Photograph of individual plants of Sorghum Almum, a new drought-resistant, warm-season, perennial, tall and luxuriant bunch grass under observation by the Soil Conservation Service [SCS]. The plant being shown by Hervie E. Skelley and son, Gomer, came from one seed planted 2 1/2 months previously (on June 15, 1956) with less than 3 inches of rainfall. Single plants have up to 53 stalks in this field. OK-374-2.

Photograph of a single plant of Sorghum Almum, a perennial, warm season, drought resistant grass being introduced into OK. The grass was planted on June 15, 1956. Two months and 14 days later, after a very dry growing season, the seed stalks reached 7 feet in height and developed a bunch more than a foot wide at the bottom. New shoots are being put out continually. The Soil Conservation Service [SCS] is watching the planting to see if the grass is acclimated to western OK. OK-373-8.

(center) and grandson, Gomer Skelley (left) in a field of Sorghum Almum, a new drought-resistant, warm seson perrenial, tall bunchgrass being tried in western Oklahoma, under the observation of the Soil Conservation Service [SCS] technicians. Plantings are 2.5 months old with less than 3 inches of rainfall since initial planting. OK-373-11.

Photograph of sorghum almum, a newly-introduced perennial grass from New Zealand in one of two trial field plantings in Okahoma. Soil Conservation Service [SCS] field men are studying the grass to determine its suitability in semi-arid western Oklahoma. In the picture, L to R: Gomer Skelley, Hervie E. Skelley and R.E. Skelley, a 3 generation partnership. OK-373-6.

Photograph of the condition of two soil samples held by two UNIDENTIFED people. The back of the photograph proclaims, "Soil (Condition). Two samples of soil showing the deterioration in the one on the left due to 40 years of soil depleting cropping system as contrasted to the good soil sample on the right taken where a good grass rotation has been practiced. Note color and structure of samples."

Photograph of soil (noting condition). Plow pan is completely separated from tilled soil above and subsoil below. Pan is approximately 1 inch thick on soil unit 6. This condition was formed by 40 years of cropping to soil depleting crops. Sample was taken from a field where poor land use practices were followed. OK-329-12.

Photograph of two soil samples. The left shows deterioration due to 40 years of soil depleting cropping systems. The right by contrast shows a good soil sample where good grass rotation have been practiced. Note the color and the structure of the samples. OK-328-4.

Photograph of soil (noting condition). Profile of soil under poor land treatment (left) in contrast with soil under excellent cropping system (right). The poor treatment of above shows poor structure and low organic matter. The good treatment shows good structure and very high organic matter. OK-329-1.
