Caring for grass at stadium

I think the key to your question is the condition of the soil on your fields. If they have been bare long enough for you to lose your good topsoil, it will help to aerate but I don't think you'll get the results your looking for. A good 4 to 6 inch layer of topsoil on top of the fields will do wonders. You won't have to seed on top of the soil, the grass you have will climb on through. As far as fertilizer goes, you need to take the dirt you've got into the county extension office to get it tested. They'll tell you what you need to fertilize with and the cost is very minimal. In my experience I've never used "weed and feed" or any other pre-emergent. I think they aren't that effective in relation to their cost. We spray in the spring with 2-4-D to kill broadleaf weeds, again with 2-4-D at the end of school, and 2-3 times during the summer with a mix of 2-4-D and MSMA(kills crabgrass). Having said all of that, the most important thing in having a good field is water and plenty of it. Water, water, water, and more water. These are the things that work for us, maybe some of it will help your situation. Good luck.
