Compost Tea is a home made spray that is applied to fine turf to increase the micro life in the soil. It reintroduces missing microbes and boosts the populations of all of the main beneficial microbe groups such as bacteria, protozoa and the all important Fungi. Some of these help to degrade thatch, turning it into valuable humus, giving life and body to the depleted and often excessively sandy soil in many bowling greens.
I've had a lot of requests to supply a general set of recommendations for winter maintenance for bowling greens. Although the full program for any green should be based on a thorough inspection and soil analysis, there are some general rules you can follow. I've also put together a suggested package of materials to help you apply this program more easily.
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?
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.
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.
Compost tea is a specially home brewed spray that will boost the microbe population in your bowling green, allowing you to encourage the finer grasses and combat dry patch, disease and thatch, naturally and effectively.
After studying this subject I can say that compost tea is an essential addition to the Performance Bowling Greens Program. Regular use of compost tea can significantly boost soil microbial activity and helps to make better use of fertiliser inputs. Correct formulation of the mixture during brewing will increase the dominance of the fine perennial grasses in the green sward.
By using compost teas, greenkeepers can reverse decades of damage caused by inorganic fertilisers, pesticides and excessive sand top-dressing.
