Carbon Pools & Fluxes - Globe Carbon Cycle

Witryna10 kwi 2024 · Abstract Natural 13C abundances in different organic matter (OM) pools in the water-stable macro- and free microaggregates of Haplic Chernozem under contrasting land uses (steppe and long-term bare fallow) are described. The 13C fractionation at individual stages in the formation of OM pools is relatively constant … Witryna11 kwi 2024 · “We have great knowledge about carbon in other forms, like dissolved or particulate organic carbon, but not what we call ‘large carbon’ — large wood.” That’s starting to change. ... which is important when modeling how “active” a carbon pool is — that is, how rapidly material is moved around.
