LOCATION INGERSOLL MIEstablished Series
TAXONOMIC CLASS: Fine-silty, mixed, semiactive, mesic Aquic Hapludalfs
TYPICAL PEDON: Ingersoll silt loam - on a west facing 2 percent slope in a cultivated field. (Colors are for moist soil unless otherwise stated.)
Ap--0 to 9 inches; dark grayish brown (10YR 4/2) silt loam, light brownish gray (10YR 6/2) dry; moderate medium granular structure; friable; many fine and medium roots; mildly alkaline; abrupt smooth boundary. (7 to 10 inches thick)
Bt--9 to 12 inches; brown (7.5YR 5/4) silt loam; common medium prominent gray (10YR 5/1) mottles; weak fine angular blocky structure; friable; many fine roots; few dark yellowish brown (10YR 3/4) organic stains; few thin clay films; mildly alkaline; clear wavy boundary. (3 to 15 inches thick)
C1--12 to 15 inches; pale brown (10YR 6/3) silt loam; many medium distinct gray (10YR 5/1) and common medium distinct yellowish brown (10YR 5/6) mottles; weak fine subangular blocky structure; friable; many fine roots; slight effervescence; moderately alkaline; gradual wavy boundary.
C2--15 to 30 inches; yellowish brown (10YR 5/4) silt loam and very fine sand; few fine distinct gray (10YR 5/1) and grayish brown (10YR 5/2) mottles; weak coarse subangular blocky structure; friable; few fine roots; strong effervescence; moderately alkaline; gradual wavy boundary.
C3--30 to 34 inches; pink (5YR 7/3) and light gray (5Y 7/1) stratified light silty clay loam and heavy silt loam; massive; friable; very few roots; many white (10YR 8/1) lime segregations; strong effervescence; moderately alkaline; abrupt irregular and broken boundary.
C4--34 to 60 inches; brown (10YR 5/3) silt loam and very fine sand; common medium distinct gray (10YR 5/1) mottles; massive; friable; strong effervescence; moderately alkaline.
TYPE LOCATION: Midland County, Michigan; 2 miles south and 4 miles east of Edenville; 660 feet east and 330 feet south of the center of sec. 14, T. 16 N., R. 1 E.
RANGE IN CHARACTERISTICS: Thickness of the solum is typically 10 to 18 inches, but ranges to 24 inches, which coincides with the depth to effervescent material. The solum ranges from slightly acid to mildly alkaline. Gravel content ranges from 0 to 3 percent by volume throughout the profile.
The Ap horizon has hue of 10YR, value of 3 or 4, and chroma of 2 or 3. Uncultivated areas may have A and E horizons. The A horizon has hue of 10YR, value of 2 or 3, and chroma of 1 or 2 and ranges in thickness from 3 to 5 inches. The E horizon has hue of 10YR, value of 4 or 5, and chroma of 2 or 3. The A and E horizons are silt loam, fine sandy loam, or very fine sandy loam.
The Bt horizon has hue of 5YR to 2.5Y, value of 4 or 5, and chroma of 3 or 4. It is silty clay loam, silt loam, or clay loam. Some pedons have thin strata of very fine sand, loamy fine sand, fine sandy loam, or sandy loam.
The C horizons have hue of 5YR to 5Y, value of 5 to 7, and chroma of 1 to 4. It is stratified silt loam, very fine sand, loamy very fine sand, and silty clay loam.
COMPETING SERIES: These are the Blair, Fishhook, Glenford, Henshaw, Keene, Lykens, Muren, Sardinia, Story, and Xenia series in the same family. All of these have thicker sola and do not have carbonates within a depth of 18 inches.
GEOGRAPHIC SETTING: Ingersoll soils are on lake plains, outwash plains and deltas of Wisconsinan Age. Slope gradients range from 0 to 6 percent. They formed in stratified calcareous silt loam, very fine sand, and silty clay loam containing lenses of finer and coarser texture. Mean annual precipitation ranges from is 28 to 34 inches, and the mean annual temperature ranges from 44 to 48 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: The Ingersoll soils are associated in the landscape with the poorly drained Colwood and Pella soils, the somewhat poorly drained Dixboro and Kibbie soils, and the moderately well drained Tuscola soils. Dixboro is a coarse-loamy soil and Kibbie has a thicker solum.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained. Runoff is slow. Permeability is moderate.
USE AND VEGETATION: Ingersoll soils are largely under cultivation. Major crops are corn, field beans, soybeans, sugar beets, hay, and small grain.
DISTRIBUTION AND EXTENT: Central Michigan. The series is of small extent.

REMARKS: Laboratory data available: 74L508-74L511 and 74L516-74L521. Diagnostic horizon and features recognized in this pedon are: ochric epipedon - the zone from the surface to 9 inches (Ap horizon); argillic horizon - the zone from 9 to 12 inches (Bt horizon); aquic feature - mottles with chroma of 2 or less in the upper 10 inches of the argillic horizon.
