A typical landscape of the Pomona soil series (Ultic Alaquods). The Ponoma series consists of very deep, poorly and very poorly drained soils that formed in sandy and loamy marine sediments. Pomona soils are on flats and flatwoods on marine terraces. Slopes range from 0 to 2 percent.
Surface runoff is negligible to very low. Depth to seasonal high water table is 0 to 30 centimeters (0 to 12 inches) of the surface for about 3 months during most years, and 25 to 102 centimeters (10 to 40 inches) most of the rest of the year. Ponding: 0 to 61 centimeters (0 to 24 inches) in depressional areas for 4 to 6 months.
Under natural conditions Pomona soils are used for water quality and wildlife habitat. Cultivated areas are used for truck crops and tame pasture.Potential native vegetation consists of slash pine, longleaf pine, and south Florida slash pine with an understory of sawpalmetto, waxmyrtle, gallberry, creeping bluestem, chalky bluestem, indiangrass, and pineland threeawn.
These soils are of moderate extent, primarily in Florida.
