Late Season Fertility to Reduce Incidence and Severity of Snow Mold and Improve Spring Turfgrass Performance 2009
Project Leader: F. Rossi, Department of Horticulture Cornell University
Abstract: This two-year study has confirmed some initial observations associated with increased potassium fertilization from previous potassium research at Cornell University.
1. We observed no differences in turfgrass quality ratings during the two growing season associated with potassium treatment.
2. We observed slight differences in soil K levels over the two years but only associated with the highest late season K rate application and could not correlate these levels to any other response.
3. We observed increased snow mold as K fertilization levels were increased during and at the end of the season.
