USDA's description
The Eckrant series consists of well drained, moderately slowly permeable soils that are very shallow to shallow over indurated limestone bedrock. These nearly level to very steep soils soils formed in residuum derived from limestoneand occur on summits, shoulders, and backslopes of ridges on dissected plateaus. Slope ranges from 1 to 60 percent. Mean annual air temperature is about 18.9 degrees C (66 degrees F), and the mean annual precipitation is about 660 mm (26 in).
