Abstract The priming effect (PE) is a key mechanism contributing to the carbon balance of soil ecosystem. Almost 100 years research since its discovery in 1926 have led rich body scientific publications identify drivers and mechanisms involved. A few review articles summarised acquired knowledge; last major one was published 2010. Since then, knowledge on microbial communities involved PE + C sequestration has been considerably renewed. This article reviews current state what extent new...
Abstract Numerical models are crucial to understand and/or predict past and future soil organic carbon dynamics. For those aiming at prediction, validation is a critical step gain confidence in projections. With comprehensive review of ~250 models, we assess how validated depending on their objectives features, discuss predictive can be improved. We find lack independent using observed time series. Conducting such validations should priority improve the model reliability. Approximately 60%...
Direct observations of processes occurring at the mineral-organic interface are increasingly seen as relevant for cycling both natural soil organic matter and contaminants in soils sediments. Advanced analytical tools with capability to visualize characterize submicrometer scale, such Nano Secondary Ion Mass Spectrometry (NanoSIMS) Scanning Transmission X-ray Microscopy (STXM) coupled Near Edge Absorption Fine Structure Spectroscopy (NEXAFS), may be combined locate mineral-associated matter....
Abstract Redesigning agrosystems to include more ecological regulations can help feed a growing human population, preserve soils for future productivity, limit dependency on synthetic fertilizers, and reduce agriculture contribution global changes such as eutrophication warming. However, guidelines redesigning cropping systems from natural make them sustainable remain limited. Synthetizing the knowledge biogeochemical cycles in ecosystems, we outline four that synchronize supply of soluble...
Soils contain the largest carbon (C) reservoir on Earth, but mean residence time (MRT) of soil C is often poorly estimated, despite its importance for assessing efficiency with which soils may serve as a sink atmospheric C. The objective this study was to evaluate how structure simple models dynamics affects MRT determined from isotope-mixing experiments, using data field studies either artificial labelling (FACE) or C3/C4 vegetation change. We first highlighted theoretically...
Summary Understanding the chemical composition of soil organic matter (SOM) requires determination dynamics each class compounds. We measured carbon in neutral carbohydrates by use natural 13 C labelling an experimental wheat and maize sequence extending over 23 years. The isotopic individual monosaccharides was determined hydrolysed particle‐size fractions gas chromatography/combustion/isotope ratio mass spectrometry (GC/C/IRMS) trimethylsilyl (TMS) derivatives. sensitivity terms C/ 12...
Abstract. Physical fractionation is a widely used methodology to study soil organic matter (SOM) dynamics, but concerns have been raised that the available methods do not well describe functional SOM pools. In this we explore whether physical techniques isolate compartments in meaningful and functionally relevant way for investigation of litter-derived nitrogen dynamics at decadal timescale. We so by performing aggregate density (ADF) particle size-density (PSDF) on mineral samples from two...
Abstract. An increase in soil organic carbon stock can contribute to mitigate climate change. International negotiation mechanisms and initiatives call for countries consider land use change management achieve atmospheric CO2 removal through storage terrestrial systems (http://4p1000.org/). As a result, policy makers raised specific operational question the science community: how much at which annual rate additional be stored soils different locations? It has been suggested that ability of...
Abstract The knowledge of tree species dependent turnover soil organic matter (SOM) is limited, yet required to understand the carbon sequestration function forest soil. We combined investigations 13 C and 15 N its relationship elemental stoichiometry along depth gradients in 35-year old monocultural stands Douglas fir ( Pseudotsuga menziesii ), black pine Pinus nigra European beech Fagus sylvatica ) red oak Quercus rubra growing on a uniform post-mining investigated natural abundance...
Abstract. Land planning projects aiming to maximize soil organic carbon (SOC) stocks are increasing in number and scope, often line with the objective reach neutrality by 2050. In response, a rising of studies assesses where additional SOC could be stored over regional global spatial scales. order provide realistic values transferrable beyond scientific community, providing targets accrual should consider timescales needed them, taking into consideration effects C inputs, type, depth on...
Association of organic matter (OM) with mineral phases have been identified as one important process to explain carbon sequestration in soil. Associations include cationic bridging between OM and surfaces, adsorption on surface, co-precipitation minerals. Some recent studies underlined the crucial role poorly crystalline aluminium (Al) iron (Fe) oxides sequestrate carbon. These findings mostly observed so far at a global or continental scale. Moreover, links soil mineralogy geochemistry are...
This study examines the distribution of soil organic carbon and carbon-isotopes with depth among particle size fractions in 2 forest profiles contrasting texture from Cape York Peninsula, Queensland, Australia. The profile on sand has a comparatively low inventory (557 mg/cm2 0–100 cm) exhibits small variations δ13C value. In contrast, clay-rich much larger (1725 large value occur both between different fractions. considerable differences inventories values sites appear to be largely due...
Abstract The understanding of soil organic matter (SOM) dynamics has considerably advanced in recent years. It was previously assumed that most SOM consisted recalcitrant compounds, whereas the emerging view considers as a range polymers continuously processed into smaller molecules by decomposer enzymes. Mainstreaming this new paradigm current models is challenging because their ill-adapted framework. We propose C-STABILITY model to resolve issue. Its innovative framework combines...
