Surface Soil Type: Clay/Sandy loam
Family name: isohyperthermic, Typic Argiaquoll
Soils developed from older alluvial deposits A fine textured soil with less than 65 clay It is dark colored with high organic matter content and high base status oll Mollisol and exhibits accumulation of clay in the subsoil Argi Argillic Alluvial deposit over a once marshland hence partly decayed organic matter is found below the profile This soil is saturated with water for repeated periods aqu of time The mean annual soil temperature is higher than 22C isohyperthermic
