MORFOLOGI DAN KLASIFIKASI TANAH PADA FORMASI PENIRON BAHAN INDUK ANDESIT PIROKSEN DI DESA PAGEDONGAN, BANJARNEGARA

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