Photograph of the H.C. Wright Farm with a John Bean power sprayer equipped to make basal bark applications on brush and trees. The person shown is Harry M. Elwell, Research Agronomist for Field Crop Research, USDA, located at the Red Plains Conservation Experiment Station, Guthrie, Oklahoma. OK-11-10.

Photograph of basal-bark application using 2¾ gallon of a low-volatile 2-4-5T ester (4 pounds acid per gallon of material used) in 100 gallons of diesel oil. The spray is applied so as to completely encircle and wet the lower 12 inches of each plant even to the point of run-off onto the soil. The equipment used was a John Bean-powered sprayer. The brush and trees were blackjack, post and white oak, hickory, elm, persimmon and dogwood. OK-11-8.

Photograph of a typical view of brush and tree cover often occupying a site that will produce good grass with proper herbicidal treatment. OK-11-9.

Photograph of a mule. This beast of burden, although scarce in most sections of Oklahoma, still figures in the economy of the hill country. In the application of a conservation program, a farm planner often must change his thinking from a tractor-operated farm to one in which this animal and his offspring will be used. OK-139-9.

Photograph of basal-bark application using 2-3/4 gallons of a low volatile 2-4-5-T herbicide ester (4 pounds acid per gallon of material used) in 100 gallons of diesel oil. The spray is being applied so as to completely encircle and wet to the point of creating run-off onto the soil the lower 12 inches of each plant. The equipment used was a John Bean power sprayer. The brush and trees were blackjack, post and white oak, hickory, elm, persimmon and dogwood.

Photograph of Dr. J.O. Lynd (left), Agronomy Department, Oklahoma A&M College [i.e., Oklahoma State University] and George N. Lowe, Work Unit Conservationist {WUC], discussing 8 weeks growth of Bermuda grass from seed. This field was native grass in the stand. A clean, firm seedbed was prepared by plowing, discing and harrowing, then with the roots planted with an automatic planter followed by section harrow. 100 pounds of 10-20-10 fertilizer was applied with the roots. Roots were planted in May and June. On July 8, 9 and 10, Bermuda grass seed was planted at the rate of 2 pounds per acre, with an EZ-Flow plow, using attachment and press whells. The field was not pastured prior to making the picture on 9-1-1955. OK-139-7.

Photograph of Nolan Denton, WUC, discusses soil management program with Fred Metzger for Soil Unit 8H BO, Class I. Early hybrid corn following soybeans for seed. Rotation includes alfalfa, corn, soybeans, cotton, wheat and vetch. It looked like up to a 50 to 60 bushel yield at hard roasting ear stage after a very dry season. Metzger is a strong believer in soil improving crops. OK-70-9.

Photograph of Nolan Denton, Work Unit Conservationist [WUC], Muskogee, Oklahoma, checking “tall corn” on Class I land, Soil Unit 4 BO. This corn following 2 years of fescues, has soil in excellent physical condition. OK-70-10.
