A method and device for improving the efficiency of mechanical transplanting, wherein seedling balls carrying no seedlings or undersize seedlings are automatically removed prior to the planting stage. Several seedling balls are simultaneously extracted from a common cultivation tray and deficient balls are detected and removed. The deficit caused by a removed seedling ball is compensated by momentarily increasing the rate of feeding balls from the tray. No separate replacement seedling supply is required.

Method and device for improving the transplanting of seedlings

This invention relates to an automatic method for planting balled seedlings grown in container trays. According to this invention, the balled seedling (7) is removed from the container by taking hold of it from the top with a fork-like gripping element (16) and transferring it into the ground. For this, a gripping prong (16) which remains in position at the gripping stage and into which the seedling is pushed is used. The seedlings can be planted without breakage or problems and in the correct position.
