Abstract/Contents:"The objective of the project was to evaluate the performance of the Vertidrain 7117 MustangĀ® sub-surface aeration machine and assess its ability to improve the playing surface quality of sports fields in the cool temperate climate of Melbourne, Australia. The trial was conducted on two sportsfields in Melbourne, Australia, a 11 year media-fine sand profile and a 30 year duplex red friable clay profile both established under Kentucky bluegrass (Poa pratensis L.) and over-sown with perennial ryegrass (Lolium perenne L. cv. 'Cutter'). The study incorporated treatments of tine spacing (55x75, 55x55, 55x35 mm), tine diameter (5 and 8 mm diameter), and degree of kick (5 and 10 degrees), applied weekly. Results showed that subsurface aeration using the 8-mm needles can reduce surface hardness and soil strength, improve infiltration rate, root dry weight and turfgrass quality in the sand profile, however may cause injury of the fine root system generated in the clay loam profile. In sand profiles larger needle diameter (8-mm) can advance measurable reductions in surface hardness to one month, whereas the effects of narrow diameter needles (5-mm) were not observed for two to three months. Penetrometer resistance could be reduced, infiltration rate increased within one month using treatments of either 5 or 8-mm needles on sand profiles and 8-mm diameter needles on clay loam profiles. Increasing needle diameter significantly increased root dry weight in the sand profile, but significantly reduced root dry weight in the clay loam profile. It is suggested that larger needle diameter and the higher frequency of cultivation may have damaged the finer and numerous roots found in the clay loam profile leading to poor root dry weights. The improved root dry weights and healthy root system contributed to significantly improve turfgrass quality exhibited in the sand profile, whereas poor root weights and damaged roots provided for poor quality turf in the clay profile."
