POPLE SERIES


The Pople series consists of very deep, poorly drained, slowly permeable soils that formed in sandy and loamy marine deposits influenced by alkaline materials. These soils are on nearly level, flatwoods and low ridges in Peninsular Florida. Slopes range from 0 to 2 percent.

TAXONOMIC CLASS: Loamy, siliceous, active, hyperthermic Arenic Endoaqualfs

TYPICAL PEDON: Pople fine sand--range. (Colors are for moist soil.)

Ap--0 to 8 inches; dark gray (10YR 4/1) fine sand; weak fine granular structure; loose; many fine and medium roots; moderately acid; gradual wavy boundary. (2 to 8 inches thick)

E--8 to 15 inches; light gray (10YR 7/2) fine sand; single grained; loose; slightly acid; gradual wavy boundary. (3 to 15 inches thick)

Bw--15 to 25 inches; light brownish yellow (10YR 6/4) fine sand; single grained; loose; mildly alkaline; abrupt smooth boundary. (0 to 15 inches thick)

Bk--25 to 30 inches; white (10YR 8/2) loamy fine sand; weak fine subangular blocky structure; secondary calcium carbonate in interstices between sand grains and as coatings on the sand grains; non-sticky, non-plastic; strongly effervescent; moderately alkaline; abrupt wavy boundary. (0 to 12 inches thick)

Btkg--30 to 38 inches; light gray (5Y 7/1) fine sandy loam; weak fine subangular blocky structure; secondary calcium carbonate in interstices between sand grains and as coatings on the sand grains; slightly sticky, slightly plastic; strongly effervescent; moderately alkaline; abrupt wavy boundary. (6 to 15 inches thick)

Cg1--38 to 48 inches; light gray (5Y 7/1) fine sand and loamy fine sand; massive; slightly sticky, slightly plastic; moderately alkaline; gradual wavy boundary. (5 to 30 inches thick)

Cg2--48 to 56 inches; gray (N 6/0) loamy sand and fine sand; single grained; loose; moderately alkaline; gradual wavy boundary. (0 to 15 inches thick)

Cg3--56 to 80 inches; light gray (10YR 7/1) fine sand and loamy fine sand mixed with shell fragments; massive; non-sticky, non-plastic; moderately alkaline.

TYPE LOCATION: Glades County, Florida; about 1300 feet west and 900 feet north of the southeast corner of Sec. 16, T. 39 S., R. 33 E.

RANGE IN CHARACTERISTICS: Solum thickness ranges from 35 to 60 inches. Total thickness of the sandy layers, or depth to the Btkg horizon, is 20 to 40 inches. Soil reaction in these sandy layers ranges from moderately acid to moderately alkaline. The remainder of the profile is mildly or moderately alkaline and calcareous. Depth to secondary carbonate accumulations ranges from 10 to 40 inches.

The A horizon has hue of 10YR, value of 2 to 4, and chroma of 1 or 2. Texture is sand or fine sand. Where value is 2 or 3 and chroma of 1, thickness is less than 7 inches.

The E horizon has hue of 10YR, value of 5 to 7, and chroma of 1 or 2. Texture is sand or fine sand.

The Bw horizon, where present, has hue of 10YR, value of 5 or 6, and chroma of 3 to 8. Texture is sand or fine sand.

The Bk horizon, where present, has hue of 10YR, value of 5 to 8, and chroma of 1 or 2. Accumulations of secondary carbonates occur as coatings on sand grains, in interstices between sand grains, and/or as root casts. Texture is loamy sand, loamy fine sand, sandy loam, or fine sandy loam.

The Btkg horizon has hue of 10YR or 5GY, value of 4 to 8, and chroma of 1 or 2, with or without mottles of gray, brown, yellow, or red. Texture is sandy loam, fine sandy loam, or sandy clay loam.

The BC horizon, where present, has hue of 10YR or 5Y, value of 4 to 7, and chroma of 1 or 2. Texture is loamy sand or loamy fine sand.

The Cg horizon has hue of 10YR to 5GY or is, value of 5 to 7, and chroma of 2 or less. Texture is sand, fine sand, loamy sand, loamy fine sand, or a mixture of these. In some pedons, some of the sand grains are pieces of shell.

COMPETING SERIES: These are Boca, Felda, Ft. Green, Isles, Pinellas, and Roemer series in the same family and the Ellzey, Heights, Malabar, Panasoffkee, and Pineda series. Boca soils have limestone bedrock between 20 to 40 inches. Felda, Pinellas, and Roemer soils do not have high chroma Bw horizons, and Felda in addition does not have Bk horizons. Isles soils have limestone bedrock between 40 and 60 inches. Ellzey and Heights are in sandy families. Malabar soils do not have Bk horizons and have sandy surfaces 40 and 60 inches thick. Panasoffkee soils are in a clayey family. Pineda soils are noncalcareous, and they have tongues or intrusions of albic materials into the Bt horizon.

GEOGRAPHIC SETTING: Pople soils occur in flatwoods and low ridges. Mean annual precipitation is about 50 to 60 inches and mean annual temperature is about 70 to 74 degrees F.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Boca, and Malabar soils, and the Ft. Drum and Hallandale series. Ft. Drum soils do not have a Btkg horizon. Hallandale soils are underlain by limestone within 20 inches.

DRAINAGE AND PERMEABILITY: Poorly drained. Runoff is slow. Permeability is moderately slow or slow. The water table is a depth of 6 to 18 inches for 1 to 3 months and depths of 18 to 40 inches for 2 to 6 months in most years.

USE AND VEGETATION: Natural vegetation is principally cabbage palms, liveoaks, longleaf pine, and slash pine with an understory of sawpalmetto, running oak, waxmyrtle, various bluestems, and in places gallberry. Pineland threeawn is the most common native grass. Principal use is for rangeland with lesser acreage planted to citrus, tame pasture grasses, and vegetables.

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