The blaze, believed to be burning around 12 acres of land, sends a large plume of thick black smoke into the sky. Emergency services rushed to the scene to extinguish it.
The fire burns a corn field near the state special school Parkwood Hall Co-Operative Academy at Beechenlea Lane.
The cause of the blaze is still unknown.
Due to the large amount of smoke, Kent Fire and Rescue Service urges nearby residents to keep their doors and windows closed.
