  • Patent number: 4004713
    Abstract: A method and apparatus for the dosed sowing of seed comprising periodically immersing a first hollow suction tube in a supply of seeds, retaining a limited number of seeds at the tube end by creating underpressure inside said tube, bringing the suction tube above a substantially horizontal strip, on which the seeds retained at the tube end are dropped by removal of the vacuum, after which the strip with the seeds lying thereon is moved relative to a narrowing channel in such a manner that in the narrowest part of the channel there comes to lie each time only one seed, which seed is taken up by a second suction tube and transferred to a nutrient substrate, while the rest of the seeds lying on the strip are returned to the supply.
