Soil Carbon Modelling in Salix Biomass Plantations: Variety Determines Carbon Sequestration and Climate Impacts
biomass production life cycle assessment climate impact soil organic carbon Salix willow short rotation coppice genotypic difference
2023/12/8
Short-rotation coppice (SRC) Salix plantations have the potential to provide fast-growing biomass feedstock with significant soil and climate mitigation benefits. Salix varieties exhibit significant v...
Contribution of Arbuscular Mycorrhizal Fungal Communities to Soil Carbon Accumulation during the Development of Cunninghamia lanceolata Plantations
stand age arbuscular mycorrhizal fungal community glomalin-related soil protein soil C sequestration
2023/11/22
Arbuscular mycorrhizal (AM) fungi can establish mutual association with most land plants, and impact a series of important ecological processes, including plant productivity, ecological succession and...
Root functional traits mediate rhizosphere soil carbon stability in a subtropical forest（图）
Root functional traits subtropical forest
2023/6/2
Plants can be classified as either resource-acquisitive or resource-conservative strategies based on their root traits. Compared with conservative trees, acquisitive trees produce larger amounts of re...
Detection of the effects of management and physical factors on forest soil carbon stock variability in semiarid conditions using parametric and nonparametric methods
soil organic carbon CART modelling, neural networks
2015/11/26
Forest soils in western parts of Iran are being degraded by inappropriate management. The soil organic carbon (SOC) stock was dominantly affected by this type of degradation. On the other hand, SOC is...
SOIL CARBON STOCKS UNDER PASTURES IN THE BRAZILIAN CERRADO REGION THEIR ASSESSMENT BY ORBITAL REMOTE SENSING
Climate Agriculture Soil Estimation Landsat Spectral
2015/7/29
The article 3.4 of the Kyoto Protocol acknowledges agriculture soils as a potential sink for soil organic carbon (SOC). To estimate
current and potential SOC on a broad scale for these potential sin...
Impacts of land use change in soil carbon and nitrogen in a Mediterranean agricultural area (Southern Spain)
Agriculture in the Mediterranean region arable land crops olive groves vineyards and soil organic carbon
2015/1/5
The agricultural Mediterranean areas are dedicated to arable crops (AC), but in the last decades, a significant number of AC has led to a land use change (LUC) to olive grove (OG) and vineyards (V). A...
Long residence times of rapidly decomposable soil organic matter: application of a multi-phase, multi-component, and vertically resolved model (BAMS1) to soil carbon dynamics
Long residence times rapidly decomposable soil organic matter multi-phase multi-component vertically resolved model soil carbon dynamics
2014/12/19
Accurate representation of soil organic matter (SOM) dynamics in Earth system models is critical for future climate prediction, yet large uncertainties exist regarding how, and to what extent, the sui...
Response of microbial decomposition to spin-up explains CMIP5 soil carbon range until 2100
microbial decomposition soil carbon
2014/12/19
Soil carbon storage simulated by the Coupled Model Intercomparison Project (CMIP5) models varies 6-fold for the present day. Here, we confirm earlier work showing that this range already exists at the...
Sensitivity analysis and calibration of a soil carbon model (SoilGen2) in two contrasting loess forest soils
Sensitivity analysis calibration soil carbon model two contrasting loess forest soils
2014/12/17
To accurately estimate past terrestrial carbon pools is the key to understanding the global carbon cycle and its relationship with the climate system. SoilGen2 is a useful tool to obtain aspects of so...
Can we model observed soil carbon changes from a dense inventory? A case study over England and Wales using three versions of the ORCHIDEE ecosystem model (AR5, AR5-PRIM and O-CN)
model observed soil carbon changes inventory
2014/12/12
A widespread decrease of the topsoil carbon content was observed over England and Wales during the period
1978–2003 in the National Soil Inventory (NSI), amounting
to a carbon loss of 4.44 Tg yrW...
A Paleoclimate Modeling Experiment to Calculate the Soil Carbon Respiration Flux for the Paleocene-Eocene Thermal Maximum
A Paleoclimate Modeling Experiment Calculate the Soil Carbon Respiration Flux the Paleocene-Eocene Thermal Maximum
2014/10/21
The Paleocene-Eocene Thermal Maximum (PETM) (55 million years ago) stands as the largest in a series of extreme warming (hyperthermal) climatic events, which are analogous to the modern day increase i...
Asymmetric Variation in Soil Carbon Emission in Sub-Tropics
Soil Respiration Carbon Emission Bacterial Abundance
2013/2/26
Carbon dioxide emission from soil, known as soil respiration, is one of the major sources of the atmospheric carbon. Understanding the relationship between emission rate and the factors associated wit...
Chronic nitrogen addition causes a reduction in soil carbon dioxide efflux during the high stem-growth period in a tropical montane forest but no response from a tropical lowland forest on a decadal time scale
Chronic nitrogen addition soil carbon dioxide efflux the high stem-growth period a tropical montane forest a tropical lowland forest
2010/1/21
Atmospheric nitrogen (N) deposition is rapidly increasing in tropical regions. We studied the response of soil carbon dioxide (CO2) efflux to long-term experimental N addition (125 kg N ha−1 yr&...
A method to detect soil carbon degradation during soil erosion
