Three acres of crop have been destroyed in a fire at Heckington Fen this morning.
Crews from Boston and Donington attended the blazing corn field reported at 10.48am.
A fire service spokesman said the firefighters extinguished it using hosereels and beaters.
Local photographer Colin Brittain was at the scene soon after it happened.
He said there was a combine trapped in the field of partially cut straw, but the farmer managed to get it out safely.
