EDINA SERIES
The Edina series consists of very deep, poorly drained soils formed in loess. These soils are on flats and in depressions on uplands. Slope ranges from 0 to 2 percent. Mean annual precipitation is about 889 mm (35 inches), and mean annual temperature is about 11 degrees C (52 degrees F).

COMPETING SERIES: These are the
Barbert,
Crestmeade,
Filbert,
Fillmore,
Massie,
Scott,
Sturges, and
Triplett series. Barbert soils have mean annual soil temperature of less than 11 degrees C (51 degrees F) in the control section. Crestmeade soils have mean annual soil temperature of more than 13 degrees C (56 degrees F) in the control depth. Filbert soils are more than 152 cm (60 inches) to the base of the argillic horizon. Fillmore soils are at elevations above 335 feet (1100 feet) and typically have a thicker mollic epipedon. Massie and Scott soils are in areas that receive less than 865 mm (34 inches) of mean annual precipitation. Sturges soils have a subhorizon of the upper part of the argillic horizon with chroma greater than 2 in the mtarix. Triplett soils have more than 10 percent sand in the lower part of the argillic horizon.
GEOGRAPHIC SETTING: The Edina soils are on flats and in shallow closed depressions on uplands. Slope ranges from 0 to 2 percent. The soils formed in loess. Mean annual temperature ranges from 9 to 12 degrees C (49 to 54 degrees F). Mean annual precipitation ranges from 865 to 1040 mm (34 to 41 inches). Frost-free period is 175 to 200 days. Elevation is 200 to 335 meters (655 to 1100 feet) above mean sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Grundy,
Haig,
Seymour, and
Belinda soils. Grundy, Haig, and Seymour soils do not have an albic horizon. Belinda soils have a thinner, dark colored surface layer. Grundy and Seymour soils commonly are on more sloping areas. Haig and Belinda soils are on similar positions.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Poorly drained. Depth to the top of a perched seasonal high water table ranges from 10 to 50 cm (4 to 20 inches) between November and April in normal years. These soils are subject to ponding where they occur in depressions. Potential for surface runoff is negligible in depressions, and ranges to high on the flats. Saturated hydraulic conductivity is low. Permeability is very slow or slow.
USE AND VEGETATION: Most areas are used to grow corn, hay, small grain, and soybeans. Native vegetation is prairie grasses. See Additional Data section for native vegetative cover in Iowa.
DISTRIBUTION AND EXTENT: MLRA 109 and LRUs 108C, 108D, and 115B in Missouri and Iowa. The type location is in MLRA 109. The series is of large extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Indianapolis, Indiana.
SERIES ESTABLISHED: Knox County, Missouri, 1907.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Mollic epipedon: from the surface of the soil to a depth of 23 cm and from a depth of 46 to 71 cm (Ap, Bt, and Btg1 horizons).
Albic horizon: from a depth of 23 to 46 cm (E horizon).
Argillic horizon: from a depth of 46 to 137 cm (Bt and Btg horizons).
Abrupt textural change: at a depth of 46 cm, at the contact of the E and Bt horizons.
Aquic conditions: redox features visible in all horizons below a depth of 23 cm.
11/2015 revision: based on review of Edina data during the SDJR Initiative, the concept of Edina series was narrowed to only include poorly drained soils.
ADDITIONAL DATA: In Iowa, the native vegetative cover is a herbaceous wetland community commonly inhabited with Bluejoint Grasses, Fowl Bluegrasses, Green Muhlies, Fox Sedges, Field Sedges, Dudleys Rushes, Torreys Rushes, Swamp Milkweeds, False Sneezeweeds, False Asters, New England Asters, White Panicled Asters, and Wild Mints.
