The Myakka series consists of deep and very deep, poorly to very poorly drained soils formed in sandy marine deposits. These soils are on flatwoods, high tidal areas, flood plains, depressions, and gently sloping to sloping barrier islands. They have rapid permeability in the A horizon and moderate or moderately rapid permeability in the Bh horizon. Slopes range from 0 to 8 percent. Solum thickness is more than 30 inches.
Reaction commonly ranges from extremely acid to slightly acid.
In tidal, limestone substratum, and shelly substratum phases reaction ranges up to moderately alkaline. Texture is sand, fine sand, mucky sand, or mucky fine sand. Some pedons have a layer of muck less than 3 inches thick on the surface. In some pedons, this horizon has gray, yellow, and brown mottles. Texture is sand or fine sand.
