Abstract
Quartz sand is the preferred medium for constructing high quality athletic fields. As a result of play, pieces of sod become detached, and small excavations are created, which are termed “divots” herein. Grounds crews generally fill divots with sand. Investigations were conducted to determine whether amendments to the sand would improve bermudagrass (Cynodon sp.) coverage of the divots. The amendments peat (EarthMAX), biosolids (Milorganite), compost (yard clippings), and a pegylated polymer and clay coated sand (PPCCS, Maxand), mixed in various combinations with quartz sand, were used to fill uniformly constructed divots, and bermudagrass coverage of the divots was recorded over time. Mixes containing PPCCS and biosolids, with or without peat, provided greater divot coverage over time than sand or sand with added peat or compost.
