Learning about Soil Parent Materials in Ohio: Use of Online Maps in the Classroom, Lab, and Field.

The Factors of Soil Formation are central to the science of Pedology, and consequently are emphasized in Soil Science classes from introductory to advanced levels. Particularly in relatively young landscapes, Parent Material influences on soil character and geographic distribution are often both well-expressed and instructive for students beginning to grasp fundamental concepts of soil genesis and geography. Interactive visual depictions of major Soil Parent Materials are highly effective in helping students understand significant geographic aspects of geological history, and the influence of surficial materials on soil distribution and important soil properties. The development of online Soil Parent Material maps for Ohio soils and their application in the classroom, lab, and field is discussed.
