COMPETING SERIES: These are the Algansee, Altmar, Birchwood, Brems, Brockatonorton, Deerfield, Elnora, Fortress (T), Meckling (T), Ottokee, Partridge, Tedrow, and Zaborosky series. Algansee soils have textural stratification in the lower part of the series control section. Altmar soils have more than 7 percent rock fragments in the particle-size control section. Birchwood soils have a densic contact within the series control section. Brems and Elnora, soils do not have iron depletions within a depth of 24 inches. Brockatonorton soils have a buried histic epipedon within the series control section. Deerfield soils are in LRR R and in areas with a mean annual precipitation of greater than 35 inches. Fortress soils have a B horizon that is less than 10 inches thick. Meckling soils are calcareous throughout. Ottokee soils have lamella within the series control section. Partridge soils have a lithic contact between a depth of 20 and 40 inches. Tedrow soils are less acidic that moderately acid in the lower part of the series control section. Zaborosky soils have carbonates within a depth of 60 inches.
GEOGRAPHIC SETTING: Morocco soils formed in sandy outwash and are on swells on outwash plains and rises on lake plains. The sand fraction is fine or medium sand. Slope gradients range from 0 to 3 percent. Mean annual temperature ranges from 47 to 53 degrees F., mean annual precipitation ranges from 30 to 42 inches, frost-free period ranges from 120 to 180 days, and elevation ranges from 580 to 1,530 feet above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Brems, Maumee, Newton, Osolo, Plainfield, and Tyner soils. The moderately well drained Brems soils are on higher swells. The very poorly drained Maumee and Newton soils are in depressions. The well drained Osolo soils are on slightly higher positions on swells. The excessively drained Plainfield and Tyner soils are on swells and knolls.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained. The potential for surface runoff is negligible. Permeability is rapid. The depth to the top of an apparent seasonal high water table ranges from 0.5 to 2.5 feet for some time in normal years.
USE AND VEGETATION: Soils are mostly used to grow corn, soybeans, and wheat. Irrigation is a common practice on cropped areas. Some areas are in pasture or forest. Native vegetation is forest.
DISTRIBUTION AND EXTENT: MLRA's 95A, 97, 98, 105, and 110 in northern Indiana, southern Michigan, northeastern Illinois, and central Wisconsin. The soils are of large extent.
MLRA OFFICE RESPONSIBLE: Indianapolis, Indiana.
SERIES ESTABLISHED: Fulton County, Indiana, 1943.
REMARKS: Diagnostic horizons and features recognized in this pedon are:
Ochric epipedon: from the surface to 14 inches (Ap and E horizons)
Aquic conditions: redoximorphic features present from 9 to 60 inches (E, Bw, Bg, C1 and C2 horizons)
NASIS Data Mapunit ID 124289 represents the typical pedon.
NASIS Data Mapunit ID 401576 represents Morocco in complex with Brems soils.
ADDITIONAL DATA: Lab characterization data is available for the typical pedon (JR7801) from the Purdue University Soil Characterization Laboratory, AES Bulletin No. 323, Volume 6, Pg. 154. Transect data (T98IN-131-001) for the typical pedon is on file in the MLRA project office, Plymouth, Indiana. Transect shows 80 percent Morocco soils and 20 percent Brems soils.
