“…The greater porosity of the soil in terms of soil physics should be easier to drain water. The results indicate that besides soil porosity, the presence of amorphous materials has improved the soil ability to hold water, and it may give potential for mass movement (Chavarriaga et al 2017). The low soil bulk density also provide support for the soil properties that may hold water (Table 2).…”

A wide and deep soil profile (around 1200 cm) was observed at Ketep Park West Slope of Merbabu volcano Central Java, Indonesia to identify the soil morphology, physical and, chemical and mineralogical properties. Results showed that several soil development processes occurred in each volcanic deposits with different characteristics. Most soil layers met some of andic soil properties criteria such bulk density <0.9 g.cm-3, P retention of >85%, and (Alo + ½ Feo) >2.0%. A thin melanic material showing black color layer was found at the lower part of the soil profile, i.e. in depth from 726 to 798 cm. The dominant material in most soil layers is an allophane. Minerals in the sand fraction were dominated by labradorite and augite, with some layers were hypersthene and green hornblende.

This chapter describes some aspects of the formation of soils derived from volcanic ash, especially soils classified according to the soil taxonomy as Andisols of the mountains of the central mountain range in Colombia, cultivated with pastures for the production of milk, meat, and potatoes. General erosion, caving, mudslides, and landslides reach and cover large urban and rural territories characterized by a high rainfall regime with decadal records of 227 days of rain per year and with total loss of arable, agricultural, and productive layers. This chapter summarizes aspects of the research carried out by the author in these soils, through the description of profiles on 52 pits, field and laboratory analysis of their physical and some chemical properties for the understanding of the moisture storage capacity, and explains the mechanisms that govern their physical properties, composition, and interaction between particles and fluids and, consequently, their intense erodability and high moisture-retention capacity as a detonating mechanism of the processes of erosion and mass removal of secular occurrence in the soils of the region with high population densities causing hundreds of deaths and incalculable economic losses.
