Photograph of Basel-bark application, using 2 3/4 gallon of low volatile 2-4-5, T ester (4 lbs. acid per gallon material used) in 100 gallon of diesel oil. The spray being applied so as to completely encircle and wet the point of runoff onto the soil the lower 12 in. of each plant. Equipment used was a John Bean powered sprayer.

Photograph of Dr. J. Q. Lynd (left), Agronomy Department, Oklahoma A&M College, and Geo.N. Lowe, WWC, discussing 8 weeks growth of Bermuda Garss from seed. This field was native grass in the stand. A clean firm seedbed was prepared by plowing, disking and harrowing, then roots planted with automatic planter followed by section harrow. 100 lbs of 10-20-10 fertilizer applied with the roots. Roots wer planted in May and June. July 8, 9 and 10 Bermuda Grass seed wsas planted a the rate of 2 lbs. per acre with 100 lbs. of 10-20-10 fertilizer per acre, with an EZ-Flow, using attachment and press wheels. The field was not patured prior to making the picture.

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 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.
