Nitrogen (N) losses from agroecosystems harm the environment via increased nitrate (NO3-) amounts in water-bodies and nitrous oxide (N2O) emissions to the atmosphere. Bacteria and archaea oxidize ammonium (NH4+) to NO3- under aerobic conditions. Furthermore, under mainly anaerobic conditions, microbial denitrification reduces NO3- to gaseous N forms. The tropical forage grass Brachiaria humidicola (Rendle) Schweick (Bh) has been shown to reduce soil microbial nitrification via root derived substances. Therefore, biological nitrification inhibition (BNI) by Bh might contribute to reduction of N losses from agroecosystems. The present doctoral thesis aimed at assessing the potential of the actual BNI by Bh, as well as the residual BNI effect...
