I have question about a soccer field that my company has been asked to bid on. It is at the county YMCA and the problem is the field has areas with no grass, clumpy grass areas and just general all around poor turf. They want it gone over this fall so that in the spring the bad areas will have new grass. I am not an expert in this area of lawn care. I have had suggestions of adding a sand/peat moss mixture with grass seed or core aeration with a winterizer and overseed. I am not sure what to do or how to bid this job. We are located in Western Illinois. Any help would be greatly appreciated.
