Abstract

Western part of the East Jawa Southern Mountains, which is distributed from Parangtritis, Yogyakarta to Pacitan Bay is the Gunung-Sewu Hills. The carbonate rocks on the Baron-Wonosari transect has some litofacies, and the soils overlying the rocks show some color varieties. Topography of Baron-Wonosari transect can be divided into two areas: southern part (Baron-Mulo) and northern part (Mulo-Wonosari). The southern part is a hilly land, whereas the northern part is a lowland plain. Soils on the southern part are dominated by red soils group, whereas on the northern part dominated by black soils group. The phenomenon is very interesting to be studied. The aim of research was to study relationship of soil colour with topography and pores of underlying carbonate rocks. Methods consist of landform especially topography observation, and soil colour by Munsell Soil Colour Chart, whereas laboratory analysis namely micro porosity and geochemical of carbonate rock. The results showed that micro pores of rocks have no effect to the soil colour formation. However, secondary pores (macro and mega) be suggested influent on red soil formation. Concentration of iron (Fe) and mangan (Mn) elements of carbonate rock have no effect on the formation of soil colour. Topography and rock secondary porosity be estimated have a role as controlling factors on the formation of soil colour by leaching process mechanism. An area, which has a high leaching capacity tend to be found much of red soils, whereas an area which has a low leaching capacity will be formed black soils.

Abstract

The variation of soil color that developed on carbonate rocks which are generally white, very interesting to be studied. The aim of the study is to examine the formation of two pedons of black soil and red soil by hue 10 YR and hue 5 to 2.5 YR which successively developed on marly limestones and calcarenite. Analysis of mineral properties consist of the total minerals of sand fraction, clay fraction and rock powders. Soil chemical properties include: pH, organic C, exchangeable cations and cation exchange capacity, CaCO3, the amorphous-crystalline of Fe and Mn, the total of Fe and Mn, the analysis of physical properties is the texture of seven fractions. The results showed that the development of the red soil is much more developed than black soil that shown by intensively decalcification process of red soil that impact on the low of pH, base saturation and cation exchange capacity, whereas the development of black soil is inhibited. The formation of black soil is more inherited of clay bearing marly limestone after carbonate dissolution, whereas the red soil development through rubification and illuviation.
