Laying the groundwork.

If you're among those who have a co-op agreement with a local school system, college or university, prepping your sports fields isn't something you have to worry about. They're already in use, so all you'll have to do is take over the upkeep work (meaning mowing and watering, as well as checking for problems such as pests, weeds and the occasional hazard caused by groundhogs or gophers). If your field is artificial turf, you'll just be looking at brushing the fibers and keeping the field clean, as well as making sure all equipment is in good repair.
