Photograph of Slimes Pond, Eagle-Pichers Mine, Picher, Oklahoma. A follow up on Photo No. OK-3013-7. A test to determine whether rye can be grown for cover crop and whether grass can be established in growing rye. View from the southeast corner of Field No. 7 — 3.1 acres. Rye seeded on 9-25-67. Fertilized 250 pounds of 10-20-10 fertilizer at planting time. Top dressed 250 pounds 33-0-0 February 1968. Since native grass drill was not available, field was roto-tilled and native grass was overseeded with an E-Z Flow spreader on March 26, 1968. Rye showed considerable chlorosis at that time and stand was also weakened by tillage. See foreground. OK-3118-5.
