Ecology 4. Biotic and Abiotic Factors in Bowling Green Eco-systems

LDP, localised dry patch on bolwing green

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.

Ecology 2. Ecological Terms for Bowling Greenkeepers

ecological terms for greenkeepers

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.

Turf Resiliency. Performance Evaluation of the Bowling Green Part 10.

Turf Resiliency

Turf resiliency is one of the major factors determining bowling green performance and as such warrants close attention by the greenkeeper. Up to this point in our series on the evaluation of bowling green performance we have been dealing with attributes of grass, turf and soil that depend a lot on the greenkeeper's experience and "feel" for the turf. With resiliency we are getting closer to making more objective measurements.

The Sweet Spot

The sweet spot

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.

Greens Soil Analysis Reports and how to read them

greens soil analysis

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.

Opening Day Preparation: Getting the mower ready.

Opening Day Preparation: Getting the mower ready.

Getting the mower ready is often seen as someone else's responsibility during the close season, but great care should be taken to make sure you are not falling foul of tradition again. Relief grinding and back lapping have become an unfortunate norm in cylinder mower set up, but can be more damaging to the turf and the mower than you might expect. John Quinn explains the theory and suggests a solution that will ensure your mower gives you trouble free service and impressive results all season long.

Turf problems and how to fix them

managing turf disease

Greenkeepers are bombarded with turf problems in the form of disease, weeds, pests and disorders. Now, with many pesticides being banned and unavailable it's time for us to take back control of our turf. The good news is that it is actually easier without chemicals, because we are forced to learn more about the underlying causes of problems and become more familiar with the ecology of our greens.
