Flemish farmers are today protesting against new measures to improve the quality of groundwater. Offices of the manure bank in Bruges, Hasselt and Herentals were targeted. Farmers drove a hundred tractors to the bank in Herentals (Antwerp Province). They fear for the survival of their businesses if a new manure action plan is implemented. A draft leaked at the weekend spoke of a lower general manure norm and for some farming land a harvest ban from 1 September.
