Photograph of "Gullying, sheet erosion, and siltation resulting from 10 inch rain on Grant silt loam, 3-5% slopes. Land was clean tilled." A house is located in the background on top of the hill.

Photograph of a Brillion Seeder used to plant weeping lovegrass strip on 7x AB Pratt, Fine Sandy Loam after soil was prepared with a rod weeder and chisel type machine. The back of the photograph proclaims, "Wind Strip & Rotation Hay and Pasture. Pasture strip on 7x AB Pratt, Fine Sandy Loam showing Brillion Seeder which was used to plant the weeping lovegrass strip after soil was prepared with a rod weeder and chisel type machine."

Photograph of various cropping systems at the Cherokee Experiment Station. The back of the photograph proclaims, "Cropping systems. (A). Caddo Switchgrass 3 year, rotated with 3 years wheat, the wheat yield average 39.9 bu. per acre. (B) Compared to 3 years alfalfa rotated with 3 year wheat, the wheat yields averaged 46.6 bu. per acre. (C) Continuous wheat No. N/A equals 33.5 by per ac. (D). Continuous wheat 40 lb. N/A equals 46.6 bu. per acre. Three years Caddo Switch is only beginning to have its effect on soil improvement."

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."

Photograph of an UNIDENTIFED man standing in a contoured field on the Nelms Avant farm. This field is currently growing cowpeas and milo in alternating rows. The back of the photograph proclaims, "This is a field farmed on the contour to prevent water from running off rapidly and causing damage by erosion. In this particular field there are two separate crops, cowpeas and milo maize. These are planted in alternate rows."

Photograph of the Cherokee Experiment Station, Cherokee, OK. HQ shown in the background. More than 300 farmers and agricultural workers at the Field day, May 24 (1962). Two treatments are applied to wheat as shown in the foreground. Average yields of wheat "cleaned" tilled continuous wheat without nitrogen is 41.2 bushels per acre. Stubble mulched continuous wheat with 40 pounds. Nitrogen is 45.4 bushels per acre. OK-1724-1.

Photograph of a flood, Waggoner farm, near Driftwood, OK. Looking across the creel channel and adjacent overflowed land from bridge approach on OK Hwy 58 on the morning after receiving a 4 inch rain. Considerable damage was done to the ripening wheat crop. Farmers in this watershed have made early planning steps for instituting a watershed program on this creek through the Soil Conservation Service. OK-1724-8

Photograph of flooding. Looking south on the highway toward Driftwood Creek (channel is among the distant trees) on the morning after receiving 4 inches of rain. Considerable damage was done to ripening wheat crop. Farmers in this watershed have made early planning steps for initiating a watershed program on this creek through the Soil Conservation Service. OK-1724-10.

Photograph of Cecil Reinhart kneeling in a four acre strip of weeping lovegrass used as wind-strip and rotation hay and pasture on 7x AB Pratt fine sandy loam soil. The back of the photograph proclaims, "Rotation Hay and Pasture. 4 acre strip of weeping lovegrass used as wind-strip and rotation hay and pasture on 7x AB Pratt fine sandy loam soil. Reinhart harvests seed and pastures these strips in the winter with small grain and vetch. Seed harvested 6/20/59 yielded 800 lb. seed on the 4 acres. After 5 years the strips are plowed up and other strips are seeded to control wind erosion."

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 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."
