As the trend toward restricting the use of phosphorus-containing fertilizers on turfgrass continues, Crystal Green has been granted phosphorus exemptions in Michigan, Wisconsin and Virginia.
The exemptions allow golf course superintendents, sports-turf managers, sod growers, lawn-care operators and homeowners to apply this fertilizer to their turf where conventional phosphorus-containing products, such as monoammonium phosphate, are otherwise restricted or banned.
The phosphorus exemptions were granted due to the unique process used to create Crystal Green. The components in Crystal Green are recovered from nutrient-rich water streams using technology developed by Ostara Nutrient Recovery Technologies. The recovered phosphorus and nitrogen, together with magnesium are transformed into a fertilizer that is significantly higher in purity than its conventional counterparts.
