Carbon mineralization of different organic materials added to soil was
monitored over a short time in a laboratory incubation experiment Sev
eral kinetic models were evaluated for their suitability in describing
the decomposition processes. A modified first-order model best descri
bed carbon mineralization for each material. Parameters derived from s
uch a model were tested as indexes for assessing the relationships bet
ween the decomposition in soil of the organic materials and their chem
ical compositions. The term 'initial potential rate of C mineralizatio
n,' especially when normalized to total C added to soil, was found to
be the most effective index for assessing the above-mentioned relation
ship.
