Cover seed 1" deep _ Annual ryegross 1 lb. 40 lbs. Cover seed 1/4 "deep* + Not necessary where mulch is applied. Seedbed Preparation Apply lime to raise the pH to the level needed for species being seeded. Apply 23 pounds of 12 -12 -12 analysis fertilizer (or equivalent) per 1000 sq. ft. (approximately 1000 pounds per acre) or fertilize according to test. Application of 150 lbs. of ammonium nitrate on areas low in organic matter and fertility will greatly enhance vegetative growth. Work the fertilizer and lime into the soil to a depth of 2 -3 inches with a harrow, disk or rake operated across the slope as much as possible. Seeding Select a seed mixture based on projected use of the area (Figure 5-2), while considering best seeding dates. See Figure 5 -3 this sheet. If toler- ances are a problem, such as salt tolerance of seedings adjacent to streets and highways, see Figure 5 -4 this sheet before final selection. Mulch Rate Mulch is to be applied at 2,000 to 3,000 pounds per acre in areas not covered by erosion control blanketing. Mulch must be anchored using a mulch anchoring tool or form disk with dull, serrated, straight set blades, or bulldozer cleats driven up and down slope.
