Addendum 4—Soil Descriptions
Silver River State Park Soil Descriptions
Adamsville sand, 0 to 5 percent slopes (2). - The Adamsville series consists of nearly
level to gently sloping, somewhat poorly drained soils that are sandy to a depth of 80
inches or more. This is a nearly level to gently sloping, somewhat poorly drained soil that
occurs as small and large areas in the flatwoods and along the lower slopes of the sandy
uplands.
In a representative profile, the surface layer is dark gray sand about 6 inches thick. The
underlying material to a depth of 88 inches is sand. The upper 14 inches is gray mottled
with light brownish gray, the next 8 inches is gray mottled with brownish yellow, and the
lower 60 inches is white mottled with light gray.
Anclote-Tomoka association (4). - This mapping unit consists of very poorly drained,
nonacid mineral and organic soils. It occurs as large areas on the flood plain along the
Oklawaha River. It is about 45 percent Anclote soil and 40 percent Tomoka soil but the
composition differs from area to area. The outer rims of delineated areas are dominantly
Anclote soil, and the flooded areas toward the river are dominantly Tomoka soil. Slopes
are less than 2 percent.
In this unit are areas where a 24 to 35 inch, very dark gray sandy surface layer is
underlain to a depth of more than 60 inches by gray or light gray, nonacid sand; areas
where an 8 to 16 inch, black surface layer that is more than 20 percent organic matter is
underlain to a depth of more than 60 inches by sandy material; and many areas of
Okeechobee and Terra Ceia soils.
Apopka sand, 0 to 5 percent slopes (5).- This mapping unit consists of well drained
eolian deposits and/or sandy and loamy marine deposits. It occupies a small area in the
north central portion of the property. The depth to restrictive features is more than 80
inches. The depth to the water table is more than 80 inches, and the capacity of the most
limiting layer to transmit water is rated at moderately high to high. Slopes are 0 to 5
percent. Soil profile consists of sand at 0 to 55 inches and sandy clay loam at 55 to 80
inches. This soil can be found on ridges and dunes of xeric uplands.
Udalfic Arents, 0 to 5 percent slopes (7).- This mapping unit consists well drained of
altered marine deposits. It occupies a large area north of the spring. The depth to
restrictive features is more than 80 inches. The depth to the water table is more than 80
inches, and the capacity of the most limiting layer to transmit water is rated at high to
very high. Slopes are 0 to 5 percent. Soil profile consists of sandy clay loam at 0 to 33
inches and fine sand at 33 to 65 inches.
Bluff sandy clay (19). - The Bluff series consists of nearly level, very poorly drained soils
that formed in thick beds of alkaline loamy marine sediments. Slopes are 0 to 2 percent.

In a representative profile, the surface layer is about 17 inches thick. The upper 6 inches is
black sandy clay, the next 7 inches is black sandy clay loam, and the lower 4 inches is
very dark gray sandy clay. The subsoil is between depths of 17 and 60 inches. The upper
12 inches is dark gray sandy clay and has few medium streaks and pockets of white
calcium carbonate; the next 9 inches is gray sandy clay loam and has common fine streaks
and pockets of white calcium carbonate; and the lower 22 inches is gray sandy clay loam
and has common fine streaks and pockets of white calcium carbonate.
Candler sand, 0 to 5 percent slopes (22). - The Candler series consists of nearly level to
strongly sloping, excessively drained soils that formed in thick beds of sandy marine
deposits. These soils occur as broad areas of the sandy uplands.
In a representative profile, the surface layer is dark gray sand about 5 inches thick. It is
underlain by 62 inches of yellow sand. The next 42 inches is very pale brown sand that is
mottled with white and has thin lamellae of yellowish brown loamy sand. Below this is 6
inches of brownish yellow sandy loam.
Electra sand, 0 to 5 percent slopes (26). - The Electra series consists of nearly level to
gently sloping, somewhat poorly drained sandy soils that formed in thick beds of sandy
and loamy marine sediments. These soils occur in the flatwoods and in the sandy areas of
the upland.
In a representative profile, the surface layer is gray sand about 4 inches thick. Next, in
sequence downward, is 13 inches of light gray sand; 24 inches of white sand streaked
with grayish brown; 4 inches of black, weakly cemented sand that is well coated with
organic matter; 5 inches of dark reddish brown, weakly cemented sand that is mottled
with black and dark brown and is well coated with organic matter; 4 inches of brown
sand; and 6 inches of mottled light brownish gray and pale brown sandy clay loam.
Below the sandy clay loam is 12 inches of mottled gray light sandy clay.
Placid sand (58). - The Placid series consists of nearly level, very poorly drained sandy
soils that formed in thick beds of sandy marine deposits. These soils are in small
depressions and along poorly defined drainageways of the flatwoods and in shallow
depressions on sandy ridges. Slopes are 0 to 2 percent.
Samsula-Martel complex, depressional (64).- This series consists of very poorly drained
herbaceous organic materials over sandy and loamy marine deposits. These soils exist in
depressions on marine terraces. Slopes are 0 to 2 percent, and the depth to restrictive
features is more than 80 inches. The depth to the water table is about 0 inches. The
frequency of flooding is none, but the frequency of ponding is high. The soil profile is
muck at 0 to 31 inches, sand at 31 to 49 inches, and sandy clay loam at 49 to 60 inches.

Tavares sand, 0 to 5 percent slopes (69). - The Tavares series consists of nearly level to
gently sloping, moderately well drained soils that formed in thick beds of sandy marine
deposits. These soils occur in the broad sandy flatwoods and along lower slopes of the
sandy uplands.
In a representative profile the surface layer is sand about 6 inches thick. The upper 3
inches is dark gray, and the lower 3 inches is gray. The underlying material to a depth of
85 inches is sand. It is pale brown between depths of 6 and 33 inches, pale brown mottled
with yellowish red between 33 and 42 inches, very pale brown mottled with yellowish
red and light gray between 42 and 53 inches, light gray mottled with very pale brown and
yellowish red between 53 and 63 inches, white mottled with yellowish brown between 63
and 67 inches, and white mottled with gray between 67 and 85 inches.
