Gulf Coast Flatwoods, Hammock & Tidal Marsh Peat

Dominant Soil Order: Spodosols / Entisols / Histosols
Parent Material: Quaternary Marine and Fluvial Sand, Organic Muck in Tidal Marshes, and Limestone Hammock Residuum

The Gulf coast from Pasco to Wakulla is flatwoods, tidal marsh, and limestone hammock. SSURGO mapping shows Blanton, Leon, and Meadowbrook on the flatwoods and Dorovan muck in the tidal marshes. Flatwoods sands are wet for much of the year, so trenches fill with water and wet sands rut under equipment. Tidal marsh peat has very low bearing strength and compresses under load. Hammock sites with limestone close to the surface have rock in the trench lines, and sinkholes can open over shallow limestone. Shallow water tables hold surface water on the flatwoods after rain. Muck in the tidal marshes is organic and soft when wet. Sand on the flatwoods is loose and caves when wet. Tidal marsh peat and muck compress under wheel loads. Shallow limestone in hammocks is hard to dig, which slows trench lines.
