                          3/  STUDY ONE WAS PERFORMED USING A KICK-CUTTER MECHANICAL DEVICE.  STUDIES TWO AND THREE WERE PERFORMED USING A MOTORIZED,
                              MODIFIED "EDGER" DEVICE WHICH ALSO SIMULATED UNIFORM DIVOTS.
                          4/  PHOTOS OF EQUIPMENT USED AND/OR DIGITAL FILES FOR THE DIVOTS AT EACH RECOVERY DATE ARE AVAILABLE FROM OSU TURF PROGRAM UPON
