Family name: Fine-clayey, isohyperthermic, Typic Eutrustox
This soil has a fine texture and isohyperthermic temperature regime 22C It is an Oxisol ox which is an intensely weathered soil predominated by oxides from iron and aluminum due to repeated high precipitation and high temperature ust It is a typical representative of the great group Eutrustox which has 35 base saturation eutr
