The effect of some carbon substrates on denitrification rates and carbon utilization in soil

摘要

Soil was amended with a variety of carbon sources, including four soluble compounds (glucose, sucrose, glycerol and mannitol) and two plant residues (straw and alfalfa).. Potential denitrification rates, measured both as N2O accumulation and NO3−disappearance, were compared, and the predicted values of available C, measured as CO2production and water-extractable C, were assesse
