Dyas, E. S.
"Soybeans have become a major crop in Iowa. They are well adapted to Iowa's climate and to general growing on the level Iowa soils where erosion is not a problem. The crop has more uses than most crops, both on the farm and in industry. Soybeans were first grown in Iowa for the home production of high-protein seed and hay. The seed has been used to substitute for purchased high-protein concentrates and the hay where legume hay is needed in the ration. More than half of the acreage has been harvested as hay. During the 10 years, 1929-1938, 64.5 percent has been harvested as hay, 30.5 percent for beans and the remaining 6 percent plowed under or grazed."--Page [35].
