The stability and turnover of soil organic matter (SOM) are a very important but poorly understood part of carbon (C) cycling. Conversion of C3 grassland to the C4 energy crop Miscanthus provides an ideal opportunity to quantify medium‐term SOM dynamics without disturbance (e.g., plowing), due to the natural shift in the δ13C signature of soil C. For the first time, we used a repeated 13C natural abundance approach to measure C turnover in a loamy Gleyic Cambisol after 9 and 21 years of… 
Accumulation of C4‐carbon from Miscanthus in organic‐matter‐rich soils
To evaluate the sustainability of biomass plantations, effects on soil organic carbon (SOC) need to be quantified. Miscanthus × giganteus is increasingly used as a bioenergy plant, and it has been
Measured and modelled effect of land‐use change from temperate grassland to Miscanthus on soil carbon stocks after 12 years
Over the longer term, new Miscanthus C4 carbon replaces pre‐existing C3 carbon, though not at a high enough rate to completely offset losses by the end of year 12, and wider implications are considered in the context of life cycle assessments based on the heating value of the dry matter feedstock.
Carbon (δ13C) dynamics in agroecosystems under traditional and minimum tillage systems: a review
Following cultivation, substantial loss of soil organic matter occurs in surface soil layers. No-till is an agronomic practice to reverse or slow the loss of soil organic matter. We reviewed 95
Agroforestry systems: Meta‐analysis of soil carbon stocks, sequestration processes, and future potentials
Agroforestry (AF) has the potential to restore degraded lands, provide a broader range of ecosystem goods and services such as carbon (C) sequestration and high biodiversity, and increase soil
Ecoenzymatic stoichiometry reveals phosphorus addition alleviates microbial nutrient limitation and promotes soil carbon sequestration in agricultural ecosystems
Variation in soil microbial metabolism remains highly uncertain in predicting soil carbon (C) sequestration, and is particularly and poorly understood in agroecosystem with high soil phosphorus (P)
Miscanthus sacchriflorus exhibits sustainable yields and ameliorates soil properties but potassium stocks without any input over a 12‐year period in China
The perennial C4 Miscanthus spp. is used in China for bio‐fuel production and its ecological functions. However, questions arise as to its economic and environmental sustainability in abandoned
Temperature sensitivity of soil organic matter mineralization decreases with long‐term N fertilization: Evidence from four Q10 estimation approaches
Climate warming and anthropogenic nitrogen (N) loads are two major global change components interactively affecting carbon cycling. However, the effects of N forms and amounts on temperature


Soil carbon changes under Miscanthus driven by C4 accumulation and C3 decompostion – toward a default sequestration function
A climate‐dependent VC‐induced SOC sequestration rate is found, as a step toward a default SOC change function for Miscanthus plantations on former croplands in Europe, and a SOC fractionation is conducted to assess qualitative SOC changes and the incorporation of C4 carbon into the soil.
Carbon sequestration under Miscanthus in sandy and loamy soils estimated by natural 13C abundance
Summary Most studies of soil organic-carbon (SOC) dynamics using 13 C natural abundance have been conducted with maize.Here, we present data about the sequestration of C derivedfrom a perennial C 4
Turnover and availability of soil organic carbon under different Mediterranean land‐uses as estimated by 13C natural abundance
Soil organic matter (SOM) is an important factor in ecosystem stability and productivity. This is especially the case for Mediterranean soils suffering from the impact of human degradation as well as
Carbon sequestration under Miscanthus: a study of 13C distribution in soil aggregates
The growing of bioenergy crops has been widely suggested as a key strategy in mitigating anthropogenic CO2 emissions. However, the full mitigation potential of these crops cannot be assessed without
Land use change from C3 grassland to C4 Miscanthus: effects on soil carbon content and estimated mitigation benefit after six years
To date, most Miscanthus trials and commercial fields have been planted on arable land. Energy crops will need to be grown more on lower grade lands unsuitable for arable crops. Grasslands represent

Abstract. Independent of its chemical structure carbon (C) persists in soil for several decades, controlled by stabilization and recycling. To disentangle the importance of the two factors on the
