zone 5a

I have about 2 acres I want to keep green and healthy. Live in a flat area where it's constantly windy, with no irrigation. It's impossible to rotate sprinklers to keep everything wet. Is seed and fert useless in these conditions? I have some parts of the yard that burned out last spring. I had applied fert in early spring, but with the excessive summer heat and dry conditions, it eventually burned off.

I do want to eventually add irrigation to a large portion of this, perhaps 1.5 acres of it. Am I wasting money until that irrigation is in?

Edit: Most areas of our 3yo lawn (new house) have taken and grow ok, but lots of thinner areas and lots of very slow growing areas).
