Abstract
A flexible, continuous web of a protective foldable tape with borders of pressure sensitive adhesive on each of its longitudinal edges for automated securing of the tape to a pre-installed mulch system. The tape is wound about a core forming a cylindrical roll. In application, the protective tape is adhered to the mulch bed as it unwinds from a spindle centered above the bed by pressing the adhesive zones against the mulch covering the bed. The spindle is mounted on farm equipment capable of tracking the bed path. The equipment can be self-propelled or pulled by a tractor. Prior to dispensing the tape, the bed can be fitted with support devices such as hoops, stakes or wire.
