INCE the water and minerals which a plant uses are obtained S from the soil through sorption by roots and root hairs, .it is obvious that the root system must be sufficient to satisfy these conditions for top growth. The ability of the root system to invade and permeate the soil is, therefore, of extreme importance in influencing top growth. In addition, there is a direct effect of roots on building soil organic matter and on such soil properties as structure, permeability, and resistance to erosion. The behavior of crop roots has been the subject of considerable investigation during the last quarter century. Weaver (9)3 and his students have made extensive field investigations and studies on soils classified as pedocals. However, root behavior on these soils is not typical of that found on the podzolic soils, even though the plant species grown are the same. Several studies have been made in the eastern states. Sprague’s (8) contributions on grasses in New Jersey is one of the most exhaustive. Other studies include root development and nodule formation on alfalfa in relation to pH at various depths by Pohlman (s), root development of potatoes in Ohio by Bushnell ( 3 ) , root development of orchard trees in New York by Oskamp and Batjer (4), and a similar study with orchard trees in West Virginia by Browning and Sudds
