On grass areas where there is little or no human interference in the form of excessive fertiliser and pesticides, such as in meadows or parks, the thatch layer will almost always be at the optimum level for a continued healthy turf/soil eco-system. This is due to the soil/plant relationship being in balance; a strong and sufficiently lively soil microbe population releases nutrition from the thatch layer as it decomposes naturally.
You might read about the possibility of dealing with fairy ring by using fungicides, or even be advised to use such an approach. Fungicides could well be part of the reason you have fairy ring in your turf in the first place so it’s best not to go down this road. Applying fungicide now is a sure way to cast your green back into another spin on the Circle of Decline. The correct action plan is clear and simple.
Ecology is a fascinating subject in and of itself. If you’re not convinced of that, I defy you not to be awestruck by Chris Packham’s brilliant BBC series on the subject. This particular episode is heavy on fungus, but also explains a remarkable synergy between animals and plants. The pine trees a reliant on the …
Understanding that the ecology of greens exists and what that means is more important for greenkeepers than understanding how that ecology works or indeed any of the scientific components of ecology in isolation. Stepping back and letting nature do its stuff can yield remarkable results.
In this article you'll discover how some commonly applied greenkeeping techniques are actually rather blunt instruments that can result in more harm than good. Top-dressing, applying lawn sand and fungicides are routinely applied to greens in an effort to treat the symptoms of common problems in the soil.
Keeping the bowling green eco-system in balance is important in order to minimise the exposure of our grass plants to a range of environmental stresses. These stresses can be thought of as environmental constraints to growth and regeneration and can come in many guises, such as a shortage of light, water, nutrition or extremes of temperature. Conditions within the soil …
Biotic and abiotic factors interact with each other. For example low oxygen levels in turf (abiotic) will affect the health of the turf roots directly when the soil becomes increasingly acidic making it harder for roots to extract nutrients from the soil, and indirectly by reducing the population of beneficial bacteria (biotic factors) which play a role in breaking down organic material to release nutrition.
However we choose to interact with this bowling green ecosystem (with or against nature) we will be working within a dynamic, constantly changing environment and it is vital that we understand this before stepping off into a new program of maintenance. In other words we need to think of our green as an eco-system. Getting to grips with some universal ecological terms will be useful.
Chemicals can affect the soil and the micro-organisms contained within it. Of course, in some cases this is exactly the effect that is required. Fungal pathogens such as those responsible for Fusarium disease in turf are micro-organisms and we might think, that logically, it's a good idea to be rid of these.
But is it?
Turf Grass Elasticity is an important factor in bowling green performance. Today we look a little closer at what this actually means and how it relates to our maintenance and use of the green.
