Abstract

For adequate classification and mapping of soils it is necessary to learn as much as possible about their chemical and physical properties, their age, and the parent materials or geological materials from which they have formed. Soil properties which vary with age, texture (the particle size distribution), and lithology have significant bearing, for example, on use and management suggestions, corn suitability ratings, and tax assessment value of soils. Thus it becomes necessary to discriminate age differences and significant textural and lithologic variations in the materials being studied. In the case of most Iowa soils, these problems are held in common with students of Pleistocene geology.
