Abstract

Rock formation as parent material in Pagedongan Village, Banjarnegara influences the properties of the soil formed. The purpose of this research was to identify the morphology and soil classification according to USDA Taxonomy, National Soil Classifications, and World Reference Base for Soils. This study uses a survey method by determining observation points based on a rock formation, namely Peniron Formation, with pyroxene andesite as parent material for observing soil morphology, physical and chemical of soil in the field, then laboratory analysis included soil texture, bulk density, organic C, soil pH H2O and KCl, exchangeable cations K, Ca, Mg, Na, CEC, and base saturation. The results showed that the soil developed in the Peniron Formation with pyroxene andesite as parent material had morphology with diagnostic horizons of umbric epipedon and argillic endopedon. The results showed that the soil classification according to USDA Taxonomy is Typic Palehumults Isohyperthermic, according to National Soil Classifications is Podsolics Ortoxic, and according to World Reference Base for Soils is Loamic Abruptic Alfisols.

Abstract

Soil develops from the rocks of the Waturanda Formation in Lebakwangi Village is from sedimentary tertiary volcanic activity. The purpose of this study was to identify the soil morphology and soil classification in the Waturanda Formation with forest and dry land use according to the Soil Taxonomy 2014, World Reference Base 2015, and National Soil Classification 2016. The soil profile from the topsoil to subsoil under the forest land use was dominated by clay texture (49.04%-56.46%), with particle density 1.20-1.24 g cm-3, bulk density 1.64-1.82 g cm-3, pH (H2O) 4.05-4.68, pH (KCl) 3.42-3.55, organic C 1.47-2.29%, CEC 13.05-19.60 cmol(+) kg-1, and saturation base 24.35%-73.70%. Similarly, the soil profile under the dryland use was dominated by clay texture (37.06%-62.60%), with particle density 1.10-1.20 g cm-3, bulk density 1.58-1.75 g cm-3, pH (H2O) 4.32-4.54, pH (KCl) 3.49-3.65, organic C 0.96-1.66%, CEC 19.95-25.81 cmol(+) kg-1, and saturation base 58.35%-95.43%. Both soil profiles have an udic humidity regime and isohyperthermic soil temperature regime. Soil classification according to Soil Taxonomy, WRB, and NSC for forest land is Humic Eutrudepts, Clayic Haplic Luvisols, and Eutrict Cambisols, while for dryland use is Pachic Hapludolls, Clayic Haplic Luvisols, and Haplic Molisols.
