Comparison of two soils in Everglades National Park, FL Karen Balentine SWS 5716 Spring 2011
Location of sample sites Soil samples were taken from field sites located on the Harney River, in Everglades National Pak, Fl. The two sites are roughly 300 m apart
Mangrove soil (soil #1) Mangrove forest. Mostly red mangroves, mixed with both black and white mangroves. Used a Russian D-corer (sediment borer) to collect soil samples.

Soil properties and Interpretations • low infiltration rate, low hydraulic conductivitiy • Seasonal high water table depth : <25 cm • Severe limitations for dwellings with basements, septic tank absorption fields and local roads and streets • Site Characteristics • Flood plain • Parent material is mangrove peat (roots and organic matter) • Nearly level slope • Very slow surface runoff • Low erosion potential • Soil Classification • Histosol
Sawgrass soil (soil #2) Sawgrass (Cladium jamaicense) marsh. Located about 300m from site of soil #1. To collect soil cores at these sites, it is a good idea to use a strong intern from Slovakia.
