this document relates to a method and a device for feeding granular material in an agricultural implement and to an agricultural implement comprising such a device . the method comprises providing a take - up zone , the extent of which , viewed in a horizontal plane , is defined by a roof above the take - up zone , providing side walls extending downward from the roof , so that a space , which is open in the downward direction and toward an outlet , is formed between the roof and the side walls , providing an airflow through the take - up zone in the direction toward the outlet from the take - up zone , feeding the material to the take - up zone with the aid of gravity , so that the material falls in a direction transversely to the airflow into the take - up zone and thus delimits the space in the downward direction , providing a part which is adjustable between at least two positions , and , with the aid of the adjustable part , regulating a flow rate of the airflow in a space between the material and the roof .
