Book excerpt: Excerpt from Development and Significance of the Great Soil Groups of the United States Many of these early Studies Of soil from the geological point Of view were fruitful, provided comparisons were confined within small areas in which conditions Of climate, native vegetation, relief, and age were essentially uniform. But without definite knowledge Of the soil characteristics as such, even these results were difficult to inter pret in terms Of native or cultural plants. The confusion, as may be seen from what follows, came about by assuming that a direct relationship exists between the nature Of rocks and Of the soil that develops from their weathered products; whereas many other factors, especially constructional biological forces, more frequently dominate the situation in soil development.
