There is currently limited knowledge of which mechanisms are most important for C storage under different soils and
land-use systems, yet such knowledge is crucial for devising systems with efficient C sequestration. This study is therefore
aimed at evaluating the influence of land use type on soil organic carbon (SOC) distribution, SOC protection potentials of soil
aggregate fractions and the relationships between SOC and the soil aggregate stability. In a study conducted at the teaching and
research farm, Obafemi Awolowo University, Ile-Ife, Nigeria, soil samples from 0-15 cm and 15-30 cm depths were collected
under seven different land use types and dry sieved into aggregate size fractions of 1-2, 0.5-1, 0.25-0.5, 0.125-0.25, 0.05-0.125,
and <0.05 mm. The organic matter and total N composition of each of the size fractions were analysed while the water stability
of the macro-aggregate fractions (1-2, 0.5-1 and 0.25-0.5) were determined by wet sieving. The aggregate stability of the size
fractions decreased with increase in aggregate size. The WSA was significantly (P<0.05) positively correlated with SOC for each
aggregate size, but less so at the lower depth indicating that the soils? water stability were mainly mediated by organic C. Soil
tillage and cultivation reduced the soils? SOC.The consistently lower C:N ratio obtained in the fine particle size fractions may
indicate lower decomposition rates, thus suggesting a measure of protection of SOC by the fine sized soil particles
