Home My WebLink About07030006.5Seedbed 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) c. 1000 sq. ft. (approximately 1000 pounds per acre) or fertilize according •a test. Application of 150 lbs. of ammonium nitrate on areas low in orgc- c matter and fertility will greatly enhance vegetative growth. Wheat or Rye Work the fertilizer and lime into the soil to a depth of 2 -3 rches pats with a harrow, disk or rake operated across the slope as much as possible. Seeding Annual Ryegross 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.
