Four fire engines were called to Abbey Farm in North Weston at about 5.20pm today.
Oxfordshire Fire and Rescue Service has had to close the A418 in both directions just before 7pm because they have had to lay their hose over the road.
Motorists had been warned, when the road was open, about the smoke billowing across the road, making driving hazardous.
