Abstract Fresh carbon input (above and belowground) contributes to soil sequestration, but also accelerates decomposition of organic matter through biological priming mechanisms. Currently, poor understanding precludes the incorporation these mechanisms into global models used for future projections. Here, we show that can be incorporated based on a simple equation calibrated from incubation verified against independent litter manipulation experiments in land surface model, ORCHIDEE . When ,...
The increase in aridity, mainly by decreases precipitation but also higher temperatures, is likely the main threat to diversity and survival of Mediterranean forests. Changes land use, including abandonment extensive crop activities, mountains remote areas, increases human settlements demand for more resources with resulting fragmentation landscape, hinder establishment appropriate management tools protect forests their provision services biodiversity. Experiments observations indicate that...
Abstract Lateral transport of carbon plays an important role in linking the cycles terrestrial and aquatic ecosystems. There is, however, a lack information on factors controlling one main C sources this lateral flux, i.e., concentration dissolved organic (DOC) soil solution across large spatial scales under different soil, vegetation, climate conditions. We compiled database DOC down to 80 cm analyzed it with aim, first, quantify differences concentrations among ecosystems, zones,...
Abstract. Current land surface models (LSMs) typically represent soils in a very simplistic way, assuming soil organic carbon (SOC) as bulk, and thus impeding correct representation of deep dynamics. Moreover, LSMs generally neglect the production export dissolved (DOC) from to rivers, leading overestimations potential sequestration on land. This common oversimplified processing SOC is partly responsible for large uncertainty predictions response climate change. In this study, we present new...
Abstract. Lateral transfer of carbon (C) from terrestrial ecosystems into the inland water network is an important component global C cycle, which sustains a large aquatic CO2 evasion flux fuelled by decomposition allochthonous inputs. Globally, estimates total exports through terrestrial–aquatic interface range 1.5 to 2.7 Pg yr−1 (Cole et al., 2007; Battin 2009; Tranvik 2009), i.e. order 2–5 % NPP. Earth system models (ESMs) climate ignore these lateral transfers C, and thus likely...
To evaluate the potential of woody bioenergy crops as an alternative energy source, there is need for a more comprehensive understanding their carbon cycling and allocation patterns throughout lifespan. We therefore quantified net ecosystem production (NEP) poplar (Populus) short rotation coppice (SRC) culture in Flanders during its second growing season. Eddy covariance (EC) techniques were applied to obtain annual exchange (NEE) plantation. Further, by applying component-flux-based...
Nitrous oxide emissions are of critical importance for the assumed climate neutrality bio-energy. In this study we report on N2O fluxes from a bio-energy poplar plantation measured with eddy covariance 2 years, after conversion agricultural fields to few months harvesting plantation. A pulse peak was detected land use change and in wake first heavy rainfall. The N2O-N emission during just single week 2.7 kg ha−1 which represented approximately 42% total emitted years measurements. After...
Abstract. Current global models of the carbon (C) cycle consider only vertical gas exchanges between terrestrial or oceanic reservoirs and atmosphere, thus not considering lateral transport from continents to oceans. Therefore, those implicitly all C which is respired atmosphere be stored on land hence overestimate sink capability. A model that represents whole continuum into ocean would provide a better understanding Earth's more reliable historical future projections. first critical step...
Abstract. Dissolved organic carbon (DOC) in surface waters is connected to DOC soil solution through hydrological pathways. Therefore, it expected that long-term dynamics of reflect trends solution. However, a multitude site studies have failed so far establish consistent DOC, whereas increasing concentrations European over the past decades appear be norm, possibly as result recovery from acidification. The objectives this study were therefore understand large number forests (ICP Forests...
Global water erosion strongly affects the terrestrial carbon balance. However, this process is currently ignored by most global land surface models (LSMs) that are used to project responses of storage climate and use changes. One main obstacles implement processes in LSMs high spatial resolution needed accurately represent effect topography on soil sediment delivery rivers. In study, we present an upscaling scheme for including erosion-induced lateral organic (SOC) movements into ORCHIDEE...
Abstract The need for renewable energy sources will lead to a considerable expansion in the planting of dedicated fast‐growing biomass crops across Europe. These are commonly cultivated as short‐rotation coppice ( SRC ), and currently poplar Populus spp.) is most widely planted.

Abstract Soil organic carbon (SOC) is a crucial component of the terrestrial cycle and its turnover time in models key source uncertainty. Studies have highlighted utility δ 13 C measurements for benchmarking SOC global models. We used as tracer within vertically discretized soil module land‐surface model, Organising Carbon Hydrology In Dynamic Ecosystems‐ Organic Matter (ORCHIDEE‐SOM). Our new represents some processes that been hypothesized to lead enrichment with depth follows: 1) Suess...

Abstract. Despite the importance of soil as a large component terrestrial ecosystem, compartments are not well represented in land surface models (LSMs). Indeed, soils current LSMs generally based on very simplified schema that can induce misrepresentation deep dynamics carbon. Here, we present new version Institut Pierre Simon Laplace (IPSL) LSM called ORCHIDEE-SOM (ORganizing Carbon and Hydrology Dynamic EcosystEms-Soil Organic Matter), incorporating 14C into soil. first simulates carbon...
