Golf course turfgrasses are managed as highly manicured playing fields, maintained to optimize turfgrass health and aesthetic value and, approximately 16,000 golf courses are operated for public or private use in the United States.  Frequent fertilization and supplemental irrigation are often used to promote turfgrass health and create an acceptable playing field, yet organic sources of nitrogen (N) are utilized sparingly.
