This study was set up to identify the long‐term effect of biochar on soil C sequestration of recent carbon inputs. Arable fields (n = 5) were found in Belgium with charcoal‐enriched black spots (>50 m2; n = 14) dating >150 years ago from historical charcoal production mound kilns. Topsoils from these ‘black spots’ had a higher organic C concentration [3.6 ± 0.9% organic carbon (OC)] than adjacent soils outside these black spots (2.1 ± 0.2% OC). The soils had been cropped with maize for at least… 
Evaluation of the long‐term effect of biochar on properties of temperate agricultural soil at pre‐industrial charcoal kiln sites in Wallonia, Belgium
Research on biochar has increased, but its long-term effect on the fertility of temperate agricultural soil remains unclear. In Wallonia, Belgium, pre-industrial charcoal production affected former
Greater microbial carbon use efficiency and carbon sequestration in soils: Amendment of biochar versus crop straws
While high soil carbon stability had been well known for biochar‐amended soils, how conversion of crop residues into biochar and subsequent biochar amendment (BA) would favor microbial carbon use and
Lower residue decomposition in historically charcoal-enriched soils is related to increased adsorption of organic matter
Abstract Previous field observations have shown increased soil carbon (C) sequestration in charcoal amended soils due to an accumulation of non-charcoal derived soil C. This study was set up to
Partitioning of carbon sources among functional pools to investigate short-term priming effects of biochar in soil: A (13)C study.
Although consistent effects among C sources and biochar materials remains elusive, the outcomes indicate that some biochar products can reduce mineralization and solubilization of other sources of C while promoting their physical protection in soil particles.
Anthropogenic charcoal-rich soils of the XIX century reveal that biochar leads to enhanced fertility and fodder quality of alpine grasslands
Background and aimsSoil incorporation of charcoal (biochar) has been suggested as practice to sequester carbon, improve soil properties and crop yields but most studies have been done in the short
Long-term charcoal-induced changes to soil properties in temperate regions of northern Iran
The long-term performance and benefits of charcoal application on the carbon sequestration and properties of forest soils in temperate or non-tropical regions has not been studied in detail in spite
Long-term presence of charcoal increases maize yield in Belgium due to increased soil water availability
Abstract The short-term benefits of biochar application on crop yield await confirmation with long-term effects when initial liming or nutritional benefits are attenuated. In this study, we
Priming of soil organic carbon induced by sugarcane residues and its biochar control the source of nitrogen for plant uptake: A dual 13C and 15N isotope three-source-partitioning study
Abstract Sugarcane (Saccharum spp.) farming systems globally have largely transitioned away from burning the crop prior to harvest. Harvesting the sugarcane crop ‘green’ results in large volumes of
Organo-mineral associations largely contribute to the stabilization of century-old pyrogenic organic matter in cropland soils
Abstract Understanding the processes underlying carbon (C) stability in soils is of utmost importance in the context of climate change. In this setting, biochar is often studied for its persistence
Aged biochar affects gross nitrogen mineralization and recovery: a 15N study in two contrasting soils
Biochar is a pyrolysed biomass and largely consists of pyrogenic carbon (C), which takes much longer to decompose compared to the biomass it is made from. When applied to soil, it could increase


Black carbon and soil properties at historical charcoal production sites in Germany
Abstract The use of charcoal as a soil amendment is currently of great interest to sequester carbon and improve soil fertility, however, studies of sites where charcoal amendments to the soil have
Carbon Sequestration and Fertility after Centennial Time Scale Incorporation of Charcoal into Soil
It is concluded that 80±21% of the C originally added to the soil via charcoal can still be found there and that charcoal has an overall Mean Residence Time of 650±139 years, thus supporting the view that charcoal incorporation is an effective way to sequester atmospheric CO2.
Abundant and stable char residues in soils: implications for soil fertility and carbon sequestration.
Using quantitative (13)C nuclear magnetic resonance (NMR) spectroscopy, Terra Preta soils consist predominantly of char residues composed of ~6 fused aromatic rings substituted by COO(-) groups that significantly increase the soils' cation-exchange capacity and thus the retention of plant nutrients.
Interactive priming of biochar and labile organic matter mineralization in a smectite-rich soil.
Investigation of the interactive priming effects of biochar-C and LOM-C mineralization in a smectitic clayey soil found that biochar application possesses a considerable merit for long-term soil C-sequestration, and it has a stabilizing effect on LOM in soil.
Bio-char Sequestration in Terrestrial Ecosystems – A Review
The application of bio-char (charcoal or biomass-derived black carbon (C)) to soil is proposed as a novel approach to establish a significant, long-term, sink for atmospheric carbon dioxide in
Positive and negative carbon mineralization priming effects among a variety of biochar-amended soils.
Abstract Pyrogenic carbon (biochar) amendment is increasingly discussed as a method to increase soil fertility while sequestering atmospheric carbon (C). However, both increased and decreased C
A review of biochar and its use and function in soil
Abstract Agricultural activities and soils release greenhouse gases, and additional emissions occur in the conversion of land from other uses. Unlike natural lands, active management offers the
Modelling the long-term response to positive and negative priming of soil organic carbon by black carbon
Observed increases in the mineralization rate of labile organic carbon (LOC) in the presence of black carbon (BC) have led to speculation that corresponding decreases in non-pyrogenic (i.e. non-BC)
