Superintendents have significantly decreased their use of nutrients and fertilizers, according to results from GCSAA’s recently released Nutrient Use and Management Practices Survey. The survey is part of the second phase of the Golf Course Environmental Profile and is compared to recent data from the 2006 survey. Highlights of the survey show a 53-percent reduction in phosphate use, a 42-percent reduction in potash use and a 34-percent reduction in nitrogen use. According to the survey, conservation practices accounted for 90 percent of the reduction use. The full report is now on gcsaa.org and will be featured in the July issue of GCM.
