1. A control where no mulch was applied to the tailing 2. Two tons/acre barley straw 3. Four tons/acre barley straw 4. One year seeding of rye, rototilled after maturity and then seeded with grasses 5. Two years seeding of rye rototilled after maturity prior to new seeding of rye and then seeded with grasses 6. Three years seeding of rye with every crop being rototilled before seeding with grasses after the third rye crop All the cereal 'rye plots were rototilled in the fall, and reseeded with grass or cereal rye again after snowmelt in the spring. The plot area was limed with Ca0 at the rate of 4 tons/acre (CaC03). Phosphate wars applied at the rate of 200 lb P205/acre (0-46-0) and potash was applied at 200 lb K20/acre (0-0-50). The lime, P, and K were mixed about 6 in. deep into the tailing with a rototiller in June 1976. After germination, nitrogen was broadcast at the rate of 100 lb N/acre (33-0-0). The control and the 2 and 4 tons/acre barley straw plots were seeded at the rate of 40 lb/acre with the Climax seed mixture. The three rye plots were seeded with cereal rye at the rate of 40 lb/acre. The rye was hand broadcast while the grass mixture was cyclone-seeded on 26 June 1976. After the lime (Ca0) was evenly distributed, the plots were rototilled twice about 6 in. deep, then the fertilizers (P205 and K20) were hand broadcast and the plots were rototilled again. The straw mulch was pread by hand as evenly as possible and then rototilled twice. On plots receiving 4 tons/acre straw mulch, the straw was spread in 2-ton increments and rototilled twice following each application. In addition to the above formal study, the area surrounding the plots was limed, fertilized, mulched with 2 tons/acre alfalfa hay and seeded with the Climax mixture at the same rate as the plots. About 20 <_pruce were transplanted in the soil area south of the plots. Six clumps of willows 14
