The principal researcher for this project is Katie Dodson, Olds College. The study will focus on fall fertilization practices that will maximize the cold hardiness of turfgrass in cold climates. Little information exists on this important issue and the recommendations that have come from research conducted have been somewhat contradictory. Nitrogen and potassium will be applied at various rates and intervals in the fall period in order to determine application effects on cold hardiness. Results from the study are expected to provide specific recommendations for turf managers on fall fertilization in order to ensure maximum cold hardiness. The study is expected to take three years, ending in May 2016.
