Slow-release nitrogen (N) sources, also called “slowly available,” are a part of many turfgrass fertilization programs. They provide greater longevities of available N than quick-release sources, and are safer to use on turfgrass because of their lower burn potential. This group includes both coated and uncoated sources. Learn More
