The striking farmers began their protest in the town of Saint-Lo at 6am on Wednesday morning, driving through the streets in their tractors and honking their horns.
Around 150 of them gathered in front of the local prefecture to burn tyres, straw, and to dump 30,000 litres of liquid manure, reported Le Parisien.
They also tried to break through the front gates of the prefecture.

Armed riot police were called to the scene, and were forced to use tear gas to disperse the crowds.
An opinion poll published earlier this month revealed that 86 percent of French people support the protests of the farmers, who have been blocking highways and access to tourist attractions in their bid to be heard.
Only five percent of the population believe the radical protests by farmers were “unjustified”.
