Plummer Series

The Plummer series consists of very deep, poorly drained soils that formed in sandy and loamy sediments. These soils are in areas of flatwoods. Slopes range from 0 to 2 percent. The soils of the Plummer series are loamy, siliceous, thermic Grossarenic Paleaquults.

Plummer soils are associated with Bivans, Chipley, Dorovan, Mascotte, Osier, Pamlico, Pelham, Pottsburg, Stockade, and Surrency soils. Bivans soils have a Bt horizon at a depth of less than 20 inches. Chipley soils are somewhat poorly drained, do not have a Bt horizon, and are in the slightly higher landscape positions. Dorovan and Pamlico soils are organic. Mascotte soils have a Bt horizon at a depth of 20 to 40 inches. Osier soils do not have a Bt horizon. Pelham soils have a Bt horizon at a depth of 20 to 40 inches. Stockade soils have a Bt horizon within a depth of 20 inches. Surrency soils are very poorly drained. Pottsburg soils have a Bh horizon below a depth of 51 inches and do not have a Bt horizon. Mascotte and Pottsburg soils are in positions similar to those of the Plummer soils. Bivans, Dorovan, Osier, Pamlico, Pelham, Stockade, and Surrency soils are in the slightly lower landscape positions.

Typical pedon of Plummer sand; about 1,800 feet north and 2,900 feet west of the southeast corner of sec. 4, T. 2 N., R. 13 E.

• A—0 to 9 inches; very dark gray (10YR 3/1) sand; weak fine granular structure; very friable; common fine roots; strongly acid; gradual wavy boundary.
• E1—9 to 16 inches; grayish brown (10YR 5/2) sand; weak fine granular structure; very friable; common fine roots; strongly acid; gradual wavy boundary.
• E2—16 to 36 inches; light brownish gray (10YR 6/2) sand; single grained; loose; common fine roots; very strongly acid; clear wavy boundary.
• E3—36 to 52 inches; light gray (10YR 7/2) sand; single grained; loose; few fine roots; strongly acid; abrupt wavy boundary.
• Btg1—52 to 58 inches; light brownish gray (10YR 6/2) sandy loam; weak medium subangular blocky structure; friable; common fine roots; very strongly acid; gradual wavy boundary.
• Btg2—58 to 70 inches; light gray (10YR 7/1) sandy clay loam; common coarse prominent yellowish brown (10YR 5/8) mottles; moderate medium subangular blocky structure; friable; very strongly acid; gradual wavy boundary.
• Btg3—70 to 80 inches; light gray (10YR 7/2) sandy clay loam; common coarse distinct yellowish brown (10YR 5/4) mottles; moderate medium subangular blocky structure; friable; very strongly acid.

The thickness of the solum is 70 inches or more. Reaction ranges from extremely acid to strongly acid throughout.

The A or Ap horizon has hue of 10YR, value of 2 to 4, and chroma of 1 or 2.

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

The Btg horizon has hue of 10YR, value of 5 to 7, and chroma of 1 or 2. It has few to many mottles in shades of brown and yellow. It is sandy loam or sandy clay loam.
