Abstract

A new system was developed for measuring soil CO₂ efflux. The chamber in this system contains a small infrared CO₂ gas analyzer. This system does not need air tubes or pumps for circulating air, so it is expected to offer the advantages of mobility and durability. This system was verified by a comparison with measurements made by using a closed-dynamic-chamber (CDC) system. The spatial variation in the soil CO₂ efflux in a broadleaved deciduous forest was measured using the new system. The soil CO₂ efflux at sampling locations 50-70cm apart varied within a range of 60-150%. This variation was smaller than the variation due to differences in soil characteristic reflected in different moisture conditions, etc.
