84 GOLF COURSE MANAGEMENT 05.18 John Mascaro President of Turf-Tec International Presented in partnership with Jacobsen As you probably guess, these brown lines were the result of a hydraulic leak, coming from a piece of equipment operated by an employee with 34 years of experience at this facility. The superintendent was new to this course and had not yet purchased lights for the mowers. The employee was verticutting greens just as the sun was rising, so it was still pretty dark outside. Appar- ently, the mower started to leak hydraulic fluid, and in the dark, the longtime employee did not notice the leak. The employee who was changing cups noticed the leak and was able to catch up and stop the mower operator just as he began work on the sixth green. Since there were also no absorbents available on the course, they watered it down heavily by hand, then pencil- tine aerified the green and topdressed it with an 85/15 sand-to-seed mix. The following week, they applied a liquid fertilizer with an iron complex and also followed up with a granular fertilizer. The green recovered well, but the yellow lines were visible for some time.

The black footprints on this putting green were found during morning setup by the assistant superintendent. From a distance, it appeared to be a disease of some sort, but on closer inspection, he discovered the black material was moving. Apparently, there had been a migration of snow fleas (springtails or collembola) across the green the previous day, and when golfers unknowingly walked directly on them, they left injured snow fleas in their wake. The first time this course had observed a snow flea migration was in September on its fifth fairway. The assistant researched snow fleas and learned they are actu- ally a beneficial, insect-like animal in the hexapods subphylum. They measure less than a quarter of an inch, help decompose organic matter in the soil and feed on fungal hyphae and spores. Because of their small size, they are often overlooked despite being one of the most abundant of all macroscopic animals. The snow fleas came back several more times over the next month, always in different areas on the fifth hole. Photos submitted by Max Sheridan, the assistant superintendent at Haverhill (Mass.)
