I'm guessing that when the decision was made to seed on site, various alarm bells were sounded by Strathayr, so maybe the accountability is a lot more difficult to pinpoint.....who knows.
From my experience, you don't try a new way of doing things until it has been tried and tested many times over. So Ellerslie has turned into one big experiment
If you have ever been to Turfgrass NZ, the company that produces Ready Lawn in NZ, you will see that all the special conditions for growing turf are rigorously set up, including the testing, soil conditions, fertilising, irrigation, and regularly monitored. This will be how Strathayr grow their turf in Aus.
These are conditions very hard to reproduce and control on a racecourse.
