As manager of the athletic fields for our land-locked college( what we have is all we got to work with), my challenge is to keep these fields in as good as shape as possible. Lately, the temperatures here in the eastern PA have remained mild. Now, the athletes are using the fields everyday for lacrosses and inter-murals as well as the kids playing pick-up games of football and frizzby. Our fields consist of dwarf varieties of blue grass and blue grass/rye fieldsand they are beginning to show some severe wear and tear. What are other folks with the same situation doing to keep your fields in playable shape?
