An Introduction to Soil CO₂ Flux

Globally, fluxes of CO2 from soils account for a significant release of carbon to the atmosphere and play an important role in the carbon cycle. Measurement of soil CO2 flux is important in many research areas, including our understanding of global climate change. This webinar is the first in a series from LI-COR Biosciences describing the processes behind soil CO2 flux and measurement techniques. We will introduce the basic concepts of soil CO2 flux, including the effects of pressure, moisture and soil porosity on observed rates.
