Plummer Series

The Plummer series consists of very deep, poorly drained, moderately permeable soils that formed in sandy and loamy marine sediments. These soils are on flats and in poorly defined drainageways in the coastal lowlands and on the uplands. Slopes range from 0 to 5 percent. These soils are loamy, siliceous, subactive, thermic Grossarenic Paleaquults.

Plummer soils are geographically associated with Alapaha, Albany, Bibb, Chipley, Kinston, Leefield, Pansey, Pottsburg, Rutlege, and Surrency soils. Alapaha and Leefield soils have an argillic horizon at a depth of 20 to 40 inches. Also, Leefield soils are somewhat poorly drained. Albany soils have an argillic horizon at a depth of 40 to 80 inches and are somewhat poorly drained. Bibb and Kinston soils are stratified and very poorly drained. Chipley and Pottsburg soils are sandy to a depth of at least 80 inches. Also, Chipley soils are somewhat poorly drained and Pottsburg soils have a spodic horizon. Pansey soils have an argillic horizon within a depth of 20 inches. Rutlege and Surrency soils are very poorly drained.

Typical pedon of Plummer sand, 0 to 5 percent slopes; about 950 feet north and 3,000 feet east of the southwest corner of sec. 21, T. 1 S., R. 11 W.

• A—0 to 8 inches; very dark gray (10YR 3/1) sand; weak fine granular structure; very friable; common fine roots; extremely acid; clear smooth boundary.
• Eg1—8 to 16 inches; grayish brown (10YR 5/2) sand; single grained; loose; few fine roots; very strongly acid; clear smooth boundary.
• Eg2—16 to 31 inches; light gray (2.5Y 7/2) sand; few fine prominent strong brown (7.5YR 5/8) masses of iron accumulation; single grained; loose; very strongly acid; clear smooth boundary.
• Eg3—31 to 41 inches; light gray (2.5Y 7/2) sand; common fine prominent brownish yellow (10YR 6/6) masses of iron accumulation; common splotches of white (10YR 8/1) uncoated sand; single grained; loose; very strongly acid; gradual smooth boundary.
• Eg4—41 to 68 inches; light gray (2.5Y 7/2) sand; many medium distinct pale yellow (2.5Y 7/4) and many fine prominent brownish yellow (10YR 6/6) masses of iron accumulation; single grained; loose; very strongly acid; clear smooth boundary.
• Btg—68 to 80 inches; light gray (10YR 7/2) sandy loam; few coarse distinct light yellowish brown (10YR 6/4) and few fine prominent brownish yellow (10YR 6/8) masses of iron accumulation; weak coarse subangular blocky structure; very friable; sand grains bridged and coated with clay; very strongly acid.

The thickness of the solum ranges from 72 to 100 inches. Reaction ranges from extremely acid to strongly acid throughout, except where lime has been applied.

The A or Ap horizon has hue of 10YR or 2.5Y, value of 2 to 4, and chroma of 1 or 2; or it is neutral in hue and has value of 2 to 4. Where value is 2 or 3, the horizon is less than 8 inches thick.

The Eg horizon has hue of 10YR or 2.5Y, value of 5 to 8, and chroma of 1 or 2; or it is neutral in hue and has value of 5 to 8. It has few or common masses of iron accumulation in shades of yellow and red. It is sand, fine sand, or loamy sand.

The BEg horizon, where present, has hue of 10YR to 5Y, value of 5 to 7, and chroma of 1 or 2; or it is neutral in hue and has value of 5 to 7. It is loamy sand or loamy fine sand.

The Btg horizon has hue of 10YR to 5Y, value of 5 to 7, and chroma of 1 or 2; or it is neutral in hue and has value of 5 to 7. It has few to many masses of iron accumulation in shades of yellow and red. It is sandy loam, fine sandy loam, or sandy clay loam. In some pedons, it has pockets of loamy sand and sandy clay. The Btg horizon is 13 to 35 percent clay.
