Research results indicated that pH significantly affected a range of properties associated with the soil microbial community (Fernández-Calviño et al., 2011) and its ability to process C and N. In particular, increased soil acidity seems to reduce the intrinsic activity of the microbial community probably by a number of direct and indirect routes ...
