     Conducted by the Golf Course Superintendents Association of America (GCSAA) and funded by the United States Golf Association, a recent study compared information and samples from 1,500 golf course superintendents over the period from 2006 to 2014. The information and samples gathered were then independently analyzed by scientists at PACE turf and the National Golf Foundation.

     And the study found a broad reduction in fertilizer use. Phosphate fertilizers were reduced most drastically (53%), while potash (42%) and nitrogen (34%) also showed significant reductions. All this results in 80,000 tons of nitrogen, phosphate and potash fertilizers that are no longer being applied annually.

     "This study shows us that the golf industry is doing more with less when it comes to nutrient use on golf courses," said Wendy Gelernter, co-owner of PACE Turf. "The numbers show that golf course superintendents have reduced nutrient use across the board with positive results. Conservation practices accounted for about 90 percent of the reduction in nutrient use."

     "Golf course superintendents are committed to their role as environmental stewards," said Rhett Evan,s CEO of GCSAA. "This national study further demonstrates our commitment to monitor resources used and willingness to implement change for the betterment of the environment."
