SWEETCLOVER was used as a green manure in crop rotations at the Washington Agricultural Experiment Station in 1921 and at the Idaho Station in 1923. Results of these trials are summarized (7, 1). Rotations including sweetclover from which soil and water losses were determined began at the Palouse Conservation Experiment Station in 1933 (4). Rotations including sweetclover were used on farms in demonstration projects in 1934 and later in soil conservation districts (9). These rotations have been studied to determine their influence on conservation and the farming enterprise (11). Many of the legume plantings for soil conservation were used as dual-purpose crops. They were utilized for pasture in the late spring and plowed for green manure in the early summer. Grazing trials; with sweetclover-grass mixtures have been reported (6). Early observations of mixtures of grass and sweetclover as compared with sweetclover alone indicated that erosion control was increased, yield of forage was essentially the same as from sweetclover, danger of bloating grazing ani-
