OME tests with sweetclover as the green manure crop in a rotation S grown on Putnam silt loam on the South Farm of the Missouri Experiment Station in 1947 demonstrated that potassium as well as calcium is needed if this crop is to be a producer of considerable tonage of vegetative bulk. Potassium also demonstrated its service in raising the concentration of nitrogen in the crop, and, presumably thereby, the fixation of nitrogen from the atmosphere.
