Surface Soil Type: Silty clay loam to clay
Family name: Fine, loamy to clayey, isohyperthermic, Typic Eutrustox
Loamy to fine textured soils with soil temperature regime of 22C isohyperthermic It is a typical typic representative of great group Eutrustox Eutr means the soil has high base saturation Ox french oxide it is an oxisol an intensely weathered soil predominated by the oxides from iron and aluminum due to repeated high precipitation and high temperature This soil is difficult to manage due to low fertility medium OM low P medium K and low pH It has an ustic ust moisture regime ie pronounced wet and dry season
