Around 40 firefighters from across the North-east tackled a blaze in farm buildings.
The Scottish Fire and Rescue Service was called to the incident at Blackpots Farm, near Auchnagatt, shortly after 7pm last night.
Firefighters were originally called to deal with what was believed to be a shed fire but found several agricultural buildings ablaze, including one that was filled with straw – which took crews around five hours to bring under control.
White smoke could be seen billowing into the sky for miles around in the countryside as the fire raged.
In total eight appliances from the Scottish Fire and Rescue Service were called to the scene – including one from Stonehaven, more than 40 miles away from the incident at the farm.
A welfare unit was also sent to the scene later in the evening to assist firefighters dealing with the blaze.
It is understood that no evacuations were carried out by the Scottish Fire and Rescue Service and crews used hose reel jets to tackle the flames.
A spokeswoman for the Scottish Fire and Rescue Service said: “We were in attendance of a fire at a farm in the Auchnagatt area.
“The call originally came in about a shed on fire at 7.04pm but it was found to be a farm building 30 metres by 40 metres well alight, filled with straw.
“We had two appliances from Ellon and Peterhead and one appliance from Maud, Fraserburgh, Altens and Stonehaven at the fire in the Blackpots area of Auchnagatt.
“We were away from the scene shortly after midnight and the stop message came into us at 12.09am.”
A spokesman for Police Scotland confirmed they were called to the scene and said there was “no threat to life” from the blaze.
Councillor Edie Chapman, who represents the area in the Central Buchan ward, said her thoughts were with the farmer affected by the blaze.
She said: “This will be devastating for the farmer involved and their family.
“It could also be a huge loss for them because of the fire.
“I am pleased to hear that nobody was hurt in this fire and that the Scottish Fire and Rescue Service was able to put it out.
“My thoughts are with the farmer who has had to go through this.”
