Organic Matter Concentrationof Creeping Bentgrass Putting Greens in theContinental U.S. and Resident Management Impact

摘要

SOIL ORGANIC MATTER (SOM) accumulation in creeping bent-grass (Agrostis stolonifera L.; CB) putting greens has been a concern for decades. Gaussoin et al. (2013) summarized the negative effects associated with excessive SOM (thatch-mat), including decreased water infiltration, localized dry spots, reduced high and low temperature tolerances, increased pest problems, and reduced pesticide effectiveness. The objective of this study was to survey SOM concentrations in CB greens throughout the continental U.S. to determine management practices, and/or their interactions, that significantly affect green OM content. Regression techniques were used to determine the significance of various management practices and site-specific characteristics on green OM content.
