| Abstract/Contents: | "Despite significant changes in sand topdressing and injection practices the past 8 years, golf course putting greens are still vulnerable to excessive levels of organic matter which can, in severe cases, lead to catastrophic turf loss. In addition, there is evidence that too much sand introduction can be lead to other problems. Benchmarking organic matter, sand application, and nitrogen for putting greens in the Philadelphia area will give insight on the ideal range for each variable. The insight should give superintendents more confidence in maintaining their putting greens. The objective was to benchmark current trends in sand application rate, nitrogen rate, and organic matter on putting greens in the Philadelphia region. From 2016 to 2018, 36 courses (108 greens) were tested. Greens tested had at least 70% creeping bentgrass or 70% annual bluegrass growing in a sand-based soil. Future testing will focus on greens with other percent species compositions and other root zone soil profiles. Eight core samples per green were taken from 3 greens per course. Cores were sliced into four 25-mm increments from the surface and tested for percent organic matter by loss on ignition. Soil moisture, surface trueness and firmness were measured immediately after sampling. Cultivation frequency, sand application rate, nitrogen rate, and course budget category were collected through communication with the superintendent. The greens with at least 70% creeping bentgrass growing in a sand-based soil had an average percent organic matter in the 0-25 mm depth of 2.5% and a range from 0.6-10.4% whereas the 75-100 mm depth averaged 0.9% and ranged from 0.2-4.1%. Sand application amounts for the same bentgrass greens averaged 49 m3 ha-1 yr-1 and ranged from 20-72 m3 ha-1 yr-1. Nitrogen amounts averaged 115 kg ha-1 yr-1 and ranged from 24 to 196 kg ha-1 yr-1. Sampling will continue through 2019." |
