The object of this study was to compare several legumes with each other as to their effectiveness in improving the soil when grown in short rotations, and subjected to different treatments. The relative soil improvement benefits of each legume are based on: 1) The amount of forage and roots produced during the growing season under several cutting treatments. 2) The nitrogen content of the forage and roots.

Six varieties of alfalfa, two hardy, and four non-hardy ones, an annual and a biennial sweetclover, and two varieties of vetch were grown at the Agricultural Experiment Station Farm of the University of Nebraska at Lincoln, during the growing season of 1952.
