Less attention has been devoted to the understanding of the sequential effect of biological nitrogen fixation (BNF) on microbial ammonia (NH 3 ) oxidation in terrestrial soils. To shed light into this ecologically important relationship, a 15 N 2 -DNA-stable isotope probing (SIP) technique was appli...
