Photograph of a field, which the contour pasture ridges have become vegetated. An UNIDENTIFIED town, possibly Ninnekah, is visible in the background. The back of the photograph proclaims, “Contour pasture ridges which have become well vegetated.”

Photograph of a heavily timbered area that was in poor range condition. Early June 1955 tow pounds of Kuron (propionic acid) per acre was applied by aero plane. All vegetative growth of shrubs and trees was controlled on 90 % of the shrubs and trees. A definitive percentage of tree kill could not be determined at this time but a tremendous growth of primarily little bluestem can be observed even directly underneath the trees. An excellent seed crop was produced by this area which was completely deferred from grazing during 1955. Soil Unit 12-RP is the prevailing soil type.

Photograph of a portion of the mile long supply ditch for the Neville irrigation system supplying water for 200 acres with the pump supplyiing 4,000 gllons of water per minute, 120 2-inch cyphering tubes used per setting, watering approximately 8 acres per setting.

Photograph of a portion of a 200-acre field level bordered in the Washita River bottom. This is the first water after leveling and corrugating. Winter oats were seeded and with Nitrogen fertilizer applied, yeilded 80 bushels per acre in 1953. Seeded to alfalfa in 1953 and with 400 lbs of 0-20-0 per acre produced 7 tons per acre. Water supply comes from the Washita River from a unit supplying 4,000 gallons per minute.

Photograph of terrace construction. Striking off the back slopes of a channel type terrace built entirely with a bulldozer. See OK-190-12 for the first pass made with the bulldozer in starting the construction. OK-190-10.

Photograph of a bulldozer striking out the last pass on a channel-type terrace constructed entirely with bulldozer equipment. See OK-190-10 for the completed terraces and OK-190-12 for the starting of the terrace. The terrace spills directly into a meadow strip shaped and seeded to King Ranch [KR] Bluestem in March, 1952. OK-190-11.

Photograph of Howard Nix combining native bluestem mixture on the farm of Alva Tims. Proper range management and rotation grazing permitted the harvest of 1500 pounds of bluestem mixture from approximately 35 acres.

Photograph of Claud Leonard (left), Work Unit Conservationist, Rush Springs, Okla. And Howard Nix combine operator, examine some of the native bluestem mixture harvested from this area. 1500 pounds of seed were harvested from approximately 35 acres.

Photograph of the "Effect of three years on contour pasture ridges. Grass growth is markedly better immediately above and below the ridges." A few houses, barns, and other buildings are in the background. This photograph is a follow-up to the photo listed as 9-322.

Photograph of a "Large area of contour furrowed pasture. Furrows are built 1 ½ years ago."

Photograph of an UNIDENTIFED man standing in a gully caused by unprotected terrace outlet. The back of the photograph proclaims, "Gully along fence row is the result of unprotected terrace outlet channel and will be sloped and sodded to Bermuda for erosion control. Terraces will be extended across channel to divert all runoff out of gully & into adjoining pasture and the fence will be relocated."

Photograph of Claude Leonard, Work Unit Conservationist, [WUC] of Rush springs, Oklahoma, observing excellent growth of Little Bluestem. This heavily timbered area was in poor range condition. In early June 1955, two pounds of Kuron (propionic acid) per acre was applied by aeroplane. All vegetative growth of shrubs and trees was controlled on 90% of the shrubs and trees. A definite percwentage of tree kill could not be determined at this time but a tremendous growth of primarily Little Bluestem can be observed even directly underneath the trees. An excellent seed crop was produced by this area which was completely deffered from grazing during 1955. For the "before" treatment piucture refer to OK-12-1. Soil Unit 12-RP is the prevalent soil type. OK-190-5.

Photograph of Claud Leonard, Work Unit Conservationist [WUC], Rush Springs, Oklahoma, observing the dead timber from the effects of spray material. This heavily timbered area was in poor range condition. In early June, 1955, two pounds of Kuron (Propionic acid) per acre was applied by airplane reducing the vegetative growth of shrubs and trees by 90%. A definite percentage of tree kill could not be determined at this time but a tremendous growth of primarily Little Bluestem can be observed even directly underneath the trees. An excellent seed crop was produced in this area which was completely deferred from grazing during 1955. For the “before” treatment picture, refer to OK-12-1.

Photograph of the first push in the beginning of construction of a channel-type terrace with bulldozer equipment. Note the white flag just in front of the bulldozer marking the center for the completed channel. For the completed terrace, see OK-190-10 and later pictures for the other steps in the construction of channel type terraces with bulldozer equipment. OK-190-12.

Photograph of Houston Hicks, combining native grass from the Alva Tims farm. Rotation grazing and conservation ranching had permitted this grass to make an excellent seed crop in 1955. 58 pounds of good seed per acre, principally little bluestem and Indiangrass were harvested.

Photograph of Plot 3 of 6, wheer ARS is studying the inundation tolerance of selected grass species. This plot was flooded two times during 1961 each for a duration of 20 days. Mr. Robert W. Graves, SCS, Rush Springs, Okla., is standing at the 5.0' depth. Work is under the supervision of Edd. D. Rhoades, Agricultural Engineer, ARS. Project is in response to SCS research needs. Flooding dates: 3/22/61 to 4/11/61 and 5/2/61 to 5/22/61.

Photograph of water impoundment plot No. 4 (one of six) used to study the inundation tolerance of selected grass species. This plot was flooded only one time during 1961 for a period of 20 days. Work is under the supervision of Edd D. Rhoades, Agricultural Engineer, ARWS-SWC. Project is in response to SCS research needs. Flooding date 5/1-5/21/61.

Photograph of “Masonry arch drop at V-point of two gullies and also serves as drop in terrace outlet disposal system. Man at right is standing in newly build outlet channel. Man at left is standing in gully which will by silted. To be followed with later pictures.” Both men in this picture are UNIDENTIFED.
