WebApr 10, 2024 · The soil respiratory quotient (qCO 2) was calculated based on the soil basal respiration rate and soil microbial biomass carbon content using the formula of Anderson and Domsch . The q CO 2 indicates the microbial biomass’s efficiency in using effective carbon for biosynthesis and is considered an important indicator of biological activity and … WebNov 14, 2016 · However, due to a suite of factors beyond temperature that control soil respiration rates (e.g., soil moisture, C substrate quality and quantity, and nutrient availability), the interaction between temperature and respiration remains uncertain (3–5). As such, soil respiration is a major and poorly understood flux in the global C cycle.
