Open AccessDirect and indirect effects of a pH gradient bring insights into the mechanisms driving prokaryotic community structures
pH is frequently reported as the main driver for prokaryotic community structure in soils. However, pH changes are also linked to “spillover effects” on other chemical parameters (e.g., availability of Al, Fe,...
