(0 to 12 inches thick)
B/E--13 to 24 inches; dark yellowish brown (10YR 4/4) fine sandy loam (Bt); common medium faint grayish brown (10YR 5/2) and common medium distinct strong brown (7.5YR 5/6 and 5/8) mottles; moderate medium subangular blocky structure; friable; surrounded and coated by brown (10YR 5/3) fine sandy loam (E), light gray (10YR 7/2) dry; weak medium granular structure; friable; about 10 percent cobbles and 7 percent gravel; strongly acid; clear irregular boundary. (4 to 17 inches thick)
Bt1--24 to 43 inches; dark brown (7.5YR 4/4) fine sandy loam; many medium distinct strong brown (7.5YR 5/6, 5/8), common medium distinct grayish brown (10YR 5/2), and light brownish gray (10YR 6/2) mottles; moderate coarse subangular blocky structure; friable; thin brown (10YR 4/3) coatings on the faces of peds in the upper 10 inches of the horizon; distinct dark grayish brown (10YR 4/2) clay films on faces of peds; about 5 percent cobbles and 5 percent gravel; strongly acid; gradual wavy boundary.
Bt2--43 to 55 inches; dark yellowish brown (10YR 4/4) fine sandy loam; common medium distinct yellowish brown (10YR 5/6) and few coarse prominent light brownish gray (10YR 6/2) mottles; moderate coarse subangular blocky structure; friable; distinct very dark grayish brown (10YR 3/2) clay films on faces of peds; about 5 percent cobbles and 5 percent gravel; slightly acid; gradual wavy boundary. (The combined thickness of the Bt horizon ranges from 16 to 38 inches.)
C--55 to 65 inches; yellowish brown (10YR 5/4) fine sandy loam; few fine distinct yellowish brown (10YR 5/6) mottles; massive; friable; about 10 percent cobbles and 5 percent gravel; slight effervescence; moderately alkaline.
TYPE LOCATION: Jackson County, Michigan, about 1 mile southwest of the village of Sandstone; 1,400 feet west and 600 feet south of the northeast corner of sec. 3, T. 3 S., R. 2 W.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 40 to more than 60 inches. Depth to free carbonates ranges from 40 to more than 60 inches. Gravel content ranges from 2 to 20 percent by volume throughout the pedon. Cobble content ranges from 0 to 10 percent.
The Ap horizon has a hue of 10YR, value of 3 or 4, and chroma of 2 or 3. Undisturbed areas have an A horizon 2 to 5 inches thick with chromas of 2 or 3 and values of 1 or 2.
The A horizon is fine sandy loam, loam, or sandy loam.
The E horizon has a hue of 10YR, value of 5 or 6, and chroma of 2 to 4. The value dry is 7 or more. The E horizon is loam, sandy loam, or fine sandy loam. It is strongly to slightly acid.
The E portion of the B/E horizon consists of 2 to 5 mm thick coatings on vertical faces of peds of B material with colors like those described for the E horizon. The B portion of the B/E horizon has color and texture ranges like the Bt horizon. The Bt horizon has hue of 10YR or 7.5YR, value of 4 or 5, and chroma of 3 to 6. It is fine sandy loam, sandy loam, loam, or gravelly analogs of these textures. Clay films range from few and thin to many and thick. It is very strongly acid to neutral but is typically moderately acid to neutral. Some pedons have a BC horizon.
The C horizon is fine sandy loam, sandy loam, or loamy sand and is gravelly in some pedons. In some pedons the upper part of the C horizon does not effervesce with dilute HCl. The reaction of the C horizon ranges from neutral to moderately alkaline.
COMPETING SERIES: There are no other series in the same family. Closely related are the Capac and Locke series. Capac soils are fine-loamy and have lower chromas in their B horizon. Locke soils are mollic intergrades.
GEOGRAPHIC SETTING: Teasdale soils are on till plains and the smoother part of low moraines of Wisconsinan Age. Slopes range from 0 to 4 percent and mean annual precipitation ranges from 29 to 37 inches, and the mean annual temperature ranges from 47 to 53 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: The Teasdale soils are the somewhat poorly drained member of a drainage sequence that includes the well drained Hillsdale and poorly drained Barry soils. The well drained Riddles soils are common associates.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained. Surface runoff is slow. These soils have a seasonal high water table that ranges from 1 to 2 feet below the surface from November to May. Permeability is moderate.
USE AND VEGETATION: The greater proportion is under cultivation. Corn, wheat, soybeans, and legume-grass hay are the principal crops. A small portion is in pasture and forests. The native vegetation was hardwoods, chiefly American elm, white ash, American basswood, and hickory.
DISTRIBUTION AND EXTENT: Central and southern Michigan. The series is of moderate extent.

REMARKS: The Teasdale pedon was sampled and characterized as S75MI-075-1, Sample Nos. 760400-760405. Diagnostic horizons and features recognized in this pedon are: ochric epipedon - the zone from the surface to 13 inches (Ap and E horizons); albic horizon - the zone from 9 to 13 inches (E horizon ); glossic horizon - the zone from 13 to 24 inches (B/E horizon); argillic horizon - the zone from 13 to 55 inches (B part of B/E, Bt1 and Bt2 horizons).
