Description

From the summary and conclusions ... 'The low temperature ignition of soil organic matter has been investigated for temperatures ranging from 100 to 500º C. Appreciable losses are found to occur below 100º C.; up to 200º C. heating results essentially in the distillation of volatile constituents, while between this temperature and 300º C. destructive distillation is the major reaction. These reactions are responsible for the removal of 85% of the soil organic matter.By 300ºC. the greater part of the residual organic matter consists of carbonaceous material, and the final reaction is simple ignition of this material. Two hours* heating of the soil at 450º C. or about half an hour at 500º C. are recommended for the removal of 99% of the soil organic matter.'
