I've never heard that about the nitrogen and new sod. If anything, you may be able to use a little extra. By this time your sod should be established and basically a normal yard. 1 lb of nitrogen around Labor Day, and 1 lb late fall. Fall is the most important time to fertilize.

A soil test would tell you exactly what your ground needs.

With the 30-0-10, you would apply 3.3lbs per 1,000 sq. ft. I think the that fertilizer is a good option for you. 1x now and 1x in November.

Without seeing a soil test I would probably use a starter fertilizer. When sod is harvested it is stressful on the grass because you are cutting the roots. Providing all three of the macronutrients is going to ensure your sod has what it needs to regrow roots as well as promoting overall plant health.

Good point. I didn't notice the first go around that he hadn't done starter yet.
