A spokesman for Danes Castle Fire Station, Exeter, which attended the fire, said that a lot of resources had been used over a long period of time to contain the fire.
He confirmed that a 10,000 litre dam was used to maintain the water supply.
He added that it was “a significant loss for the farmer”.
A spokesman for Cullompton Fire Station said that it was a busy weekend for the station.
He said: “On Friday we were asked to help out in Plymouth due to the amount of incidents in South Devon and ended up dealing with a fire within a garden in the city.
“On Saturday morning we extinguished another fire within a rear garden, but this time in Cullompton and in the evening assisted with a barn fire in the Crediton area.
“On Sunday we assisted with a smell of gas in Fore Street, Cullompton. Big thanks to the White Hart who kept the crew refreshed and hydrated with some complimentary drinks, on a day as hot as it was it was really appreciated.”
One person who saw the East Village barn fire said that he believed a workshop was also involved in the fire.
He said that he did not know how it started, but added that “firefighters were still damping down at midday (Sunday).”
