Final Thoughts  Entire field was overseeded with 3 varieties of KBG at a rate of approximately 2lbs  Hampton, Bewitched, & Noble  Ryegrass has been kept off the field except for heavy wear locations within 4’ of dirt edges for easy removal with offseason big roll sod  Would absolutely use barrier boards for all edges in the future to create crisp edges and minimize contamination  Wish that we had replaced a large percentage of the irrigation lines in the warning track up to the valves with  HDPE or High Density Polyethylene  Wish that we had installed a separate supply line isolated to quick couplers  Wish we had moved valves to several consolidated points
