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.

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 a chat pile, the rock waste remains after lead and zinc have been extracted from hard rock, during the grinding and flotation system. Note the erosion of the pile. This material covers some 5,000 acres in Ottawa County. Wind and water move this finely ground rock to adjacent areas. OK-2769-11.

Photograph of the area around the Eagle-Pichers Mine, Picher, Oklahoma. Slimes Pond Evaluation of plantings in Commerce, Oklahoma. This is a view of the IMCO mulch tiller manufactured by the Independent Manufacturing Company, Neodasha, 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 the 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 the Eagle-Pichers Mine, near Commerce, Oklahoma. Here showing the effects of snow fences in checking wind erosion. The coaser silica material has drifted high in the snow fences creating a series of deep drifts of coarser particles. Note the absence of vegetation even though this is located in approximately a 44 inch ppt. [parts per trillion?] zone. OK-2769-5.

Photograph of the area around the Eagle-Pichers Mine, Picher, Oklahoma. Slimes Pond Evaluation of plantings in Commerce, Oklahoma. View facing northwest corner of planting area (Field no. 1). On March 17, 1967, 30 rows of grass and legume species were planted east-west. Note flagmarkers. Also in the background is a broadcast grass mixture plot. Prarie hay mulch at the rate of 3 tons per acre was hand spread over the whole area immediately after planting and anchored with a tandem disc. seedbed was compacted with the rubber-tired tractor after mulching. Snow fences are to protect study area from sand drifting. OK-2768-6.

Photograph of the area around the Eagle-Pichers Mine, Picher, Oklahoma. Slimes Pond Evaluation of plantings in Commerce, Oklahoma. View facing north showing eastern two-thirds and a glimpse of the northwestern portion of the planting area. Snow fences are for wind erosion and sand drift protection. In right foreground, are tree rows without mulch. Right background shows tree rows prairie hay mulched (3 tons per acre), hand-anchored. Tree species include cedar, button bush, sycamore, cottonwood, black locust, sand bar willow and Russian olive. In the left foreground are two plantings of grass selections followed by prairie hay mulch anchored with tandem discs and the seedbed compacted with a rubber-tired tractor. OK-2768-1.

Photograph of the area around the Eagle-Pichers Mine, Picher, Oklahoma. Slimes Pond Evaluation of plantings in Commerce, Oklahoma. View facing north-north central portion of planting area (Field no. 2). Cover crop plantings made and to be planted are to determine whether cover can be grown for eventual parennial vegetation plantings. Field borders are prairie hay mulched (3 tons per acre) and anchored with tandem discs. The tallest vegetation row is rye planted on 09-29-1966 and fertilized with 400 pounds per acre of 10-20-10 fertilizer. It was top dressed on 03-26-1967 with 50 pounds of nitrogen per acre. Summer cover crops are to be planted in the north portion of this filed. OK-2768-7.

Photograph of the area around the Eagle-Pichers Mine, Picher, Oklahoma. Slimes Pond Evaluation of plantings in Commerce, Oklahoma. View facing east along south portion of planting area (Field no. 4).

Photograph of the area around the Eagle-Pichers Mine, Picher, Oklahoma. Slimes Pond Evaluation of plantings in Commerce, Oklahoma. Filed 6 of field trial on slimes pond. This field consists of unmulched woody species of plantings. Note the seeding growth at this date. Trees received no fertilizer. OK-2768-14.

Photograph of the area around the Eagle-Pichers Mine, Picher, Oklahoma. Slimes Pond Evaluation of plantings in Commerce, Oklahoma. Grass seedlings were mulched with prairie hay that was hand spread following planting at the rate of 3 tons per acre and anchored with a tandem disc from March 15 - 17, 1967. This shows an adequate mulch cover, but demonstrates by the amount of loose hay on the surface that the tandem disc did not properly anchor this mulch. OK-2767-4.

Photograph of the area around the Eagle-Pichers Mine, Picher, Oklahoma. Slimes Pond Evaluation of plantings in Commerce, Oklahoma. View facing east showing the southeast section of area. In the foreground are rows of sod-planted grasses. From right to left are rows of switchgrass, broomsedge, bluestem, American beachgrass and then one row divided among three grasses--blowout grass, plumegrass and giant reed. In the background are tree plantings (Field no. 6) unmulched with a mulch border next to snow fences. OK-2768-16.

Photograph of the area around the Eagle-Pichers Mine, Picher, Oklahoma, here showing the drift effects of wind erosion from slime ponds. Drifts of silicas.
