Firefighters are still at the scene of a large strawstack fire which was allowed to burn overnight.
The blaze broke out on College Road, Wereham, near Downham Market, just after 4.40pm on Sunday, September 8.
One appliance has remained at the scene of the blaze overnight and a fire service spokeswoman confirmed the crew were allowing the flames to burn themselves out.
She said: "We are still on at the scene.
"The crew are watching and allowing it to burn."
It is understood that approximately 7,000 square bales, each weighing 650kg, caught fire.
Two stacks were burning and a third was moved by the farmer to prevent it going up.
Two firefighter crews from Downham Market and Methwold, which tackled the large blaze, are on watching orders in the west Norfolk field for at least another 24 hours throughout the night.
On Sunday evening Norfolk Fire and Rescue Service tweeted: "We are currently dealing with a large fire in Wereham with a large plume of smoke. We urge all residents in the area to keep all windows and doors closed."
King's Lynn Police also tweeted: "@Norfolkfire are currently on scene at a large fire in Wereham. Please keep an eye out for other haystacks."
A police car was also called to the blaze.
Elsewhere in the county, firefighters from Attleborough, Hingham, and Wymondham put out a stack fire on Long Street, Great Ellingham, near Attleborough.
It broke out at around 12.40pm on September 8 and crews left just after 3.40pm.
Firefighters from North Walsham were also called to a stack fire on Nursery Drive in the town just after 5pm on September 8.
The Wereham blaze took place a day after a large farm fire on Bird's Lane, Southgate, between Aylsham and Reepham.
A large haystack and hay baler bore the brunt of the flames and two crews from Mundesley and Aylsham remained at the farm on Sunday damping down.
