Recommendations:

Recommended pH:5.5 to 6.5. If the pH is less than 5.5, see Lime Table C and the soil depth adjustment table that immediately follows the lime tables.
Nitrogen:2-4 pounds nitrogen (N) per 1000 square feet, depending on color and growth desired.
Magnesium:

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

S47.

For establishment, incorporate 10 pounds of 10-10-10 per 1000 square feet into the top 4 to 6 inches of soil prior to seeding, sprigging, or sodding. Then apply 3 pounds of 34-0-0 or 2 pounds of 46-0-0 per 1000 square feet in mid-summer. Follow this fertilization program for the first year only, then use the maintenance fertilization program for the next 2 to 3 years. Retest 2 to 3 years after establishment.

For maintenance, apply 10 pounds of 16-4-8 per 1000 square feet after spring green-up and again in mid-summer. The last fertilizer application should be made prior to September 1.

Fact Sheet:

Clippings do not contribute to thatch under proper management and thus, do not need to be removed. If they are removed, increase the fertilizer application rate by 30%.

CAUTION: Water lawn thoroughly immediately after applying fertilizer. Do not apply fertilizer when grass is wet.

Maintain minimal nitrogen fertility rates, over fertilization can lead to development of thatch.

These recommendations are for non-salt affected sites. In the case of salt affected soils, contact local County Extension Agent or turfgrass specialist for additional assistance.
