Microbial responses to southward and northward Cambisol soil transplant [PDF]

open access: yesMicrobiologyOpen, 2015
AbstractSoil transplant serves as a proxy to simulate climate changes. Recently, we have shown that southward transplant of black soil and northward transplant of red soil altered soil microbial communities and biogeochemical variables. However, fundamental differences in soil types have prevented direct comparison between southward and northward ...
