The Prairie Soils have been regarded as a unique group because their characteristics are in contrast to those of soils correlated with the Brown Forest Soil Group with which their occurrence is associated. This fact indicates that some factor or factors other than climate have dominated their development. Various writers have proposed grouping the Prairie Soils with the Black Earths, others with the Rendzinas, and some have suggested that they are Wiesendoden. In the United States Doctor Marbut has included them in his Pedalfer group because their development has taken place under the influence of the predominating downward movement of water. He placed them in a separate group under that category because he thought they were characterized by a high organic content which he believed to be the result of the operation of a dynamic force. The correctness of this latter supposition will be discussed later. It is the purpose of this paper to discuss the environment, morphology, and genesis of the Prairie Soils. The writers do not feel that there is yet a sufficient body of facts available to warrant satisfactory conclusions regarding the genesis of the Prairie Soils. Recent studies have added to the knowledge of the morphological features of this group and have influenced a change of opinion of their origin.
