%X Organic carbon or organic matter in acidic Tasmanian soils supporting eucalypt plantations was measured by dry combustion using a LECO CHIN-1000 Analyzer (CT), wet oxidation by the Walkley-Black method (CW&amp;B), and loss-on-ignition (LOI at 375&deg;C). CT and CW&amp;B were highly correlated in 119 surface and subsoil samples, and on average, CW&amp;B provided near complete recovery of CT (97%). Although LOI may have released some structural water from the fine-textured soils, and apart from granite-derived soils which need further study, strong regressions were found between LOI and both CW&amp;B and CT which were specific for either basalt or non-basalt soils. Within the non-basalt soils, parent material had little effect on these relationships, although there were large differences in C concentrations of surface soils between soils of different parent materials. The relationships of CW&amp;B and CT to LOI in the basalt soils were significantly different from those in the non-basalt soils.
