Soil stores over 2500 Pg carbon (C), with the majority of C stored in deep soil layers (> 30
cm). Soil C can be lost to the atmosphere when organic compounds are mineralized to …

Soil moisture is a known environmental factor influencing carbon dioxide (CO 2) emissions
and therefore represents an important variable in predictive models. Establishing …

Soil CO 2 levels reflect CO 2 production and transport in soil and provide valuable
information about soil CO 2 dynamics. However, extracting information from soil CO 2 …

About 10% of the CO2 in the above-ground atmosphere is annually recycled back to the
atmosphere from the soil. Soil respiration (the sum of root and microbial respiration) …

The temperature dependance of soil respiration has most commonly been addressed using
surface flux data, despite the fact that surface flux measurements implicate CO2 transport …

The gradient method is widely used in conjunction with Fick's Law to estimate emissions of
soil CO2. This requires accurate estimation of the soil gas diffusion coefficient (DP) and the …

The relationship between CO2 flow from soil and soil CO2 concentration was investigated at
72 permanent sampling points at two forested post-mining sites in the northwest of the …

Despite the wealth of information available on respiratory fluxes of CO2 from the soil surface,
relatively few studies have examined the depth‐related flux and production of CO2 within …

Wetting induced increases in soil CO 2 efflux (R) from dry soils have been repeatedly
reported, however little is known about the sensitivity of the pulse to temperature. To address …

It has been reported that soils in drylands can absorb CO 2, although the patterns and
mechanisms of such a process remain under debate. To address this, we investigated the …
