It has been said, “If you want to know something about the soil, ask the soil.” The logic behind this thought rings true. Not a day passes that soil surveyors the world over are not asking their questions of the soil, questions that are unveiling a fascinating , yet useful and timely science – the science of the soil. However, the surface of the earth, yes, even the land embraced by our United States and the limitless number of soils to which it is parent, is far too great for one man or group of men to know intimately. Familiarization with the soils which they are associated in their particular state it section of the country is the extent of their working knowledge. Such a condition exists among trained soil observers; men who thought their experience and knowledge, are able to draw conclusions from what they see. The same condition to a more acute degree exists among farmers and laymen. These men are untrained for such observations, yet they are expected to control the dynamic medium on which they live. A method that should be helpful is a block diagram presentation. In this case, a treatment of South Dakota soil associations showing morphological, topographic, and geologic relationships, is involved. The emphasis is placed in pictorial representation of land forms and the correlated position of associated soil types over the existing parent materials. This study involved eight soil associations covering the entire state of South Dakota.
