Ameliorating physical and chemical properties of highly weathered soils in the tropics with charcoal – a review
Abstract. Rapid turnover of organic matter leads to a low efficiency of organic fertilizers applied to increase and sequester C in soils of the humid tropics. Charcoal was reported to be responsible
Persistence of soil organic matter as an ecosystem property
This work proposes ways to include understanding of why some SOM persists for millennia whereas other SOM decomposes readily in a new generation of experiments and soil carbon models, thereby improving predictions of the SOM response to global warming.
Nutrient availability and leaching in an archaeological Anthrosol and a Ferralsol of the Central Amazon basin: fertilizer, manure and charcoal amendments
Soil fertility and leaching losses of nutrients were compared between a Fimic Anthrosol and a Xanthic Ferralsol from Central Amazônia. The Anthrosol was a relict soil from pre-Columbian settlements
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
Black Carbon Increases Cation Exchange Capacity in Soils
Black Carbon (BC) may significantly affect nutrient retention and play a key role in a wide range of biogeochemical processes in soils, especially for nutrient cycling. Anthrosols from the Brazilian
Bio-energy in the black
At best, common renewable energy strategies can only offset fossil fuel emissions of CO2 – they cannot reverse climate change. One promising approach to lowering CO2 in the atmosphere while producing
Biochar for Environmental Management: Science and Technology

Sustainable biochar to mitigate global climate change
The maximum sustainable technical potential of biochar to mitigate climate change is estimated, which shows that it has a larger climate-change mitigation potential than combustion of the same sustainably procured biomass for bioenergy, except when fertile soils are amended while coal is the fuel being offset.
