Myakka soil is the official soil in the state of Florida. It is restricted to the state, where it encompasses the largest acreage. More than 1,500,000 acres (6,100 km2) contain Myakka soils. Its name originates from a Native American pronunciation of "Big Waters".
Myakka soils originate from marine deposits. These soils are a key component of Floridian flatwoods. They are also found in tidal areas, depressions, and barrier islands. Permeability is rapid in the A horizon, and it is "moderate or moderately rapid" in the Bh horizon. Myakka soils' slope ranges from 0 to 8 percent.
