Photograph of conservation crop rotation. Field of Class III and IV, 7-OH soil, planted with Bermuda sprigs in 1942 and 1943. Pastured continuously with no maintenance until the spring of 1955, at which time it was plowed and planted to Grass, Legume and Forb Cultivation. Bermuda made good growth after Grass, Legume and Forb Cultivation had matured. Land was plowed in the spring of 1956 and planted to corn with an application of 200 pounds of 10-20-10 fertilizer per acre at the time of planting corn. Corn was harvested in September and yielded 50 bushels per acre. The Bermuda was used for fall pasture followed by vetch and small grain. OK-371-8.
