Diversity of Soil Physical Properties of Andisols in Toposequence Results from the Eruption of Mount Tangkuban Parahu in Sukawana Tea Plantation

Topography is one of the soil forming factors that affect soil properties and crop productivity. Soil properties that affect crop productivity include soil physical properties. The purpose of this research was to identify the characteristics of soil physical properties including permeability, bulk density, and soil porosity at various slope positions and identify the effect of slope position on soil physical properties. This research was conducted on a toposekuen located in Sukawana Tea Plantation which has an undulating to hilly topography with a slope of 25 - 45%. This research was conducted in May - July 2024. The research method used was comparative descriptive survey method based on direct observation in the field and continued with F-test to see the effect of slope position on soil physical properties with DMRT further test. Soil samples were taken as many as three replicates on each slope position (top, middle slope, lower slope). The results showed that the slope position did not significantly affect the permeability, bulk density, and porosity of the soil.
