Materials and Rates of Application shall be as specified herein or as approved by the COR.

1.

Seed. Seed shall be certified to be the latest season's crop and shall be delivered in original sealed packages bearing the producer's guaranteed analysis for percent of seed mix and pure live seed.

Temporary seed and mulch will be applied as directed by the COR. Seed mixtures shall be proportional by weight as follows:

Seed Species to Use Between 3/1 and 5/15

Seed Species to Use Between 8/15 and 10/15

Weed seed shall not exceed 0.5% by weight of the total mixture. Seed mixture shall be applied at a rate of 5 pounds per 1,000 square feet or approximately 220 pounds per acre.

2.

Wood-Cellulose Fiber. Wood-cellulose fiber (hydro-mulch) shall be thoroughly mixed and applied at the rate of 1,500 pounds per acre to produce a homogeneous slurry.

3.

Fertilizer. A complete fertilizer with a formulation of 10-20-10 or 10-10-10 shall be applied at a rate of 600 pounds per acre. At least 40% of the nitrogen shall be in a slow release form.
