Measurement of soil carbon oxidation state and oxidative ratio by C nuclear magnetic resonance
[1] The oxidative ratio (OR) of the net ecosystem carbon balance is the ratio of net O2 and CO2 fluxes resulting from photosynthesis, respiration, decomposition, and other lateral and vertical carbon flows. The OR of the terrestrial biosphere must be well characterized to accurately estimate the terrestrial CO2 sink using atmospheric measurements of changing O2 and CO2 levels. To estimate the O...

متن کاملMicrobe - driven turnover o sets mineral - mediated storage of soil carbon under elevated CO 2
The sensitivity of soil organic carbon (SOC) to changing environmental conditions represents a critical uncertainty in coupledcarboncycle–climatemodels1.Muchof thisuncertainty arises from our limited understanding of the extent to which root–microbe interactions induce SOC losses (through accelerated decomposition or ‘priming’2) or indirectly promote SOC gains (via ‘protection’ through interact...
متن کاملResponses of beech and spruce foliage to elevated carbon dioxide, increased nitrogen deposition and soil type
Although enhanced carbon fixation by forest trees may contribute significantly to mitigating an increase in atmospheric carbon dioxide (CO2), capacities for this vary greatly among different tree species and locations. This study compared reactions in the foliage of a deciduous and a coniferous tree species (important central European trees, beech and spruce) to an elevated supply of CO2 and ev...
متن کاملEcosystem assembly and terrestrial carbon balance under elevated CO(2).
Research aimed at understanding how the global carbon balance will change with elevated CO(2) has largely ignored the responses of individual species and genotypes. Yet, plant traits strongly influence the biogeochemical cycling of carbon. Here, we illustrate how differences in inter- and intraspecific responses to elevated CO(2) affect not only physiology and growth, but also higher order biot...
