Chapter 13. Short-term kinetics of soil microbial respiration - a general parameter across scales

Popis výsledku v původním jazyce

Microbial parameters derived from the short-term Michaelis-Menten type model are tested and applied on the ecosystem study. Soil dried immediately after sampling and stored at 4°C was moistened to 60% water holding capacity and CO2 production was measured (GC) after 24 h (respiration response to water supply, VDS) and between the 5th and 6th day of incubation (basal respiration VBR ). Then glucose was added into the soil and CO2 production was measured 16 to 24 h later (maximum respiration, VMAX). Substrate saturation kinetics of respiration was measured after addition of glucose in 6 different concentrations. Soil heterotrophic respiratory potential was expressed as VDS/VMAX ratio; biologically available C (ACBR ) and potential flush of the biologically available C (ACDS/ACBR ) was estimated using Michaelis-Menten type model.
