Abstract A continuous molding machine (10) for form- ing two chains (55) of soil plugs (50) for use in germinating seeds or otherwise growing plants. A continuous sheet of paper (22) is corrugated to con- form to a series of mold elements (14) and a slurry (32) of resin and soil mix is added over the paper to conform to the mold element shape. Another sheet of paper (38) is added over the top of the slurry (32) and the entire assembly is then passed under a series of pressure belts (42, 44, 46) during which time the slurry (32) is cured. The chain of soil plugs (50) which emerges from the pressure belts (42, 44, 46) is encased on both sides by paper (22, 38) and may be cut to provide a pair of separate soil plug chains (55).
