Photograph of a six year old Switchgrass in bloom. Note bare ground near clump where sand Lovegrass has been eliminated.

Photograph of land seeded to sand Lovegrass in 1945 and over seeded to bluestem mixture in 1950. Note elimination of sand Lovegrass in competition with other grasses.

Photograph of some excellent specimens of bluestem. Sand bluestem on the left and little bluestem on right. Note sand Lovegrass adjacent. Pasture was grazed all during 1955 but not heavily. Good vigor of grass in 1956 at watering place. Bluestem plants six years old.

Photograph of flood prevention structure. Core drill drilling 12" dia. holes thru 18'' corr. sh. mt. pipe set in the working platform. Holes were drilled 40' deep to be used in forming concrete piles and a spread footing.

Photograph of Carey silt loam profile. Note the compound columnar structure and the accumulation of caliche. The A1 horizon is about 12 inches thick, the B2 and B3 are about 2 ½ feet thick and the C ca [ca = pedogenic carbonates = carbonic acids that can that modify soil constituents] horizon extend below this. Entire picture covers 6½ feet of depth, typical of much of Carey soils in Harper County, transported by alluvial-colluvial forces from nearby hills and a weak B horizon has formed in places. Some soils are moderately permeable. OK-304-4.

Photograph of crop residue utilization. Excellent wheat on 70 soil.** Mr. Jude Matli, as SCD Cooperator, manages his crop residue to prevent sol loss by wind and water erosion by leaving a maximum amount of straw on the surface. He uses a combination of methods to control weeds and prepare a seedbed based on conditions of flexible tillage. His soil management program also includes a legume of vetch, sweetclover or alfalfa. OK-279-8. ** 70 soil. Unclear on the term. Perhaps referring to a 70/30 soil mix (= 70% topsoil plus 30% composting materials) or a heads or tillage per square foot number (https://extension.okstate.edu/fact-sheets/estimating-wheat-grain-yield-potential-2.html)

Photograph of native grass planting. This 7-acre seeding of Caucasian bluestem was planted in rows in 1951 on soil IV-12. Mr. Graden Teeter, shown, is a Soil Conservation District [SCD] supervisor. His use of this seedling has been consistent with good management practices. He has used it for a seed increase plot and for winter grazing. Note volunteer seedlings covering the areas between the rows. OK-298-1.

Photograph of upland alfalfa for soil management, William Widnay farm. Earl Judge (right) discusses the advantage of alfalfa on upland for soil building and cover. Mr. Widney uses alfalfa in his conservation crop rotation. This was seeded in the fall of 1952. For a nurse crop, ½ bushel of wheat per acre cross-drilled in wide spaced rows (every other row drilled). Wheat made 20 bushels per acre. Utilization of alfalfa has been spring hay crop, seed crop in the summer, and fall pasture. He has another planting of alfalfa and plans to plow this one up in the fall. His plans are for the alfalfa to be in a 3-year rotation. He has been a soil conservation district cooperator since 1948. OK-279-10.

Photograph of southland brome grass. Southland brome grass was planted on the Otto Cox farm near Lenapah, OK. Planted in the fall of 1951 following three years of hairy vetch. This grass is used as a cool season supplemental grazing grass and for seed production. Milton T. Gault, Soil Conservation Service (SCS), is examing the root system of the grass. OK-280-2.

His use of this seeding has been consistent with good management practices. He has no use for a seed increase plot and for winter grazing. Note volunteer seedlings covering the area between the rows. OK-298-1.

Photograph of two UNIDENTIFIED men standing in a field and looking at a sample of rye and vetch planted in the fall of 1955. A house or barn and a small building are directly behind the field and trees in photograph. The back of the photograph proclaims, "Rye and vetch planted in the fall of 1955. It was seeded at the rate of 1 bushel of rye and 30 pounds of vetch per acre and fertilized with 200 pounds of 10-20-10 per acre. Field was grazed by 30 head of milk cows in a grazing rotation with other pastures. Cows were removed on the 15 of March 1956 and the vetch and rye will be cut for silage. This field has been planted to vetch and rye for the past three years. Two tons of lime and 500 pounds of Rock Phosphate per acre were applied in 1949 according to soil test and crop needs."

Photograph of native grasses, Nowata, Oklahoma. The area on the left was seeded to a mixture of native bluestem grasses in the spring of 1949. It was seeded with one-row cotton planter using approximately 25 pounds of seed per acre. Native grasses were harvested in 1950 and every year since, averaging one ton of hay per acre annually. Area on the right is a virgin native grass meadow. The use of these climax grasses in this area was recommended by the Soil Conservation Service [SCS]. OK-280-1.

He uses a combination of methods to control weeds and prepare a seedbed based on conditions or flexible tillage.
