A method and a device for feeding granular material in an agricultural implement and an agricultural implement comprising such a device. The method includes establishing an air flow through a take-up zone in a direction toward an outlet of the take-up zone from an inlet of the take-up zone. The take-up zone, has an extend which, viewed in a horizontal plane, is defined by a roof above the take-up zone and 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. The method also includes 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, thus delimiting the space in the downward direction and adjusting an adjustable part which is adjustable between at least two positions, to regulate a flow rate of the airflow in the space between the material and the roof.
