The stems and leaves are pubescent. Sand Zwcern.âThis is thought to be a cross between Medicago saliva and M. fakata. It has been grown successfully by the Michigan and Wisconsin Experiment Stations. Its production is still in the experimental stage, but it is proving hardy and a heavy yielder on light, sandy soils in Michigan. The flowers vary from yellow to purple. The seed came originally from Germany. Propagation and production. A deep, well-drained, non-acid, fertile soil reasonably free from weeds is required. Excessive alka- linity (in the West) is overcome by flooding and draining ; acidity (East) is corrected by liming. Well-rotted manure is a satisfac- tory fertilizer. A deep, permeable subsoil is necessary, as the roots normally extend to depths of six to twelve feet, and sometimes to considerably greater depths. (Fig. 275.) Inoculation of the seed or soil with root nodule bacteria is generally advisable in the humid regions. Repeated harrowings after plowing produce the fine well-settled seed-bed required. For seeding in the West, twelve to twenty pounds, and in the East, twenty to thirty pounds of seed per acre are used, broadcasted and harrowed or drilled in one and one-half inches deep, or less in clay soils, generally without a nurse crop.
