Evaluation of Ventilation Systems under Winter Covers to Prevent Injury from Anoxia on Annual Bluegrass Putting Greens

Winter injury is a major problem for turf managers in cold climates of the northern hemisphere. This project continues work in the area of winter injury in order to discover practices that will ensure the survivability of turfgrass, particularly annual bluegrass putting greens. Olds, Alberta is a good location to conduct this research as winters are typically long and cold. However, short intermittent periods of warm weather and/or rain can create icing conditions. This can create conditions of anoxia where oxygen is completely depleted and/or carbon dioxide builds up to toxic levels. Similar conditions can occur under impermeable winter covers. The final results from this project are expected in 2015.
