MASARYK SERIES


The Masaryk series consists of very deep, moderately well drained, moderate or moderately slowly permeable soils on upland ridges in the Coastal Plain of peninsular Florida. They formed in sandy and loamy marine or eolian deposits. Near the type location, the mean annual temperature is about 73 degrees F., and the mean annual precipitation is about 55 inches. Slopes range from 0 to 8 percent.

TAXONOMIC CLASS: Loamy, siliceous, subactive, hyperthermic Grossarenic Paleudults

TYPICAL PEDON: Masaryk very fine sand on a smooth 2 percent slope, in forest. (Colors are for moist soil unless otherwise stated.)

A--0 to 3 inches; dark gray (10YR 4/1) very fine sand; weak fine granular structure; very friable; many fine and medium roots; very strongly acid; gradual boundary. (3 to 8 inches thick)

E1--3 to 13 inches; pale brown (10YR 6/3) very fine sand; single grained; loose; common medium roots, few large roots; few fragments of charcoal; strongly acid; gradual smooth boundary.

E2--13 to 24 inches; very pale brown (10YR 7/4) very fine sand; single grained; loose; common medium roots, few large roots; few fragments of charcoal; strongly acid; gradual smooth boundary.

E3--24 to 42 inches; very pale brown (10YR 8/2) very fine sand; single grained; loose; common medium roots, few large roots; common uncoated sand grains; strongly acid; diffuse wavy boundary.

E4--42 to 63 inches; very pale brown (10YR 8/2) very fine sand; single grained; loose; few fine roots; many uncoated sand grains; few fine faint brownish yellow (10YR 6/6) masses of iron accumulation; moderately acid; diffuse wavy boundary.

E5--63 to 70 inches; very pale brown (10YR 8/2) very fine sand; single grained; loose; few fine roots; many uncoated sand grains; common medium distinct yellowish brown (10YR 5/6) and brownish yellow (10YR 6/6) masses of iron accumulation; moderately acid; clear smooth boundary. (Combined thickness of the E horizons ranges from 37 to 71 inches)

Bt--70 to 74 inches; 50 percent light brownish gray (10YR 6/2) and 50 percent yellowish brown (10YR 5/6) very fine sandy loam; weak medium subangular blocky structure; friable; few fine roots; sand grains coated and bridged with clay; common medium distinct yellowish red (5YR 4/6) masses of iron accumulation; very strongly acid; clear wavy boundary.

Btg--74 to 90 inches; grayish brown (10YR 5/2) very fine sandy loam; weak medium subangular blocky structure; friable; few fine roots; sand grains are coated and bridged with clay; common medium distinct brownish yellow (10YR 6/6), yellowish brown (10YR 5/6), and yellowish red (5YR 4/6) masses of iron accumulation; very strongly acid.

TYPE LOCATION: Hernando County, Florida; about 1.25 miles west of U.S. Highway 41 and about 1.0 miles north of Powell Road in SE1/4, SW1/4, Sec. 1, T. 23 S., R. 18 E.

RANGE IN CHARACTERISTICS: Solum thickness ranges from 60 to more than 80 inches. Reaction ranges from very strongly acid to moderately acid in the A and E horizons and from very strongly acid to strongly acid in the Bt horizons. Plinthite, where present, is less than 5 percent and is below depths of 60 inches. Depth to redoximorphic features indicative of wetness is more than 40 inches.

The A or Ap horizon has hue of 10YR, value 3 through 5, and chroma 1 through 3. Texture is very fine sand or fine sand.

The upper part of the E horizon has hue of 10YR, value of 6 or 7, and chroma 2 to 8. Fine to medium pockets of uncoated sand grains with hue of 10YR, value 7 or 8, and chroma 1 or 2 range from none to many. Texture is very fine sand or fine sand.

The lower part of the E horizon has hue of hue 10YR, value 6 to 8, and chroma 1 or 2. Iron accumulations in shades of yellow, red, or brown range from none to common. Texture is very fine sand or fine sand.

The Bt horizon has hue 10YR, value 5 through 7, value 3 through 8; or there is no dominant color and it is multicolored in shades of red, yellow, brown, and gray. Redoximorphic features in shades of gray, brown, yellow, or red range from none to many. Texture is very fine sandy loam or sandy clay loam.

The Btg horizon, where present, has hue of 10YR, value 5 through 7, chroma 1 or 2. Masses of iron accumulation in shades of brown, yellow, or red range from few to many. Texture is very fine sandy loam or sandy clay loam.

COMPETING SERIES: These include the Apopka series in the same family. Series in closely related families include the Arredondo, Blanton, Bonifay, Sparr, and Troup series. The well drained Apopka soils are on similar positions and have redder Bt horizons. The well drained Arredondo soils are on similar positions and have more than 5 percent silt plus clay between 10 to 40 inches. Blanton, Bonifay, and Troup soils have mean annual soil temperature less than 72 degrees F. In addition, Bonifay soils have more than 5 percent plinthite within depths of 60 inches. The somewhat poorly drained Sparr soils are on lower positions and have sandy surface and subsurface layers 20 to 40 inches thick.

GEOGRAPHIC SETTING: Masaryk soils are on uplands of the Coastal Plain. Slopes range from 0 to 8 percent. They formed in sandy and loamy marine or eolian deposits. The climate is humid semitropical. The average annual rainfall ranges from 50 to 60 inches and average annual temperature ranges from 72 to 75 degrees F.

GEOGRAPHICALLY ASSOCIATED SOILS: These include the competing Apopka, Arredondo, and Sparr series along with the Candler and Tavares series. Candler and Tavares soils lack Bt horizons within depths of 80 inches. In addition, Candler soils have thin lamella, normally below a depth of 60 inches and lack a water table within depths of 72 inches.

DRAINAGE AND PERMEABILITY: Moderately well drained; rapid permeability in the A and E horizons and moderate or moderately slow in the Bt horizons.

USE AND VEGETATION: Many areas are cleared and used for citrus, watermelons, peanuts, truck crops, and improved pasture. Native vegetation consists dominantly of blue jack oak, turkey oak, post oak, live oak, longleaf pine, and slash pine. The understory vegetation consists of pineland threeawn, creeping bluestem, Florida Paspalum, and other grasses and forbs.

DISTRIBUTION AND EXTENT: Peninsular Florida. The series is of small extent.
