Abstract

The physical characteristics of the surface soil are the crucial soil characteristics related to landslides. They can cause landslides and change due to landslides. The physical characteristics of the surface soil in agricultural land play an important role in providing nutrients and as a medium for plant growth. Landslide activities and slope position can change soil characteristics significantly. Studies on the physical characteristics of surface soil in landslide deposition areas have been studied previously, however most of those studies are not discussed yet in regarding with relation of this landslide deposition and agricultural land. The purpose of this study is to characterize and examine the variation of physical characteristics of the surface soil in landslide deposition areas among different landslide activities and slope positions.

The method used in this study was purposive sampling based on landslide activities (active, inactive) and slope position (upper-, middle-, and lower slope). Soil samples were taken on the landslide deposits with a depth of 0-30 cm. Soil samples were 11 variations.

The results showed that the physical characteristics of surface soil based on landslide activities or slope position were fine texture or clay; particle density, bulk density, and porosity were uniform; high atterberg numbers; slightly slow permeability; and low c-organic as well as organic matter content. Variation of the physical characteristics of surface soil showed high values on active landslides and lower slopes. The most influenced soil property due to landslide activities and slope position was soil permeability.
