Figure 4. Collecting soil from the whole rhizosphere region of
large established trees is impractical. Collecting rhizosphere
communities by sampling 1 m out from the base of trees using a soil
corer is a viable methodologic approach and is a more targeted way of
rewilding microbial communities than current soil inoculation studies.
Previous research has demonstrated that rhizosphere signatures can be
detected using this approach for microbe communities from rainforest
plant species despite the complex overlapping root networks (Woodet al. , 2020).
