Three tonnes of straw was set ablaze in a field near Stoke Mandeville last night.
Two fire crews from Aylesbury rushed to the scene off Lower Road at 8.49pm.
Firefighters used one jet and a hose reel to put out the inferno, the smoke from which could be smelt across much of the area around Ellen Road.
