Surface Soil Type: Clay
Family name: Fine, smectitic (ca.), isohyperthermic Vertic Epiaquept
Fine textured soil with moderate amount of clay 18 35 and isohyperthermic temperature regime 22C It is an inceptisol ept ie it is in the incipient development towards mature soil but have not yet fully developed their diagnostic horizons It is saturated with water for repeated periods of time aqu manifested by its grayish color with or without mottles This is a representative of the great group Epiaquepts vertic properties ie it is dominated by clays that shrink and swell producing wide cracks and slickensides due to repeated wetting and drying
