Photo: Soil sampling at 1,341 sites was conducted in 3 depth increments: floc/detritus, 0-10 and

10-20 cm soil.

Map shows the hydrologic units and soil sampling locations - Greater Everglades

ecosystem.

The following properties were analyzed in floc, 0-10 and 10-20 cm soil layers:

Bulk density, total phosphorus, inorganic phosphorus, total carbon, total nitrogen,

total calcium, total magnesium, total iron, total aluminum, and loss on ignition.
