Photograph of Cecil Drummond examining part of his 80-acre field seeded to native bluegrass mixture. The back of the photograph proclaims, “Cecil Drummond, father of Jack and Gant Drummond, examines portion of an 80-acre field seeded to native bluestem grass mixture on May 20, 1949. They find best results come from plowing, disking, harrowing and cultipacking, then planting. Seeding rate here was 12-14 pounds an acre. Weeds were clipped once in 1949 and once in 1950. Planting protected from grassing during growing seasons of 1949-50-51, grazed lightly during winter months. III - high good range condition.”

Photograph of J. M Teeter showing Jim Wyman, SCS, his irrigated pasture consisting of fescue orchardgrass, smooth brome, perennial ryegrass, and ladino clover. A larger herd of cattle is directly behind them. The photograph does not indicate left to right position of Teeter or Wyman. The back of the photograph proclaims, "J. M Teeter showing Jim Wyman, SCS, his irrigated pasture of fescue orchardgrass, smooth brome, perennial ryegrass, and ladino clover. The 8.6 acres were seeded in fall of 1949, then divided into 8 plots, each grazed 1 to 3 days and then rested 15 to 25 days. Pasture fertilized in early spring with 200# 16-20-0 and top dressed in summer with 100# ammonium nitrate. This has enabled Teeter to carry 25 head cows & calves during the summer."

Photograph of a Concentric-ring infiltrometer located at the Wheatland Conservation Experiment station located at Cherokee, Oklahoma. The back of the photograph proclaims, "Concentric-ring infiltrometer used on Experiment Station at Cherokee, Oklahoma. It was developed by Maurice B. Cox, Agri. Eng., working in cooperation with Louis E. Derr and W. Elmo Baumann, Soil Scientists. The water level in the rings are maintained at equal depth with the float chambers from discarded automobile carburetors. The rate of infiltration is recorded by a reconnaissance type recording rain gage as the water for the inner ring is siphoned from the filled rain gage bucket. Under field operation the rain gage should be closed to prevent wind movement from affecting the record on the chart. The barrel on the stand at the left holds approximately 20 gallons of water for the outer ring supply."

The back of the photograph proclaims, "Concentric-ring infiltrometer used on the Experiment station at Cherokee, Oklahoma. The rings are made of 14 gage iron. The strips are 8 inches wide. The diameter of the outer rings are 20 inches and that for the inner ring is 8 inches. An eight-inch center ring was used because the rain gage was standardized on an eight-inch top. A float chamber is placed in each of the center and inner rigns [sic] to maintain a uniform depth of water."

Photograph of Carson Millsap, SCS technician, studying ground cover in 4-acre field planted to native grass mixture in 1944. Grass in center foreground is King Ranch bluestem. It was established in native grass pasture from seed blown in from an adjoining 4-acre planting of KR> Grass in background is little bluestem. Shallow soil. Class VIII land.

Photograph of "Raymond Frey in 50-acre hillside field seeded to native grasses in mid-April, 1949. Land disked and harrowed ahead of grass planting. Frey says planting cost was less than $4 an acre, including labor, equipment and seed. Seeding rate around 10 lbs. an acre. Switchgrass predominating. This is same field shown in Okla-9935, Okla-9936, and Okla-9937. "Class VII land."

Photograph of George Eldred and Clay Wilson, SCS technician, studying grass growth in an 80-acre field seeded to native grass mixture in March 1950. People shown in photo go as followed from left to right: 1. Clay Wilson, SCS Technician, 2. George Eldred.” The back of the photograph proclaims, “Eldred, right, and Clay Wilson, SCS technician, studying grass growth in an 80-acre field seeded to native grass mixture in March, 1950. This picture was taken in a 9-acre area which was fertilized in April, 1951, with 150 lbs. of 5-10-5 an acre. Grass in this area has evidenced much better growth than grass in non-fertilized area. Grass has not been grazed. Eldred will use it for winter grazing after it becomes well established. 7RP-IV.”
