Editor’s note: The June issue of Superintendent magazine features a special supplement on golf and sustainability. We were fortunate to have several advertisers/sponsors involved in the supplement to make it possible and to help educate superintendents about sustainability. We asked the sponsors to share their philosophies about sustainability as it pertains to their products. It’s clear these companies take sustainability very seriously and are committed to its economic, environmental and social components. While their stories appeared in the June issue, we’re also sharing them in this newsletter. Today, a look at Ostara Nutrient Recovery Technologies.
For superintendents interested in seizing sustainability from a nutrient standpoint, Ostara Nutrient Recovery Technologies has made it easy for them, says Patricia Crease, marketing manager for the Vancouver, British Columbia-based company, which offers Crystal Green, a plant-activated, slow-release fertilizer sustainably made from renewable sources.
“If sustainability is on your radar, we provide you with a product that’s easy to integrate into your program,” says Crease, citing Crystal Green’s environmentally friendly and economically viable components.
Crystal Green is made from phosphorus and nitrogen that’s recovered from municipal and industrial wastewater streams and transformed into a slow-release fertilizer. A blend of phosphorus, nitrogen and magnesium, Crystal Green is an enhanced-efficiency fertilizer that offers low application rates and reduced nutrient loss through leaching and runoff, according to the company.
Although phosphorus leaching and runoff has been an issue with fertilizers on turfgrass, Crystal Green reduces that risk because of its slow-release and citrate-soluble formulation, the company says.
Dan Froehlich, Ostara’s vice president of agronomy, says more superintendents are implementing environmentally friendly measures at their courses, so Crystal Green is a good fit for them. Froehlich notes that more superintendents are also doing many more things than they did 15 years ago. Crystal Green can help them there, too.
“If Crystal Green can make their jobs easier — and superintendents don’t have to make as many fertilizer applications with phosphorus and nitrogen as they did before — then we’ve taken something off their already busy plate,” Froehlich says.
While superintendents have used slow-release fertilizers for several years, they didn’t have many options for slow-release fertilizers with phosphorus, Froehlich notes. They like the peace of mind they’re getting from using Crystal Green because they know the phosphorus won’t end up in a pond or stream.
Crystal Green is gaining a reputation as a sustainable innovation, Froehlich says. More superintendents and distributors are inquiring about it.
Froehlich says superintendents need to consider sustainable new technologies from across the golf course maintenance spectrum.
“The innovative superintendents will look at those technologies and evaluate them and see which ones make sense for their courses,” he adds.
