KALAMAZOO SERIES


The Kalamazoo series consists of very deep, well drained soils formed in loess-influenced loamy outwash overlying sand, loamy sand, or sand and gravel outwash on outwash plains, terraces, valley trains, and low lying moraines. Slope ranges from 0 to 18 percent. Saturated hydraulic conductivity is moderately low to moderately high in the loamy materials and high in the sandy materials. Mean annual precipitation is about 944 mm (37in), and mean annual temperature is about 9.4 degrees C (49 degrees F).

Amanda, Caprell, Conestoga, Crouse, Greybrook, Hickory, Hollinger, Kanawha, Kidder, Richardville, Senachwine, Skelton, Wawaka, and Wawasee soils lack sandy textures in the lower part of the series control section. Belmont, High Gap, Lumberton, Military, Pignut, and Woodbine soils have a lithic contact within a depth of 152 cm (60 in). Belmore soils average more than 5 percent clay in the lower part of the series control section. Chili soils formed in outwash composed mainly of non-calcareous sandstone and shale with a large amount of quartz gravel. Cliftycreek, Gallman, Martinsville, Ockley, Princeton, and Riddles soils are deeper than 102 cm (40 in) to the base of the argillic horizon. Kosciusko, Leroy, and Strawn soils are less than 102 cm (40 in) to carbonates. Mocksville and Turnersburg soils consist of residuum from intermediate or mafic metamorphic or igneous rock. Relay soils have coarse fragments dominated by gabbro, granodiorite or metagabbro and have hues of 2.5Y to 5GY in the B horizons.

GEOGRAPHIC SETTING: Kalamazoo soils are on outwash plains, terraces, valley trains, and low lying moraines. Slope ranges from 0 to 18 percent. The Kalamazoo soils formed in loess-influenced loamy outwash overlying sand, loamy sand, or sand and gravel outwash. Mean annual precipitation ranges from 889 to 1004 mm (35 to 40 in). Mean annual temperature from 8.0 to 10.1 degrees C (46 to 50 degrees F).

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Boyer, Bronson, Dowagiac, Matherton, Oshtemo, Sebewa, Schoolcraft, Sleeth, Spinks, and Volinia soils. The coarser textured Boyer, Oshtemo, and Spinks are associated in some areas. Moderately well drained Bronson, somewhat poorly drained Matherton and Sleeth, and very poorly drained Sebewa soils are the most common associates. Also associated are the Dowagiac, Schoolcraft, and Volinia soils which are Mollisols and occur in areas of former prairie.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained. Potential for surface runoff is negligible to medium depending on slope gradients. Saturated hydraulic conductivity is moderately low to moderately high in the loamy materials and high in the sandy materials.

USE AND VEGETATION: A large part is cropped to corn, wheat, soybeans, and hay. A small part is in pasture. Some areas adjacent to the larger cities are idle cropland. Native vegetation is forest consisting of northern red oak, white oak, black oak, sugar maple, black cherry, American basswood, tulip tree, red maple, black walnut, pignut hickory, and shagbark hickory.

DISTRIBUTION AND EXTENT: MLRAs 97, 98, and 111C in southern Michigan and northern Indiana. The series is of large extent.
