Type

The best fertilizer to apply after aerating the lawn in the fall is one that is high in nitrogen, such as 25-5-5. The next-best fertilizers are urea, 46-0-0, or ammonium sulfate, 18-0-0.
Rate
-
Use 6 lbs. of 25-5-5 per 1,000 square feet of lawn. If you use urea, apply 2 lbs. per 1,000 square feet. Apply ammonium sulfate at a rate of 5 lbs. per 1,000 square feet.

Considerations
-
Some areas of the country experience warm autumn weather. Try to aerate the lawn on a day when the temperature will remain below 80 degrees Fahrenheit, so that you don't run the risk of the fertilizer burning the lawn's roots.
