HANNA SERIES
Hanna soils typically have dark grayish brown loam or sandy loam Ap horizons, mottled dark yellowish brown to dark brown loam and sandy loam B horizons and C horizons of stratified sand and loamy materials.
TAXONOMIC CLASS: Coarse-loamy, mixed, active, mesic Aquultic Hapludalfs
TYPICAL PEDON: Hanna sandy loam on a nearly level convex slope under grass. (Colors are for moist soil unless otherwise stated.)
Ap--0 to 6 inches; dark grayish brown (10YR 4/2) sandy loam; moderate medium granular structure; friable; many fine roots; 10 percent coarse fragments; neutral; abrupt smooth boundary. (6 to 10 inches thick)
A2--6 to 9 inches; dark brown (10YR 4/3) sandy loam; moderate medium and coarse granular structure; friable; few fine roots; 10 percent coarse fragments; strongly acid; clear wavy boundary. (0 to 10 inches thick)
B1--9 to 13 inches; dark brown (10YR 4/3) sandy loam; weak medium subangular blocky structure; friable; few fine roots; 5 percent coarse fragments; very strongly acid; clear wavy boundary. (0 to 8 inches thick)
B21t--13 to 18 inches; dark yellowish brown (10YR 4/4) loam; moderate medium subangular blocky structure; friable; few fine roots; 5 to 10 percent coarse fragments; thin patchy clay films on faces of peds and as bridging between sand grains; very strongly acid; clear wavy boundary.
B22t--18 to 26 inches; brown (10YR 5/3) loam; many fine light brownish gray (10YR 6/2) mottles; weak medium subangular blocky structure; friable; few fine roots; thin patchy clay films on faces of peds and as bridging between sand grains; 5 percent coarse fragments; very strongly acid; clear wavy boundary.
B23t--26 to 31 inches; mottled dark yellowish brown (10YR 4/4) and light brownish gray (10YR 6/2) sandy loam; weak coarse subangular blocky structure; friable; 15 percent coarse fragments; thin clay films on sand grains and as bridging between sand grains; strongly acid; clear wavy boundary. (Combines thickness of the B2 horizon is 14 to 30 inches)
IIB3--31 to 65 inches; mottled yellowish brown (10YR 5/4), gray (10YR 6/1) and grayish brown (10YR 6/2) stratified loamy sand, sand and sandy loam; 10 to 15 percent, coarse fragments; single grained; loose; strongly acid; gradual wavy boundary. (18 to 40 inches thick)
IIC--65 to 115 inches; yellowish brown (10YR 5/4) sand; common grayish brown (10YR 5/2) mottles; single grained; loose; 5 percent coarse fragments; pH 5.6 medium acid.
TYPE LOCATION: LaPorte County, Indiana; 360 feet north and 1 foot west of the Center of sec. 31, T. 35 N., R. 4 W.
RANGE IN CHARACTERISTICS: Sola are typically 40 to 60 inches thick and range from 36 to 70 inches in thickness. Few shale fragments are throughout the soil. The amount of gravel in the sola ranges from less than 5 percent to 20 percent and occasionally up to 30 percent in the lower B horizon.
The Ap horizon has 10YR hue, value of 3 or 4 and 2 through 4 chroma. It is a sandy loam or loam. The A2 horizon has 10YR hue, value of 4 or 5 and 3 through 5 chroma. It is sandy loam or loam.
The B2t horizon has dominant hue of 10YR or 7.5YR, value of 4 or 5 and 3 through 6 chroma. Mottles with chroma of 2 or less occur in the upper 10 inches of the argillic horizon. It is dominantly loam and sandy loam and individual horizons are sandy clay loam or clay loam. The Bt horizon averages between 14 and 18 percent clay. It commonly has moderate or weak medium or coarse subangular blocky structure. This horizon ranges from strongly to very strongly acid.
The C horizon is typically stratified layers of sand, gravelly sand, sandy clay loam and loam and contains few to many shale fragments. It commonly is medium or strongly acid. Materials containing free carbonates occur at depths of 6 feet or more.
COMPETING SERIES: This is the only series in the family.
Alida,
Bronson,
Lydick,
Oshtemo and
Tracy soils are in closely related families. Alida soils have darker colored surface soils. Bronson soils have a higher base saturation. Lydick soils have darker surfaces and lack low chroma mottles. Oshtemo soils have a higher base saturation and lack low chroma mottles. Tracy soils lack low chroma mottles.
GEOGRAPHIC SETTING: Hanna soils are typically on level or nearly level topography. Slopes are commonly 2 percent or less. Hanna soils are formed in glacial outwash containing a high amount of shale fragments and a low amount of carbonates. Summers are hot and winters are cold. Mean annual temperature ranges from 45 to 57 degrees F. and annual average precipitation ranges from 30 to 40 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: The Hanna soils are in a drainage sequence with the well drained
Tracy and the poorly drained
Quinn soils. The
Lydick and
Alida soils are formed in similar materials and are transitional to Mollisols.
DRAINAGE AND PERMEABILITY: Moderately well drained. Runoff is slow. Permeability is moderate in the solum and rapid in the underlying material.
USE AND VEGETATION: Soils are cultivated. Corn, soybeans, small grain and hay are major crops. Native vegetation was mixed forest.
DISTRIBUTION AND EXTENT: Northern Indiana and possibly southern Michigan. The series is of moderate extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: AMHERST, MASSACHUSETTS
SERIES ESTABLISHED: LaPorte County, Indiana, 1934.
REMARKS: The Hanna series was formerly classified as weakly developed Planosols in the region of Gray-Brown Podzolic soil. More recently it has been classified as Typic Hapludalfs, fine-loamy, mixed, mesic. The change to the present classification is based on a thorough study of these soils in LaPorte and Porter Counties where the series has dominantly been used. To our knowledge the series has never been used in other states. In areas where the series has dominately been used in the past, it will classify Aquultic Hapludalfs, coarse-loamy, mixed, mesic.
