Firefighters called to a blaze in a large field near a derelict hospital spent almost two hours battling the flames.
The fire, which took place in a field behind Sidlaw Court, near to Pitempton Road and Strathmartine Hospital, broke out shortly before 4pm on Wednesday.
Residents spoke of how lucky it was that the smoke was blowing away from houses and how the field has been left black.
A spokeswoman for the Scottish Fire and Rescue Service said crews were called at 3.48pm.
She said: “The area of the fire was 500 metres by 500 metres. We used spades, beaters and one hose reel jet . Two appliances were sent to the scene.”
The farmer assisted using agricultural equipment to help put out the flames.
One resident, who asked not to be named, said: “It was my husband who saw it.
“He was the one who phoned the fire brigade and the police.
“The field is predominantly black. It’s lucky the wind was blowing away from the houses.”
It is believed it was the straw that was waiting to be bailed that caught fire.
Another resident said: “I think the neighbours who were out looking were quite shocked about the size of the fire.
“The wind was blowing the right way for us otherwise it could have been really bad.”
The stop signal for the fire service came in at 5.16pm.
A spokesman for Police Scotland said that straw to the rear of the old Strathmartine Hospital caught fire and that there was extensive damage to the field.
He added there was nothing to suggest it was being treated as suspicious and that no further action was being carried out.
Councillor for the Monifieth and Sidlaw area, Craig Fotheringham, praised the work of the emergency services.
He said: “I would hope that first and foremost it was not started deliberately and that no one was hurt.
“I would like to praise the emergency services. They are always excellent.
“If it was deliberately started then I condemn that, it is always a waste of scarce resources.
“I am just thankful that nobody was hurt and no property was damaged.”
The Strathmartine Hospital site has been plagued with deliberate fires since it was closed in 2003.
Firefighters were called out to the site 60 times in the past five years.
Crews have spent more than 31 hours in total battling blazes at the site in that period.
The figures included 20 deliberate fires, two accidental fires and 38 false alarms – adding up to a combined 43 hours.
