Abstract

Arthagiri Social Forestry (HKm) has landscape dominated by hills, and vegetation cover in the form of natural forest in the upstream and shrubs in the downstream, and has climate type D according to Schmidt and Ferguson climate classification. The purpose of this study was to determine the characteristics of the soil at various vegetation cover and altitude at HKm Arthagiri. The method used in this research is descriptive. The determination of sample plots is done by using purposive random sampling. Vegetation cover is divided into 2 classes namely natural forests and shrubs, and each type of vegetation cover is distinguished based on its altitude with the following intervals: 0-150 meters above sea level, 150-300 meters above sea level, and > 300 meters above sea level; whilst the slope of the land is divided into 2 slopes consisting of slope 0- 8% and 9-15%. The results show that the shrub vegetation cover with an altitude of 0-150 meters above sea level and 150-300 meters above sea level have soil texture in the form of clay, dusty clay, and sandy clay; granular soil structure; soil colour of brown and dark reddish-brown; bulk density ranges from 0.77 g.cm-3 - 0.87 g.cm-3; porosity ranges from 56.52% - 66.53%; the depth of the soil layer ranges from 32.7 cm - 100 cm; and soil pH ranges from 3.8 to 5.0. Whereas, in vegetation cover in natural forests with an altitude of 150-300 meters above sea level and > 300 above sea level, have a soil texture of clay and dusty clay; granular soil structure; soil colour of brown and dark reddish-brown; bulk density ranges from 0.68 g.cm-3 - 0.97 g.cm-3; porosity ranges from 53.45% - 66.98%; depth of soil layer ranges from 18.3 cm - 38.3 cm; and soil pH ranges from 3.4 - 5.4.
