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. 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.

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.
