(Contact you county SWCD or Copperative Extension
office for assistance and soils |nlornnmt|mn including

2. If soil pH is unsuitable for the species to be
seeded, apply lime according to lest recommendations.
3. Fertilize as recommended by the soil test. if testing
was not done, consider applying 4-OO-8OO \bo./ocre of
12-12-12 ono|ya(a, or equivalent, fertilizer.
4. Till the soil to obtain a uniform seedbed, working
the fertilizer and lime into the soil 2-4 In. deep with
