Soils formed from the glacial material

Ohio landscape

Most of the soils of northern and central Ohio have been formed from the glacial material deposited during the Pleistocene Epoch. The glacial soils are predominantly gray-brown podzols and once supported fine hardwood forests.

Soybeans, corn, wheat, and tomatoes are now the principal crops. Fertilization and liming are required in many areas. In the northwestern corner of the state, extensive drainage was necessary before the rich organic soils could be cultivated, and that area was the last part of Ohio to be settled. The alluvial soils along the major streams are also rich.

South of the glacial boundary, in southeast Ohio, the soils are much older and have been formed from the eroded shales and sandstones of the Appalachian Plateaus. The soils are thin and, because of the rough terrain, erosion has been severe, and much of the land has been returned to forest and pasture since the 1930s.
