A method for feeding granular material in an agricultural implement, comprising: providing at least two take-up zones , the extent of each of which, viewed in a horizontal plane, is defined by a roof above each take-up zone, providing an airflow (F) through the take-up zones in the direction toward an outlet from each take-up zone, providing side walls extending downward from the roof, so that a space (S), which is open in the downward direction and toward the outlet , is formed between the roof and the side walls , providing a feed zone separating two take up zones , wherein a base of each take-up zone constitutes a common base with the feed zone , feeding the material (M) to the feed zone , feeding the material (M) from the feed zone (M) to the take-up zones with the aid of gravity, so that the material falls in a direction transversely to the airflow (F) into the take-up zones and thus delimits the space (S) in the downward direction, characterised in that the method further comprises: providing a part which is adjustable between at least two positions, with the aid of the adjustable part , regulating a flow rate of the airflow (F) in the space between the roof, the side walls and the material, with the aid of the adjustable part: I) regulating a flow area for the airflow in the space, or II) controlling a flow area for a bypass flow (Ff), so that a part of the air flow (F) is led past the space, or III) controlling a height position of the side walls. providing at least two take-up zones , the extent of each of which, viewed in a horizontal plane, is defined by a roof above each take-up zone, providing an airflow (F) through the take-up zones in the direction toward an outlet from each take-up zone, providing side walls extending downward from the roof, so that a space (S), which is open in the downward direction and toward the outlet , is formed between the roof and the side walls , providing a feed zone separating two take up zones , wherein a base of each take-up zone constitutes a common base with the feed zone , feeding the material (M) to the feed zone , feeding the material (M) from the feed zone (M) to the take-up zones with the aid of gravity, so that the material falls in a direction transversely to the airflow (F) into the take-up zones and thus delimits the space (S) in the downward direction, characterised in that the method further comprises: providing a part which is adjustable between at least two positions, with the aid of the adjustable part , regulating a flow rate of the airflow (F) in the space between the roof, the side walls and the material, providing a part which is adjustable between at least two positions, with the aid of the adjustable part , regulating a flow rate of the airflow (F) in the space between the roof, the side walls and the material, with the aid of the adjustable part: I) regulating a flow area for the airflow in the space, or II) controlling a flow area for a bypass flow (Ff), so that a part of the air flow (F) is led past the space, or III) controlling a height position of the side walls.
