Photograph of plastic irrigation pipe being installed. This pipe will be deep enough to allow farming over it. It will have risers at proper intervals to do a complete irrigation job on this farm. Pipe is installed at $1. 75 per foot including risers and will carry from 500 to 600 gallons of water per minute. Test pressure of 80 lbs. can be carried in pipe. Plastic pipe makes the system permanent. Class I on 0 to 1% slope, Soil Unit 2-RR.

Photograph of stream bank cutting. Temporary stream bank erosion control measure. Bridge is located in a bend in the river and each time the water rises some more bank is eaten away near the end of the bridge. These trees are held in place by a cable and keep the water away from the raw bnk of the river. The section of bank from the man in photograph to the present location of bank was eroded away in one year.

Photograph of re-seeded native pastures. Native grass died during drought of 1955 – 1956. Field was disc-plowed and seeded to a mixture of buffalo, blue grama and Sideoats grama in February 1957. Ward Perryman in photo. Soil Conservation Service [SCS] recommended reseeding on 320 [?] acres of this farm. OK-901-2.

Photograph of Class I land untreated, closely drilled to oats. Large closely stacked shocks of grain indicate profitable yield. Due to long slope, the field will be terraced for water conservation. Less than 1% slope. Olustee, silty, clay loam. OK-8180.

Photograph of soil. Sample of soil, Unit 70. Showing plowman condition.

Photograph of a soil survey. Harmon stony loam. A very shallow to shallow soil developed on dolomitic limestone. Class VI land. Shallow Range site. OK-720-6.

Photograph of brush control, showing mesquite trees that have been deadened by pouring kerosene on the crowns. OK-93-5.

Photograph of a soil survey. While making the soil survey, Richard Graft, Soil Conservation Service [SCS] scientist, discovered a recently-formed gyp sink [= a sinkhole] in a gently sloping wheat field of Tillman clay loam soil. The gyp sink is approximately 30 feet deep and 15 feet wide. OK-720-12.

Photograph of stream bank erosion. Temporary stream bank erosion control measure of Cottonwood trees secured to stream bank by cables. This measure was setup to protect approach at west end of highway bridge.

Photograph of pumping equipment for irrigation system. This pump will be used to pump 500 to 600 gallons of water per minute into an underground irrigation system. This underground pipe is of 10" plastic and will be a permanent installation. Class I land on 0 to 1% slope, Soil Unit 2-RR.

Photograph of Jake Ringwald and Hubert Mobley, SCS Soil Scientists, peering into recently formed gyp sink hole, which is approximately 30 feet deep and 15 feet wide. The photograph does not identify the left to right positions of Ringwald or Mobley. The back of the photograph proclaims, "Jake Ringwald and Hubert Mobley, SCS Soil Scientists, peering into recently gormed [sic] gyp sink in a gentley [sic] sloping what field of Tillman clay loam soil. The hole is approximately 30 feet deep and 15 feet wide. See Ok-720-12 for inside of hole."

Photograph of sample of soil Unit 70, showing plowpan condition.

Photograph of a tanker metering 8-12-0 liquid fertilizer into irrigation water channel. The back of the photograph proclaims, "Irrigation-fertilization." Metering fertilizer into irrigation water in order to cut down on time and labor needed to do two jobs. The fertilizer is in liquid for and is gaged to the amount of water being used. The fertilizer is added to the water far enough ahead of where it will go on the land to insure complete mixing. The flow of water and fertilizer are regulated to get proper amount of fertilizer on each acre. Fertilizer is 8-12-0."
