A Location-Based Model of Organic Matter Fate within the Sand-Based Surface Layer of a Putting Green
Ohio State University
Managing soil organic matter (SOM) in golf course putting greens is a major agronomic challenge facing golf course superintendents. If organic matter levels become excessive, the putting surface will be soft, bumpy and prone to disease and scalping. Yet measures to control organic matter accumulation such as topdressing and core aeration are commonly disruptive and result in player dissatisfaction and reduced course revenues. This article describes a location-based simulation model of organic matter accumulation, mineralization, dilution and removal to track the fate of SOM in the sand-based surface layer of a putting green. This will provide superintendents a decision support tool to better manage organic matter within their putting greens.
