crucial step in order to mechanistically understand C and N flows among plants, soil, and microbes in the rhizosphere. [Pg.186]
