| Abstract/Contents: | "Inorganic soil amendments are currently receiving considerable interest from the turfgrass industry. Although most research has focused on applications of these amendments to sand-based putting green construction, turf managers are also applying these materials during aerification to modify the physical and chemical parameters of existing sand-based greens. In the present study, several formulations of natural zeolites, calcined clays, and diatomaceous earth were blended with sand at a 20% (v/v) amendment to sand ratio. The amended sands were applied following core-aerification (12.5 mm diameter x 75 mm depth) to an existing creeping bentgrass (Agrostis palustris Hud.) putting green built according to USGA recommendations. Recovery of the turf following aerification and surface hardness of the green following two amendment treatments were documented. In addition, all materials were analyzed for particle size analysis, cation exchange capacity, electrical conductivity, and macro- and micro-nutrient content. When analyzed alone, most of the amendments failed to meet the proper particle size distribution for inclusion in a USGA green. However, when blended with appropriate sand at a 20% ratio, particle size distribution for most products did meet USGA recommendations. The major unique chemical property of the amendments was a high cation exchange capacity (7 - 145 cmol kg-1), which facilitated pre-loading the materials with nitrogen and other nutrients. Neither higher total N nor higher CEC of the amendments affected recovery of the grass following aerification, although there were specific differences between certain amendments relative to the recovery period. After replacing approximately 15% of the upper (100 mm) rootzone with the inorganic amendments, there were no effects of the amendment on surface hardness of the green." |
