Spodosols — acid soils with a subsoil of humus and iron or aluminum

Myakka is mapped on 1.40 million acres in Florida, 89th nationally by area. No series covers more of Florida: it accounts for 4.3% of the state’s mapped soil. It is the only series in the atlas that has rapid water movement. Only four atlas descriptions go deeper than its 216 cm. It is the state soil of Florida.
