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
Mycorrhizal fungi and turf health go hand in hand. The symbiotic relationships that exist between our turf grass plants and soil fungi are critical to producing a high performance, perennial grass dominated sward. Here we look at the benefits of mycorrhizal relationships in turf and the techniques greenkeepers can employ to encourage them.
If your green maintenance budget was cut in half this year what would you do?
Most clubs when faced with cuts to the greenkeeping budget, will try at all costs to keep the most important work in the plan. Unfortunately, important frequently gets confused with dramatic, which means that the big expense of top-dressing in the spring and autumn usually stays in the plan and I wish it didn’t for all the reasons I’ve explained over many articles.
Meantime, the work deemed less important and which of course is less dramatic is often sidelined or dropped as a result of a fear of what might go wrong if the big, sexy stuff is missed. These big jobs “must be doing a lot of good”, or so the thinking goes, because they’re so expensive and disruptive?
The Sweet Spot in greenkeeping is when your green's Physical, Chemical and Biological components come into line to deliver results you couldn't previously have imagined were possible. Hitting that sweet spot is a lot simpler than you might imagine too, as focus on the soil's biology will naturally correct some of the worst Chemical problems and compensate for some of the worst Physical ones. There should be no problem "selling" this idea to your club either as first of all it saves money and secondly it massively improves green performance and consistency.
Transitioning your green from Poa annua to bent/fescue is not only critical to achieving a Performance Bowling Green, but is actually a realistic goal. The spongy, soft turf associated with annual meadow grass is less than ideal for bowls. Common wisdom says that this can't be done without major disruption and that even after it is achieved it wont last. This article explains in detail how to undertake the transition of your green from Poa annua to bent/fescue turf and dispels the myths about stressing Poa. This is the way to change your green permanently and without fuss. It will also save your club money on maintenance, so what's not to like?
Seaweed extracts have been found to improve the quality of fine turf by increasing turf density, colour, and uniformity. Seaweed extracts contain betaines, which are natural osmoprotectants that help grass plants retain water and maintain turgor pressure, so should be a key component in the management and recovery of LDP affected turf. It's continued use results in a green that becomes increasingly resistant to wear and tear.
On greens that have been managed in the conventional way for any length of time i.e. using pesticides and inorganic fertilisers, it’s likely that the soil microbe population will be significantly depleted. There might also be gaps in the eco-system, essentially “missing microbes”.
Understanding your greens soil analysis report isn't always at the forefront of thought of those who instigate the soil test. Too often it is merely a fertiliser sales tool with the advice given taking very little notice of the results received.
Greens soil analysis results are often confusing and use terms that are not easily understood in relation to greenkeeping practice. In this article, John sets out to change that by taking apart a typical greens soil analysis report and explaining it in terms we can all understand. More importantly it relates the results to maintenance.
