Abstract/Contents:"There is increased interest in organic land care practices for Athletic and Recreational Fields in lieu of using conventional practices that use pesticides and chemical fertilizers. However, as the conversion from conventional practices to organic methods takes place, there is no science based information related to use of an organic system on turf sustainability and field safety. The objective of the study is to examine the long term effect on turfgrass sustainability, playing quality characteristics and soil quality using an organic land care system for athletic fields compared to a conventional maintenance system using Integrated Pest Management. The turf is grown on a silt loam at two mowing heights (3.2 and 6.4 cm). Nitrogen is applied as leaf compost supplemented with other organic based fertilizers for the organic plots. Ammonium sulfate and complete fertilizers with some slow release nitrogen are applied to the conventional plots. Treatments were set out in 2010 in a randomized complete block design, with three replications. The results are for 2014 through the Fall of 2017. Turfgrass quality was recorded 4 times per year with the organic system providing better quality at 4 dates in 2015 and 2016 with the exception of July 11, 2014 when the conventional treatment provided better turf quality. Part of the better quality in the organic system was due to decreasing crabgrass populations from 2014 through 2017. No difference in root biomass was noted in 2014 between the two systems. However, the conventional systems provided greater root biomass from samples collected in 2017. Soil bulk density values were lower in the organic system than in the conventional system in 2016 and 2017 due to its increase in organic matter. The percent aggregate stability was significantly greater in 2017 for the first time while there was no difference in the previous five years. Earthworm activity also increased in the organic system in 2017. The study will continue into 2018."
