Seedbed Preparation for Per manent Seedin 1. Test soil to determine pH and nutrient levels. (Contact you county SWCD or Cooperative Extension includin 'n c it informatio nce and soils for assistance office o 9 available testing n services.) 2. If soil pH is unsuitable for the species to be seeded, apply lime according to test recommendations. 3. Fertilize as recommended by the soil test. If testing was not done, consider applying 400 -600 lbs. /acre of 12 -12 -12 analysis, 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 a disk or rake operated across the slope.
