Research from Dr. Peet Landschoot, of Pennsylvania State University, shows how the timing of fall fertilization and product longevity can affect fall color response and spring green-up in cool-season turfgrass species.
A University of Guelph Research project was conducted to observe the impact of enhanced efficiency fertilizer (EEF) on turfgrass color when applied in varying ratios with urea. The EEF used was DURATION CR® 90 day controlled-release fertilizer and the results were measured by color response.
