431(Page et al. 1982). Soil organic carbon was determined with the wet digestionmethod. Bulk density was measured on saran-coated clods. Carbon dioxideemissions from soils were determined by the method of Page et al. (1982) andSchinner et al. (1996).Results And DiscussionCarbon SequestrationPotential CO 2emissionsCarbon dioxide emissions for the three locations and surface conditions arepresented in Table 1. On a volumetric basis, potential carbon dioxide emissionsrates varied from 11.05 to 90.89 ton ha -1 yr -1 , depending on land use and studysites. In general, potential carbon dioxide emissions were highest for thecultivated field, intermediate for Imperata cylindrica grassland andChromolaena odorata shrubland, and lowest for forest soils. The greatestdifferences in carbon dioxide emissions occurred between forest and cultivatedfields in Transos. When degraded soils were returned to forest and grass, thecarbon dioxide emissions were lower. The values of carbon dioxide emissionsat all fields were comparable to those measured at other forested sites in othertropical countries (Moraes et al. 1996, Uhl et al. 1988). There is a large potentialfor further carbon dioxide emissions in the soils of cultivated fields and grasslandsbased on differences in measured carbon dioxide at forest, cultivated, andgrassland sites.The rate of decomposition was lowest at the forest sites, intermediateat grassland sites, and highest at cultivated sites. The largest difference - ±52% - was between forests and cultivated fields, which is closely related to theamount of fine litter in each (Table 2). This implies that more stable pools of Cwere accumulated in the reforestation sites compared to the grassland sites.Therefore, these data confirm that reforestation sites are aggrading, and suggestthat there is a substantial potential for decreasing carbon dioxide emissionsthrough increasing forest cover.

Differences in soil organic C concentration by surfaceconditions were generally limited to the surface of 60 cm. The forest sites hadthe greatest soil organic C concentration, ranging from 3.53 - 6.41% in thesurface 20 cm. The cultivated fields had the lowest soil organic carbon, withvalues from 2.12 - 2.98%. The surface soil organic carbon contents of cultivatedfields are typical of those previously reported (Handayani 1991, 1996, 1998,1999, 2000 a). Soil organic carbon declined with the lower age of Imperatacylindrica grasslands in all cases, but it was still generally higher than incultivated fields. Carbon concentrations at grassland sites were intermediateto those reported for the forest and cultivated fields.
