Surface Soil Type: Clay
Family name: fine-clayey, montmorillonitic, isohyperthermic, Inceptic Hapludalf
Soils developed from calcareous shale It is fine textured with less than 60 clay composed mostly of minerals which have shrink and swell capacity montmorillonitic It is an old soil with high base status and an alluvial accumulation of clay in the subsoil horizons from underlying horizons alf Alfisol and exhibits minimum complexity in its horizonation hapl It is found in areas with humid climate that have well distributed rainfall ud udic with 7 months wet and 3 months dry thus have an adequate supply of moisture for crop growth It has a mean annual soil temperature higher than 22C isohyperthermic
