At its most basic, the answer is that excessive use of sand on bowling greens causes the under lying soil to become inert; lacking life or the complex web of interactions that go to make healthy, high performance turf. The natural balance of the soil/turf ecosystem is upset and the green will never be capable of consistent high performance for as long as the folly of top dressing is allowed to continue.
As greenkeepers, we understand the importance of maintaining a healthy, vibrant and resilient green. In over 40 years of greenkeeping, however, I've noticed that a lot of what passes for greenkeeping has actually been very damaging to our soils, making it increasingly difficult to produce a good surface, reliably and economically.
A lot of greens are now difficult to maintain, exhibiting a host of common problems such as Localised Dry Patch, Moss Infestation, Excess Thatch, Disease, Thinning Grass Cover, Puddling, Bumps, Bad Runs and Dips
