Photograph of streambank erosion in continuously grazed pasture.

Photograph of a scalper or screener built at Woodward Nursery and used to separate large trash from seed material. The machine is operated by a small concentric [motor or engine?] having a stroke of about 3 inches and is powered by a small, electric motor. Hand harvested switch grass material is being screened. OK-8893.

Photograph of an important phase of Soil Conservation Service [SCS] regional operations which is the creation and development of needed conservation equipment. SCS technician Paul Browning (right) and DeBoy Wheatley put finishing touches on a SCS grass planter they designed and developed to do a 20 million acre Bermudagrass planting job in Region 4. Adjusting throw-out clutch between performance tests. OK-9702.

Photograph of pecan trees. These pecan tress were fertilized in 1956 using about 40 pounds of 10-20-10 fertilzer per tree. Fertilizer worked into the ground under trees. This year the crop promises to be very good. OK-559-6.

Photograph of a living herbarium at the State Fair of Oklahoma prepared by members and chapters of the Soil Conservation Society of America—the Central Oklahoma Chapter of Oklahoma City, Northeast Oklahoma Chapter of Claremore and the South Central Chapter of Ardmore in cooperation with the Oklahoma Seedmen Association and the State Fair Association. The exhibit is comprised of tall, mid- and short native grasses, with forbs and legumes common to central Oklahoma. Widespread interest was exhibited in this project. It is estimated that 15,000 to 20,000 people viewed the exhibit. It is planned that the exhibit will be permanent and will be used for identification purposes by such groups as garden clubs, 4-H and Future Farmers of America [FFA] clubs. Training of service personnel acted as guides, answering many questions pertinent to the widespread application of the soil conservation program in Oklahoma. OK-160-2.

Photograph of a combination seed huller, scarifier, cleaner and grader. This machine was operated at about 1200 rpm with a 3 to 5 horsepower gasoline motor and cleaned at the rate of 1000 pounds of cleaned seed per day. The loss in weight from unhulled, unscarified seed from the grain operator varied from 15% to 35% in weight where average loss was 25%. AR-D25-31.
