Turfing systems for stadia

DETAILED DESCRIPTION In accordance with this invention a plurality of turf units for forming a continuous natural grass playing surface are employed which may be transported either together or individually.
The units may be arranged in a plurality of geometries such that areas of wear can be rotated among the units to minimize stress upon individual turf units.
The turf units include improved growing pans with a fence connected to the growing pans for maintaining the top surface of the plant growing medium at a level above the side walls of the growing pans.
The outer peripheral surface of the fence extends outwardly beyond the outer peripheral surface of the side walls of the growing pan such that large empty spaces are left below the playing surface when adjacent turf units are placed into position to construct the playing surface.
Preferably, the fence comprises a plurality of fence sections, one fence section per side wall, which are rotatably connected by a hinge to a ledge of the growing pan such that the fence remains connected to the growing pan after the fence is rotated to an open position for installation of the playing surface.
In turn, each fence section preferably comprises two fence post segments which are slidably engaged to each other to facilitate operation of the fence section.
It is preferred that the turf units contain a plant growing medium and substantially entire turf plants.
Thus, while sod may be used, it is preferred that entire, fully growing and functioning plants be grown and employed.
Artificial soils having relatively light weights are preferred in accordance with the invention.
