Online ConsultationProduct Introduction
Soil respiration is a crucial process in the carbon cycle of soil ecosystems, resulting from the balance between carbon assimilation and decomposition in soil. It is also the primary pathway through which carbon is returned from terrestrial ecosystems to the atmosphere, serving as an indicator of biological activity in soil. Accurate measurement of its release is key to evaluating biological processes within ecosystems.
By monitoring soil respiration and its related parameters, one can estimate the response of root systems and soil microorganisms to climate change. Soil CO₂ flux is influenced by various complex physical and biological processes over time and space. Long-term, continuous, and accurate measurement of soil carbon flux is of great significance for research on carbon flux in terrestrial ecosystems.
Soil respiration measurement instruments can simultaneously display changes in CO₂ concentration, temperature, and humidity inside the respiration chamber, as well as external photosynthetically active radiation intensity. They are widely applied in agricultural ecological research, carbon source and sink studies, global climate change research, land use change studies, ecological restoration research, soil microbial activity assessment, plant ecology research, insect respiration, root respiration, and fruit storage.
