Photograph of healing/healed sheet erosion on this cotton field located at the Blackland Experiment Station. The back of the photograph proclaims, "Sheet Erosion. After one rain, cross slope runoff on this down hill [sic], straight rowed field cut shallow gullies (4" deep) to the depth of bedded rows. Since then, cotton in the field has been cultivated once or twice and visual evidence of erosion has almost been obliterated. Damage to the field remains unaltered, however."

Photograph of Ten acre field of alfalfa planted following 2 years of sweet clover, where lime was applied. Sweat clover and alfalfa received application of 48% superphosphate at a rate of 150 pounds per acre. Alfalfa seeded in the fall of 1942 after a field of sweat clover was turned under in the summer of 1942. This method of seeding alfalfa following the sweet clover helps insure complete inoculation of alfalfa. Part of the field seeded to common variety of alfalfa & the rest to the Grimm variety. Recently a small check area has received an application of boron at a rate of 20 pounds per acre. Elbert Graham, farm owner and one of the district supervisors, is standing in the foreground of the picture. AR-D25-70.

Photograph of a volunteer crop of crimson clover which has reproduced itself by volunteer seeding for a period of 5 consecutive years. This winter's legume crop has served as soil conserving and building the [?] winter legume. Disking has been about the only cultivation given this 12 acre red apple and peach orchard in the background where the crimson clover has volunteered red with the seeding made in the fall of 1943. Dewey Vaughn, farm operator, is shown examining some of the heads of crimson clover which the farm owner expects to harvest for the seed. The seed yield has been estimated at 300 pounds per acre or more for that part grown without small grain. AR-D25-71.

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.

Photograph of grass plantings nest to tree rows on the Station. Pictures taken to show one possible method of covering the exposed area commonly found adjacent to shelterbelts. Evidence of these photos may not be too conclusive since all the grass plantings are young, but the physical fact of establishment is illustrated. OK-8741.

Photograph of wind and water erosion control on peanut field. Contour strip crops of soy beans (4 rows wide) with 8 rows of peanuts in intervals. Peanuts have been dug and lay in shanks for curing. TX-41, 844.

Photograph of a combine used for harvesting seed from a combination planting of winter oats and hairy vetch. The back of the photograph proclaims, "Combination planting of winter oats and hairy vetch being harvested for seed with combine."

Photograph of Alfred Austin farm showing a pure bred herd of Jersey dairy cattle with black-faced sheep grazing on posture composed of rye grass, hop clover, lespedeza, white clover, and Landino clover carrying 2 ½ animal units per acre at present. This pasture averages over 1 animal throughout the season. Mr. Austin has 21 head of Jersey cows with 22 heifers and 95 head of sheep including lambs. AR-D25-69.
