Micromorphological Characteristics Of Andisols In West Java, Indonesia

Micromorphological characteristics have been studied for six pedons of Andisols developed in volcanic materials in West java, Indonesia. The pedons represent deposits of different volcanoes (Mt.Tangkuban Perahu A and C, Mt. Patuha, Mt. Kendeng, Mt. Papandayan, Mt. Guntur), with different ages (Pleistocene, Holocene) and different types of volcanism (andesitic, basaltic), in three agroclimatic zones (A, B1, B2). Undisturbed soil samples for thin section preparation were taken from every identifiable horizon (49 samples in total). Observations were made with a magnifying lens, binocular stereomicroscope, polarization microscope, and scanning electron microscope. The results demonstrate that the study of micromorphological characteristics is very useful to identify pedogenetic processes in Andisols.
