Photograph of a planned conservation treatment of timbere4d rock free soil in Ouachita Highlands. Bermuda grass from seed on dozer cleared land 2 months after seeding. This grass was limed and fertilized with 150 pounds of 10-20-10 per acre. Land was tandem diced, followed by packing rain. Seed and fertilizer placed on top of ground in 18 inch rows. Seeded at the rate of 2 pounds of seed per acre.

Photograph of Sericea lespedeza. The grass is cut and raked in windrows on 4 acres of an idle, cultivated field, which was seeded at the rate of 25 pounds per acre on June 10, 1942 with a cyclone seeder. The field was flattened, disked and harrowed. Three and one half acres were fertilized with 200 pounds of 20% phosphate per acre and the seed bed packed with a cultipacker. Seeds were covered with a second rolling of the cultipacker. A severe drought in 1943 prevented all but one hay crop. Freddie Brown, the District Supervisor, estimated that he harvested 1.5 tons of hay per acre for a total of 6 tons. One hay crop in 1944 yielded 8 tons. A seed crop will be harvested later this year. One-half acre was left unphosphated at the time of seeding for a field test. The area phosphate yielded 50% more hay than the untreated area. Soil is very infertile. Adjacent land sodded to Bermuda grass in June and July, 1942 is living but making no growth whatever. L to R: Maynard Collins, Freddie Brown and John Moberly. OK-8961.
