Purpose Forests play a critical role in terrestrial ecosystem carbon cycling and the mitigation
of global climate change. Intensive forest management and global climate change have had …

The stability and decomposition of biochar are fundamental to understand its persistence in
soil, its contribution to carbon (C) sequestration, and thus its role in the global C cycle. Our …

Soils and sediments worldwide contain appreciable amounts of thermally altered organic
matter (chars). Chars contain electroactive quinoid functional groups and polycondensed …

Pyrogenic carbon (PyC; includes soot, char, black carbon, and biochar) is produced by the
incomplete combustion of organic matter accompanying biomass burning and fossil fuel …

Landscape fires burn 3–5 million km2 of the Earth's surface annually. They emit 2.2 Pg of
carbon per year to the atmosphere, but also convert a significant fraction of the burned …

The production of pyrogenic carbon (PyC; a continuum of organic carbon (C) ranging from
partially charred biomass and charcoal to soot) is a widely acknowledged C sink, with the …

Use of a single factor for converting soil organic carbon to soil organic matter is challenged.
The basis for this challenge arises from four sources: the original papers published in the …

Global biomass burning generates 40 million to 250 million tons of charcoal every year, part
of which is preserved for millennia in soils and sediments. We have quantified dissolution …

Contemporary soil science and conservation methods of effective forestry Forests and the
soils that serve as their foundation cover almost a third of the world's land area. Soils …

Soil carbon (C) is a dynamic and integral part of the global C cycle. It has been a source of
atmospheric carbon dioxide (CO2) since the dawn of settled agriculture, depleting more than …
