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 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 conservation crop rotation. Kochia weed and salt grass on salt area where it is very difficult to get crops started. The problem is this—getting the crops started. Volunteer kochia weed serves as a priority treatment to get a cover on the land. At certain stages cattle graze readily and it supplies a large amount of organic material when plowed down in a seed-bed preparation. OK-745-2.

Photograph of Noble blade stubble mulch tillage machine being used on Wheatland Exp. Station. This is the first operation by the 8 ft. blade cutting approximately 5 inches under the surface. It raised the slice of dirt slightly, but leaves the stubble and other residue in place.

Photograph of 7X-AB Pratt Fine Sandy Loam soil. Reinhart using a rod weeder fastened to a chisel type instrument. Chisels loosens soil and rod rotates in reverse which lifts all vegetation up from 4 inch depth. On tighter or more loamy soils this machine is used after one-waying for the second operation.

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 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."

Photograph of a plastic protector for a waterway. State soil Conservationist Earl Rowley and Dan Hamill. Work Unit Conservationist [WUC], Weatherford, Oklahoma, demonstrates a plastic cover that can be spread over a Bermuda grass waterway where the slope increase would be a hazard. Water can flow over the plastic preventing erosion. The Bermuda grass receives sunlight through the plastic. Soil moisture loss under the covered area is reduced to a minimum. OK-692-7.
