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 trial basis of healing gullies. Gully sloped with a bulldozer. Cost estimated at $80. 00 for bulldozer work, $10. 00 for roots and planter. Gully approximately 550 feet long, 20 to 30 feet wide and 10 to 15 feet deep.

Photograph of Ted Lehman, WJC, and Bill Storm, County Agent, examining an area treated for bindweed. Farmer applied Boroacu at the rate of 2300 pounds per acre in the Spring of 1953. A good kill was received except around the edges. Note size of area that has been out of production for three years. Bindweed is considered a serious problem in some areas of the High Plains. OK-138-4.

Photograph of land plowed in preparation for fall seeding. This operation of pulling a section harrow over land further reduces the size of clods, increasing the wind erosion hazards. Too much tillage is a problem that must be overcome in combatting wind erosion. Ted Lehman, WUC [Water Usage and Conservation] of Beaver, Oklahoma, says this is the "powder keg for blowing." OK-138-5.

Photograph of soil sampling. Fifth in a series: How to take a composite 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 (See OK-2-4, 2-5, 2-6 and 2-9). This is photo OK-2-11.

Photograph of a seven acre plot of land cleared with a bulldozer (John Holland) in June 1955, trees deposited in a windrow and offset by heavy disc plowing, 7500 pounds used to cut up underground roots into 12 to 14 inch segments. Depth of cut is approximately 12 inches. OK-97-8.

Photograph of Charley Connelly standing beside a diary herd. The Weeping Lovegrass pasture is 2 years old, per the date of the photo. The land itself was cleared 3 years prior with a bulldozer followed with a 7500 pound brush disc plow. OK-119-2.

Photograph of weed control. Ted Lehman, Work Unit Conservationist [WUC] and Bill Storm, County Agent, examine an area treated for bindweed. The farmer applied Borascu, a boron-oxygen based weed killer, at the rate of 2300 pounds per acre in the spring of 1953. A good kill resulted except around the edges. Note the size of the area that has been out of production for three years. Bindweed is considered a serious problem in some areas of the High Plains. OK-138-4.

Photograph of weed control. Ted Lehman, Work Unit Conservationist [WUC], Beaver, Oklahoma, examines regrowth of bindweed around the edges of an area treated with 2300 pounds of Borascu weed killer per acre in the spring of 1953. Bindweed is considered a serious problem in some areas of the High Plains. Persistent work is required to control this weed. Note the size of the area where grain sorghum is not growing. OK-138-3.
