COMPETING SERIES:
These are the
Broadaxe,
Eastpoint, McKissack,
Mullet,
Pelican Reef,
Sandbank, and
Thalinectes series.
Broadaxe soils--Formed on submerged wave-cut platforms and contain buried spodic horizons.
Eastpoint soils--Formed on submerged wave-cut platforms and can have oxidized pHs below 7.4.
McKissack soils--Formed on brackish estuarine tidal streams from eroded spodic soil materials, commonly have hues of 7.5YR and chromas greater than 3, and organic stains between sand grains.
Mullet soils--Formed on washover-fan flats and have higher organic carbon densities in the surface.
Pelican Reef soils--Formed on relict flood-tidal deltas and have higher organic carbon densities in the surface.
Sandbank soils--Formed on estuarine tidal stream deltas where the major rivers meet the estuary, have higher organic carbon content and allow loamy sand textures
Thalinectes soils--Formed in sandy lagoonal and marine deposits on washover-fans and longshore bars and have higher soil organic carbon densities in the surface.
GEOGRAPHIC SETTING:
Landscape--Bays and Lagoons along the Gulf Coast
Landform--Flood tidal-deltas
Parent material--Sandy lagoonal deposits
Slope--0 to 1 percent
Water depth range--0 to 2 meters (0 to 6 feet) below mean sea level
Water salinity range--20 to 35 parts per thousand

Soil temperature range--19 to 27 degrees C (66 to 81 degrees F)
GEOGRAPHICALLY ASSOCIATED SOILS:
These are the
Amtrac,
Apalachicola,
Dregs,
Dry Bar,
Pelican Reef,
Sheepshead, and
Thalinectes soils.
Amtrac soils--Are on high-energy lagoon bottoms and barrier coves and formed in coarse-loamy lagoonal deposits.
Apalachicola soils--Are on bay and lagoon bottoms and formed in fine-loamy lagoonal deposits.
Dregs soils--Are on dredge-deposit shoals and formed in sandy, human transported materials
Dry Bar soils--Are on shoals and reefs and formed in sandy-skeletal lagoonal deposits.
Sheepshead soils--Are in barrier coves and formed in sandy and coarse-loamy lagoonal deposits.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage class--Subaqueous
Saturated hydraulic conductivity--High to very high
Soil moisture regime--Peraquic
Soil is continuously inundated by brackish or salt water.
USE AND VEGETATION:
Major uses--These soils are used for recreational fishing and are dredged for commercial passage. Lutz soils can be intertidal depending on depositional patterns.
Typical vegetation--Vegetation is largely absent on Lutz soils. Where lower wave-energy persists, limited stands of shoal grass (Halodule wrightii) may establish.
DISTRIBUTION AND EXTENT:
General area--Bays and Lagoons on the Gulf Coast of Florida
Land Resource Region(s)--T - Atlantic and Gulf Coast Lowland Forest and Crop Region
MLRA(s)--152A
Extent--Small
