Fertilization of turfgrass takes place at every golf course. Some would call if a basic process, but the math involved is anything but basic. In this 40-minute presentation, Alec Kowalewski, Ph.D., goes over the calculations needed to provide specific amounts of Nitrogen to different areas of turf. He covers both granular and liquid fertilizers, explaining differences in detail you need to capture from the products’ packaging. You’ll come away with the information you need to do the math for both purchasing and application for different areas of your facility.
