Loran soils contain mottles with chroma of 2 or less higher in the solum and have a mollic epipedon. They formed in materials similar to Marseilles soils, but are deeper to the paralithic contact. Moderately well drained and well drained. 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.
