Abstract
Abstract The purpose of this research is to see the development of soil and management strategy of the boca formation in the Temanggung, Central Java, Indonesia. The boca range in Temanggung are hills located in Danurejo, Central Java, which are part of the old Sumbing mountain formation. This area is thought to be an intrusion area of cracks from the old Sumbing mountain, located at the foot of the mountain between Sumbing and Sindoro mountains. The boca formation is located at 705.9 m above sea level (m asl), in general the Boca formation consists of breccia, andesite, anglomerate and tuff. Vegetation that grows in the boca range includes bamboo and cotton. Soil genesis in the boca range has not yet reached an advanced stage of development characterized by the formation of an argillic horizon. The observed soil shows a diagnostic horizon, the cambic horizon. The soil acidity level (pH 5-6.5), falls into the slightly acidic class, with a texture dominated by geluhan. Based on the data obtained through field survey and laboratory analysis, the soils in the boca range are classified into Inceptisols based on USDA, Cambisols based on PPT and Cambisols based on WRB with ustic regime.
