Yes, I'm thinking about Autumn already. Why?, It's all to do with the devastating effect of Localised Dry Patch on many greens this year. I've ever had so many people get in touch. It looks like the more regular occurrence of extreme heat and long dry spells is demonstrating the problem of excessively sandy rootzones, much better than I could ever hope to explain...
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
Understanding these microhabitats and their roles can help us manage our turf more effectively. By fostering beneficial microbial communities in these areas, we can enhance plant health, improve resistance to stresses, and ultimately, maintain healthier turf.
The soil food web has become an increasingly popular term in greenkeeping and bowling green management. The problem-solution-problem, or symptoms approach to greenkeeping has been exposed as fundamentally flawed by the diminishing list of available pesticides now available to turf managers. Is there a better way to manage greens...yes. And the extraordinary discovery is that a greenkeeping program that focusses on the green as an eco-system is fully compatible with producing tight, natural turf dominated by the fine perennial Fescue and Bent grasses.
