The charring process is accompanied by drastic chemical alterations of the litler material, which are manifested in the transfer of biologically available structures such as carbohydrates, proteins and lipids into relatively inert aromatic macromolecules. Thus, beside influencing the long-term C-sequestration, the input of charred residues into soils is expected to have a major impact on the quality and quantity of Iheir organic matter but also on the humification processes.
