Master Greenkeeper John Quinn is the author of Performance Bowling Greens, and several other titles on Greenkeeping, Club and Business Management.
Timely applications of PotSi have been shown to be particularly effective in preventing the onset of fungal diseases. For example, applying PotSi at the early stages of a Dollar Spot outbreak can significantly reduce disease severity by fortifying the turfgrass against the pathogen. This proactive approach not only mitigates disease impact but also reduces the need for chemical fungicides, promoting a more sustainable turf management strategy .
Life after pesticides for bowling clubs, what a scary thought, or is it? Master Greenkeeper John Quinn explains why he believes the death of pesticides could be the start of a revolution in bowling green performance.
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.
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.
Today, we will look at two mechanisms of turfgrass physiology that are active in our grass plants and soil and that follow this tendency towards equilibrium, without which our turf wouldn't be able to grow and thrive.
