The dependence of soil CO2 fluxes on atmospheric conditions during sub-periods of soil respiration
Soil respiration was measured on rusty soil in a dry forest near Łódź. A two-year series of soil respiration was divided into characteristic sub-periods and relationships between CO2 emission from the soil as well as selected aspectsof climatic conditions were examined. The temperature dependence of CO2 fluxes from the soil is linear from March to June and expotential during the period from June to March. Dividing the year into aphase of growth and a phase of decline and modeling soil respiration for each of these sub-periods separately does not significantly improve the accuracy of the model. The studies have also shown that soil respiration responds with a delay of three days to changes in temperature and relative moisture,but with a 17-day delay to changes in precipitation.
