Surface Soil Type: Clay/Silty clay loam
Family name: Fine, smectitic, isohyperthermic, Typic Calciaquert
A fine textured soil with high amounts of clay 35 60 dominated by minerals with high shrink and swell capacity smectitic that cause deep wide cracks resulting in rapid drying of the soil and washing of some soil materials into cracks when rains come accounting for relatively low OM content of the surface soil which is very sticky and has low hydraulic conductivity when wet and compact when dry This soil is saturated with water for repeated periods aqu and has a high calcium saturation in its subsoil horizons Calci The mean annual soil temperature is higher than 22C isohyperthermic
