The show, which should have run at the Nantwich, Cheshire college on 1 October, has been cancelled due to waterlogged ground.
The hands-on event was to have used the college’s sports pitches and golf course for practical demonstrations of sportsturf and grounds maintenance machinery, but the event has been cancelled amid fears that the grounds will not recover.
College staff have contacted the exhibitors and have been trying to tell as many would-be visitors as possible.
Reaseheath’s senior sports turf lecturer Gareth Phillips said:
"We are obviously very disappointed but our duty to our students and the members of our golf club must come first. We just didn’t feel that the turf would cope with the traffic and footfall from such a big event.
"The Reaseheath Machinery Show has become a fixture in the turf professionals calendar and this would have been its fifth year in succession."
Phillips added: "We are now discussing plans for making it an even bigger and better event next year.”
