Photograph of King Ranch Bluestem planted in the spring of 1947. On the right, hairy vetch, Austrian winter peas and animal sweetclover were planted in the fall, fertilized with 200 pounds superphosphate and cut into the soil just before grass planting. On the left, no legumes were used. Depleated soils should b conditioned with a legume ahead of grass seeding. Grass on the right made very favorable growth in spite of drought in 1947 and the first 8 months of 1948. TX-44, 917.
