Photograph of Washita watershed, damage to front slope of Site 26 Wildhorse Creek Watershed. Dam runs almost due east and west. Part of slope was rip-rapped with rock from spillway but rock lacked about 6 feet being high enough to prevent this damage. SCS plans to repair this damage.

Photograph of Field # 2, Series 7. Milo [i.e., sorghum] residues from plantings made on 5-11-67. These rows were fertilized with 200 pounds per year of 10-20-10 fertilizer (1st 4 rows left to right) and 400 pounds per year for the next two rows and 200 pounds per year for the next two rows. These rows were side-dressed with 50 pounds of 33-0-0 in 6-67 on all of two rows and two rows half way. On 3-25-68 a native grass mixture (Vinita harvest) was interseeded, hand broadcast and hand-raked to cover. The east half of these rows were broadcast fertilized with 200 pounds of 33-0-0 per year and the west half with 200 pounds of 10-20-10 per year. OK-3013-12.

Photograph of Field # 2, Series 6. Broomcorn [i.e., Sorghum bicolor] residues from plantings made on 5-11-67. These rows were fertilized with 200 pounds per year of 10-20-10 fertilizer (1st 4 rows left to right) and 400 pounds per year for the next two rows and 200 pounds per year for the next two rows.

Photograph of Field # 9 with hay mulch applied on 4-1-68. This 0.8 acre area was first seeded to a mixture of native grasses assembled by the Manhattan Plant Materials Center. It was then mulched with prairie hay at 3 tons per acre. This was anchored with an IMCO disc treader (mulch tiller) pulled from a farm row tractor. Note the water standing where tractor tires force the parched water table to the surface. 250 pound 10-20-10 fertilizer top-dressed immediately after mulching. OK-3013-16.

Photograph of Field # 2, Series 10. Sumac residues from plantings made on 5-11-67. These rows were fertilized with 200 pounds per year of 10-20-10 fertilizer (1st 4 rows left to right) and 400 pounds per year for the next two rows and 200 pounds per year for the next two rows.

Photograph of a view of the IMCO mulch tiller manufactured by the Independent Manufacturing Company, Neodesha, Kansas, as used on the Eagle-Picher Slimes Pond hay mulching operation. Note the iron which weighs some 60 to 70 pounds, each. These served to put pressure on treader adequate to press hay into sand. Three tons of hay mulch per year were applied and anchored following the planting of a native grass seed mixture prepared by the Soil Conservation Service Plant Materials Center, Manhattan, Kansas. OK-3013-6.

Photograph of Gowan Clay Loam, small bottom showing the size of many of these areas of soil. Pecan tree is typical.

Photograph of grain sorghum on Yahola fine sandy loam, Class I bottomland soil. For use in Jefferson County Soil Conservation Report.

Photograph of "Chunk" Reid spot-seeding and pitting native grasses. Note the excellent job of grass management.

Photograph of grass land near Ryan, Oklahoma. A typical landscape. Deep sand range site, fair condition, Minco fine sandy loam soil type. Principal forage species are little bluestem, sideoats grama, tall dropseed, Scribner’s panicum. Non forage plants are sandage, gaura, spp. [Latin = species pluralis: “multiple species”], doze-daisy; yucca-woody species are sand plum and prickly ash. OK-1466-1.

Photograph of grasses. A field that has been out of cultivation for 10 years. No grass was planted but was seeded naturally [i.e., letting the grass grow enough to germinate flowers that produce the seeds or where it produces side shoots either above or below the soil]. In good condition. The pasture has been well-managed. Loamy Prairie site. OK-1173-4.

Photograph of Bob Deevers, opr. , inspecting a waterway that was constructed and sodded to Bermuda grass in 1960. Terraces were constructed after wheat harvest in 1960 to outlet into this waterway.

Photograph of the east view of site where water impoundment plots will be constucted to study inundation tolerance of selected vegetation as related to watershed treatment. Location-southesat of Lake Chickasha; Sec. 22, R9W, T8N, Soil-Reddish Prairie, virgin rangeland, Noble loam, slope 7%, erosion 1, Class IV. This study is in response to SCS research needs. Work is under the supervision of Edd D. Rhoades, Agricultural Engineer, ARS-SWC.
