Abstract A method for the semiquantitative estimation of charcoal (char) in soils is reported. The technique, performed on the 90% of soil char in the <53 μm fraction. Because of the assumptions used, estimates of char by this approach must be considered to be semiquantitative, but are conservative and provide estimates of the minimum char content of a soil.
