Toposequence of soils on the south slope of the Merapi volcano to Baron coast, Yogyakarta.

Abstract

The aim of the research is to know a soil sequence based on the physiographic unit along volcanic slope and limestone area, i.e. south slope of Merapi volcano from Kaliurang to Baron coast, Yogyakarta, Central Java. This research is based an topographic differences as a lithological reflection. Seven sample points are determined in order to discribe and evaluate morphological types of soil profile, physical and chemical properties, and environmental factors. Relative soil potential is analyzed on the basis of the field data. From this research the soil types found in the study area are Regosol, Cambisol, Latosol, Rensina, Grumusol, and Mediterannean.
