Recommendations:

Recommended pH:6.0 to 6.5. If the pH is less than 6.0, see Lime Table B and the soil depth adjustment table that immediately follows the lime tables.
Nitrogen:5-7 pounds nitrogen (N) per 1000 square feet. (The higher rates will be needed under irrigated conditions or if clippings are removed.)
Magnesium:

If soil test Mg level is low and lime is recommended, use dolomitic limestone.
