The Hastings series consists of very deep, well drained soils on uplands. They formed in silty loess.
Permeability is moderately slow.
Slope ranges from 0 to 17 percent. Mean annual temperature is 54 degrees F, and mean annual precipitation is 26 inches at the type location. Hastings silt loam, with a slope of less than 1 percent, in a cultivated field. Solum thickness ranges from 26 to 52 inches and thickness of the mollic epipedon ranges from 8 to 20 inches. Typically, the A horizon and the upper part of the B horizon make up the mollic epipedon.
