“This study is significant because it demonstrates that golf courses wishing to use an organic fertilizer can do so without sacrificing turf quality, simply by utilizing Converted Organics Turf Blend(TM) 6-0-0 organic liquid fertilizer,” said Edward J. Gildea, president of Converted Organics. “These results are especially meaningful for golf courses located in environmentally-sensitive areas.”

“Natural fertilizers must provide basic growth requirements and produce a desirable quality for commercial turfs. Our study showed that Converted Organics’ Turf Blend(R) 6-0-0 organic fertilizer, along with the urea control, displayed the most consistent high quality over the seven weeks of evaluation,” said Thomas Fermanian, Emeritus Professor of Turfgrass Management, University of Illinois and president of Fermanian Consulting, LLC. “Converted Organics Turf Blend(R) 6-0-0 shows great promise as a long-lasting nitrogen source.”

The study commenced on May 28, 2009 at the Midwest Golf House in Lemont, Illinois, home of the Chicago District Golf Association. The study compared Converted Organics’ Turf Blend 6-0-0 to urea and sulfur coated urea as standards, as well as NaturStim Liquid and granular treatments Milorganite, sulfur coated urea, L-Soy 9 and NaturStim Granular. Each treatment was applied to a 20 foot square patch of fairway turf and replicated four times. All treatments received 10 minutes of irrigation at the conclusion of all applications. Other than nitrogen fertilization, the experimental areas received the same maintenance as the remainder of the green.
