Fire crews had to work throughout the night on Tuesday (December 3) when a 200-tonne stack of hay caught fire in Hockliffe.
The fire started at about 6.20pm in Trinity Hall Farm on the A5 north of Dunstable. Two appliances from Beds Fire attended.
However, due to the density of the bales of hay, water jets were ‘repelled’ and firefighters were forced to allow the blaze to burn out.
Fire crews had to be rotated every four hours, as firefighters worked to minimise the risk of the fire spreading to other nearby stacks.
A Beds Fire spokesman said that crews were also concerned about gasses from a nearby biological composting plant.
As of 11am today (December 4), crews are still in attendance.
The spokesman added: “It has been a long shift.
“Inspections will be carried out after the fire has died down. Jets would not work on the hay because like thatched roofs they are designed to keep out the elements.”
