Abstract
This research compared the parent materials of loess, glacial till, and a soil mixture of the b and the underlying c1 loess and c2 glacial till horizons with the b horizon replacement. Animal manure, green manure, and a forage grass-legume "organic building" crop were incorporated into the surface of each rooting medium to compare with topsoil replacement. The objectives of the study were to (1) characterize the physical and chemical properties of the selected parent materials, (2) determine soil moisture regimes for each selected rooting medium during the growing seasons, (3) evaluate alternative organic amendments incorporated in the surface of the selected parent materials compared with topsoil replacement, and (4) determine the suitability of selected parent materials on prime farmlands as a replacement for suggested b horizon as rooting mediums for corn and soybeans. In the 1984 growing season, the rainfall was somewhat higher and better distributed and the temperatures were lower than in the 1982 and 1983 production seasons. Thus, the corn yields were much higher in 1984 for the glacial till soil materials. The other three soil materials were used during the growing season by a coal company for their mining operations. However, the crop yield trends on the glacial till soil material can be extrapolated to the other three soil materials.
