Two crews from Aylesbury attended a fire involving waste materials and a vehicle.
Firefighters used one hose reel jet to extinguish the fire and then carried out damping down and turning over operations to extinguish remaining hotspots and prevent further fire spread.
Thermal imaging cameras were used to conduct a full inspection of the affected area and confirm that temperatures had reduced to safe levels.
Firefighters also provided safety advice to the landowner before leaving the scene.
