This study investigated the distribution patterns of soil total nitrogen (N), nitrate, ammonium, and stable isotopic ratios(More)
Magnetic biochar is a potential economical anaerobic digestion (AD) additive. To better understand the possible role of magnetic biochar for the improvement of biomethanization performance and the retention of methanogens, magnetic biochar fabricated under different precursor concentrations were introduced into organic fraction of municipal solid waste(More)
