ABSTRACT:
A planter is provided which automatically deposits equally-spaced, sprout-bearing plugs of specially prepared nutriet soil into the ground. The planter can also be equipped with a supply tank and pipe for adding a measured quantity of gel containing water and seeds with the sprout-bearing plugs. The planter is also equipped with a melting member or piston which is heated. The piston is mounted on a counterweighted arm and moves up and down by means of a solenoid. The piston, which is suitably internally heated by an air-fuel mixture, contacts and melts an oblong hole in plastic sheeting when such sheetings was laid down on a field when it was prepared for planting. The plugs are then planted through these holes.
