The moderately wet phase has a perched water table at a depth of 1.5 to 3.5 feet at some time between February and June in most years. Runoff is medium on the gentle slopes and rapid on the steep slopes. Permeability is moderate in the loess and slow in the residuum weathered from shale. Marseilles soils are used for pasture, cropland, and woodland. Cultivated crops are corn, soybeans, small grain, and meadow.
Native vegetation is deciduous hardwoods.
Extent is moderate. La Salle County, Illinois, 1969. With this revision, the typical pedon is moved from La Salle County to Bureau County. A new typical pedon was selected to depict a more typical landform position and slope. These soils have a seasonally perched water table on the shale bedrock and water that moves laterally along the surface of the bedrock, but they do not have an aquic moisture regime.
