Photograph of an aerial shot of a large gully on a tributary of Ionine Creek and the surrounding area. A road runs parallel to the gully. The back of the photograph proclaims, “Large gully on tributary of Ionine Creek. 70 ft. deep and advancing 70 ft. per year. Detention reservoir below this reservoir would require 40 inches of sediment storage for 50 years without sediment control measures.”

Photograph of J. A. Killough in fourth of a series: How to take a composite surface soil sample. After you have taken a thin slice of soil from the hole, take a core about a half inch wide from the center of the slice and place in a clean bucket. Repeat for each spot selected within the field or area to be sampled.

Photograph of J. A. Killough in second of a series: How to take a composite surface soil sample. At each spot the plant growth, trash or mulch is cleared from the ground where the hole is to be dug.

Photograph of J. A. Killough in fifth of a series; How to take a compostie surface soil sample. After soil is taken from each spot selected from the area to be treated it is thoroughly mixed. Two or three hand fulls of this mixed sample is placed in a clean bag and tagged with required information. Sample should not be mixed from different areas to be treated.

Photograph of J. A. Killough in third of a series: How to take a composite surface soil sample. Dig hole depth of surface soil through plow depth. Then take a thin slice of soil (1/2" to 3/4" thick) from the hole. This is repeated from each spot selected within the field or area to be sampled.

Photograph of soil sampling. Third in a series: How to take a composite surface soil sample. Dig hole [ranging from the] depth of the surface soil through plow depth. Then take a thin slice of soil (1/2 to 3/4 inches thick) from the hole. This is repeated from each spot selected within the field area to be sampled (See OK-2-4, 2-5, 2-9 and 2-11).

Photograph of soil sampling. First in a series: How to take a composite surface soil sample. A farmer is planning to take his soil sample. Necessary equipment includes a sharpshooter or spade and a clean bucket. [a "sharpshooter" here is a nickname refering to a tile spade that can be carried with the end held in one hand as the remaining length juts diagonally into the air as supported on the shoulder--in the same way a sharpshooter can carry a rifle]. (And see OK-2-5, 2-6, 2-9 and 2-11). This is photo OK-2-4.

Photograph of overgrazing. Deep Prairie Site, poor condition class. Prolonged overuse during 5 subnormal annual rainfalls has brought about vegetation composition decline from a bluestem mixture to an almost pure stand of Buffalo grass. “Close” degree of utilization as determined by the Soil Conservation Service [SCS]. OK-423-6.

Photograph of B. C. Bush, State Aid, discuss grass seeding on conservation reserve acreage with Sudan grass cover crop, with farmers Howard Warren and Clifford Hitchings. The photograph does not identify the left to right positions of Bush, Warren, and Hitchings. The back of the photograph proclaims, "B. C. Bush, State Aid, discuss grass seeding on conservation reserve acreage with Sudan grass cover crop, with farmers Howard Warren and Clifford Hitchings. Drills are two 9 hole and two 8 hole 12" spaced owned by Cimarron County SCD. The drills are hooked up on three drill hitches, which cover 34 feet each time through the field. Farmers are averaging 130 acres per day sided by a mixture of side oats [sic] grama, blue grama, and sand lovegrass. The field's soil is Dalhart-Mansker loam (7-B)."
