Surface Soil Type: Clay
Family name: Fine isohyperthermic, Aquic Haplustalfs
Fine textured soil with 35 60 clay content and isohyperthermic 22C temperature regime Aquic means the soil is wetter than the typical due to fluctuating groundwater during rainy season where some part of the soil within 1 m deep is saturated for several days but water table recedes during the dry period It is usually mottled which is indicative of somewhat poor internal drainage It is a representative of great group Haplustalfs Hapl the soil has a minimum complexity of horizonation ust it has an ustic moisture regime ie with pronounced wet and dry seasos It is an Alfisol alfs mening there is alluvial accomulation of clay in the subsoil horizons from the underlying horizons The soil fertility is moderate to high medium OM low P medium K with low to high pH This soil is deep to very deep moderately well drained with slow to moderate permeability Crops common in the area maybe grown but is best suited for pasture and forests
