A combination of a modular tray (10) for use in forming grass turf tiles (12 ) and a removable grass turf tile formed therein is provided. The combination includes a modular tray (10) having a turf tile support surface (14) and a plurality of parallel ribs (16) formed in the support surface (14) and extending downwardly therefrom. Drainage notches (18) are formed through a lower surface of ribs (20, 16). The ribs are asymmetrically spaced with respect to a center line (22) of the support surface (14) such that stacking the modular trays in alternating orientations rotated by 180~ results in vertically staggered ribs. Sidewalls (24) extend upwardly from a periphery o f the support surface (14) to a generally uniform height above the support surface (14). Flanges (26) extend from an upper edge of the sidewalls (24) t o form a generally planar rim. A drainage material (34) is located on and generally coextensive with the turf tile support surface (14) over the ribs (16). A mixture of root zone material (44) and fiberous inclusions (46) are located on the drainage layer and has a generally uniform thickness approximately equal to a height of the sidewalls (24). Grass roots (48) are intertwined with the soil and fibers to form a grass turf tile (12) bounded by the sidewalls (24), which is removable from the support surface (14). A meth od of providing a playing field from modular grass turf tiles (12) is also provided.
