The poorly drained Beauford soils contain more clay than the Lura soils and are associated with them in a few places. The somewhat poorly drained Collinwood and the poorly drained Waldorf soils formed in 48 inches or more of lacustrine sediments and have sola with texture similar to that of the Lura soils. The somewhat poorly drained Guckeen and the poorly drained Marna soils formed in a mantle of clayey lacustrine sediments and have loamy glacial till within depths of 40 inches. Very poorly drained and poorly drained. Surface runoff is slow to ponded.
Permeability is slow.
An apparent seasonal high water table for the undrained phase is at 1 foot above the surface to 1 foot below at some time during November to July in most years for the very poorly drained phase and 1.0 feet to 3 feet for the poorly drained phase. Most Lura soils are cultivated. Corn and soybeans are the principal crops. Native vegetation was a wet plant association of the tall grass prairie. South central Minnesota and possibly north-central Iowa.
