Photograph of Orville Austin standing in a recently seeded field of hairy vetch and Balboa rye. The back of the photograph proclaims, "Combination planting of hairy vetch (20#) and Balboa rye (1 bu.) seeded with combination (16 disk, 7-inch spacing) drill with fertilizer and grass seeder attachments with 175 lbs. of superphosphate applied per acre at time of planting. This field was planted to hairy vetch and Balboa rye and seed crop was harvested in July 1942 with combine. The straw and stubble remained on the field until immediately before the present (1942) seeding. This field was prepared for the 1942 seeding going over the field three times with a tandem disk and tractor followed with two times over 6 ½ ft. field cultivator attached to the tractor, followed by one time over with tandem disk before planting with the above combination fertilizer, disk, and grain drill and seeded on September 17, 1942."

Photograph of the combination planting of oats and vetch in an apple orchard in Lowell, next to Highway #71. The back of the photograph proclaims, "Combination planting of vetch and oats in apple orchard. Cover crop has been cut into the soil with tractor and double disk to serve as a mulch in the orchard. A common practice over a number of years in this orchard. Growth of vetch and oats in the foreground was left unplowed and serves as a border strip along the highway. This strip helps to show this amount of green manure that has been cut into the soil to serve as orchard mulch."

Photograph of increased beef production through the retirement of upland cultivated land to Bermuda grass pasture as reported by Mr. R. L. Simpson, Jr. of Eufaula, Oklahoma. 25 Aberdeen Angus cattle grazed on 26 acres of this Bermuda pasture from early spring until late fall. In March or April, 1940, pasture was sodded and then 350 pounds of 20% superphosphate fertilizer per acre was spread, then overseeded to lespedeza in 1941 and then to yellow hops and bur clovers in the fall of 1942. 14 acres described as “almost blow sand” were taken out of cultivation; another 14 acres were low lying drains that had developed brush and sprouts but which were cleared. Cattle grazing pasture which was still in good condition at the time of the photograph was taken. OK-8411.
