Dave Doherty, founder of the International Sports Turf Research Center will discuss what he has learned from twenty five years of helping superintendents and sports field managers answer these questions. It all starts with an understanding of how greens age under different management regimes and growing conditions. With this understanding, one can most effectively plan their aeration and topdressing programs.
