About 6 years ago one of my accounts had a new regulation size soccer field built by a demolition contractor that never built an athletic field before and probably haven't since. The soil that was brought in is horrible. After using organic methods the situation has improved but it is nowhere it should be. I've overseeded and don't get much germination. The field does not not drain. THe manager of the school likes to water often. I've told them many times to back off on the watering but it has fallen on deaf ears. Any thoughts on how drainage can be improved?
