主权项 1. A sow housing for singulated sowing of seeds, comprising a seed bin and a rotating seed element having a wall that has a plurality of through holes, each hole being arranged to, during a first part of the revolution of the hole, retain a seed as a consequence of pressure difference between the two sides of the wall, which pressure difference is accomplished by a positive pressure being maintained on the side of the wall where the seeds are situated, and each hole being arranged to, during a second part of the revolution of the hole, pass a release area (SL) in which a roll or a roller is arranged at each hole array or all hole arrays and that rollingly plugs up the hole that is on the outside of this hole for the removal of seed from the hole, wherein a cover is arranged on the same side of the wall at which the seeds are retained and is arranged to cover each hole during a third part of the revolution of the hole from the release area (SL) where the seeds are removed and up to the area where new seeds are captured by the drum, which third part is ⅛-½ of a revolution.
