Abstract: Using a free survey method in the field, five minipedons were dug in each of six soil groups based on geology/parent material identified in the study area. Three soil samples were collected from each minipedon at predetermined depths of 0-10, 10-20 and 20-30 cm. Soil Quality Morphological Index (SQMI) was used in the evaluation using texture- weighting class, structure class and rupture-resistance class as assessors. Soil samples were analyzed in the laboratory for organic carbon. Results showed that soils formed over Lower Coal Measures had the highest SQMI, followed by those formed over Alluvium, Shale, Coastal Plain Sands, Upper Coal Measures and False-bedded Sandstone. SQMI was significantly correlated with organic carbon (R = 0.55; R2 = 0.3, n = 90) at 5% level of probability, indicating that either of the two indices can be used to predict soil quality in the study area.
