Abstract
Soils developed on carbonate rock of Baron – Wonosari transect have both chemical character and soil color difference. Red soils developed on karst topography and bioclastic limestone, whereas black soils on bioclastic limestone and marl. Most of red soils have pH, exchangeable Ca, sum of cations, cation exchange capacity, base saturation, totally Ca and Mn which much lower in comparison with black soils. Totally Al and crystalline Fe concentration of red soils are higher than on black soils, but totally Fe concentration of both soils are similar. Soils on karst topography have a unique character that is concentration of Mn on table top and slope much higher than on doline and also of cation exchange capacity and pH, but concentration of totally Fe and Al lower than on doline. Crystallinity of iron oxides on karst topography area restricted by organic carbon, but organic carbon have a role on increasing cation exchange capacity.
