Carbon mineralization of a winery-sludge added to various soils was mo
nitored over 60 days in a laboratory incubation experiment; the rate a
nd extent of decomposition varied greatly among the soils and were fou
nd to be affected by the following soil properties: C/N, cation and an
ion exchange capacities, total microbial activity (F.D.A), Some kineti
c models were evaluated for their suitability in describing the decomp
osition process; the ''Power function'' model best described carbon mi
neralization of winery-sludge organic matter in soil.
