Abstract: The researchers studied soil carbon accumulation and soil microbial biomass under forest and arable land use types in soils of dissimilar lithology origin in Southeastern Nigeria. Soil samples were randomly collected from each land use type among the soil groups. Soil cores were collected for bulk density determination while moist soil samples were used for the estimation of soil microbial biomass. Standard techniques were used in the laboratory analysis of selected parameters. Soil data were statistically analyzed using standard deviation, coeffient of variation and one way Analysis of Variance (ANOVA). Least significant difference at 5% probability was used to identify significance among means. Means values of Soil Organic Carbon (SOC) were highest in soils under forest land use. About 59.3-70.2 ton ha-1 bit when compared with values from arable land use (39.3-46.8 ton ha-1). Stock of soil differed among parent materials. There were significant (p≤0.05) differences in Soil Microbial Biomass Carbon (SMBC) and Soil Microbial Biomass Nitrogen (SMBC) among land use types and soil groups.
