摘要: Metabolic quotients for CO 2 C (qCO 2 C) and microbial-C-loss (qD) were studied on soil microbial communities under long-term monoculture (M) or continuous crop rotations (CR). Under defined laboratory conditions the mean qCO 2 C (unit CO 2 C unit− 1 C mic h− 1) of different microbial biomasses from 17 M systems amounted to 1.097 μg CO 2 qCO 2 CC as compared to 0.645 μg CO 2 C of microbial biomasses from 19 CR systems. The 1.7 times higher CO 2 C release per unit biomass and time of microbial biomasses from M …
