MCBRIDE SERIES

The McBride series consists of very deep, well drained and moderately well drained soils that are moderately deep to a fragipan. The McBride soils formed in till and are on ground moraines and end moraines. Slope ranges from 2 to 45 percent. Mean annual precipitation is about 813 mm (32 inches), and the mean annual temperature is about 6.7 degrees C (44 degrees F).

COMPETING SERIES: There are no other series in the same family.

GEOGRAPHIC SETTING: The McBride soils are on ground moraines and end moraines of Wisconsinan Age. Slope gradients typically are of 2 to 18 percent, but range from 2 to 45 percent. These soils are formed in till. Mean annual precipitation ranges from 711 to 813 mm (28 to 32 inches). Mean annual temperature ranges from 6.1 to 7.8 degrees C (43 to 46 degrees F).

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Coral, Ensley, Montcalm, and Nester soils. The somewhat poorly drained Coral and the poorly drained Ensley soils are in the same drainage sequence. The well drained, sandier Montcalm soils and the finer textured Nester soils are nearby in most areas.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Moderately well drained. Potential for surface runoff is medium to very high depending upon slopes. Saturated hydraulic conductivity is high in the upper part, moderately low in the fragipan, and moderately high in the lower part of the pedon. Permeability is moderately rapid in the upper part, slow in the fragipan, and moderately slow in the lower part of the pedon.

USE AND VEGETATION: A large part of the milder slopes is cropped to small grains, legume-grass hay, corn, and navy beans. Potatoes comprise a major acreage in some areas. Other areas are in woodland or permanent pasture. Tree species include chiefly sugar maple, American beech, northern red oak, and American basswood.

DISTRIBUTION AND EXTENT: MLRAs 94A, 96, and 98 in the northern half of the lower peninsula of Michigan. The series is of large extent.
