Properties of surface crusts of an andisol and their effects on soil-hydrological processes
In this study, changes in the structure and physical properties of the surface crust of an Andisol, especially during the rainfall, were measured by using a rainfall simulator, and effects of surface crust on hydrology and soil erodibility
are discussed. Soil material used was an Andisol (clay loam) taken from an orchard in Yamanashi prefecture of Japan.

This work aims to ascertain the influence of modifications to land use as well as vegetation cover on the steady-state infiltration rate and associated properties of Andisols on the volcanic island of Tenerife (Canary Islands, Spain). Thirty two
the vulnerability of Andisols' soil properties and infiltration to land use modification, while also highlighting the influence of the type of forest cover present.
Runoff and soil erosion under rainfall simulation of andisols from the Ecuadorian Páramo : effect of tillage and burning
In northern Ecuador, soils of high altitude grasslands (páramos) are mainly non-allophanic andisols developed on Holocenic volcanic ash. These soils have a high water retention capacity and are the water tank of central Ecuador. To assess the effect

Water infiltration research was carried out for this study in Andisols at 10 sites. Rainfall simulations were conducted on gentle, moderately-steep and steep slopes (10, 30 and 50%) to determine infiltration, runoff and soil loss as a function
This paper reports a study of humus accumulation and pedogenetic weathering in 3 andisol sequences, one in northern Japan, one in the south and one in central Japan, from which the AA. trace differences in environmental change during the Holocene.
The main purpose of this study is to examine if the soils that are forming on volcanic materials under a dry Mediterranean climate, in Nysros Island, meet the requirements to be classified as Andisols. Soils from 7 sites were sampled and examined
The aim of this research was to study erodibility and runoff-infiltration characteristics of volcanic ash soils of a climate-induced altitudinal Entisols-Inceptisols-Andisols sequence on the slopes of a volcanic peak in the Andes of northern Ecuador
of the soils developing on these volcanic deposits and their classification. Samples were taken from 7 locations of soil on different parent material and of different ages. These soils do not exhibit andic properties and hence cannot be classified as Andisols
sands, and exhibit minimal structural development. Though Eagle Cap soils have developed for the most part on granodiorite, the strong influence of the volcanic ash on pedogenesis leads to a preliminary classification of Andisols, most probably Typic
