I am responsible for the upkeep of the lawn at my work, my job basically depends on its apperance. The lawn is approx. 4 acres and is on a steep downgrade. I work at an indoor/outdoor concert pavillion and during the summer concert months the lawn holds 18,000 people. I would be fine if the people just would just stand/sit and watch the shows. They do not. They abuse the lawn like I have never seen. Between the dancing and discarded trash, the lawn is 1/2 dirt by the end of the season. The things going against me are as follow: - the dirt gets severely compacted to a depth of about 2 inches and the grass can't grow back through. - the lawn is on a steep downgrade and the run-off fron rain washes off all the seed and product that I place down - Before I started working thewre, someone though it would be a great idea to throw down truck loads of sand. It has made the soil completely silty. - There is only days in between shows and I do not have enough time to get it to start back up. The attached picture is what I can get done with aeration, seeding and stater fert. Any suggestions would be much appreciated. Thanks.
