Testimonials

"I'm very excited about the increasing environmental stewardship that Crystal Green® provides in containerized crop production using a sustainable phosphorus source. Using a mineral based controlled release fertilizer (CRFs) allows for less temperature dependent release than conventional CRFs."

Dr. Jim Owen, Assistant Professor of Horticulture at Oregon State University's North Willamette Research and Extension Center

"You really have to feel this product to believe it - the prills are hard like a crystal, and dust-free which makes it much easier to manage. Performance-wise, this product can save both time and money since you only have to use half of phosphorus volume on each application because it takes eight to nine months to dissolve compared to agricultural grade MAP or DAP."

Jeff Freeman, Regional Sales Manager of Turf and Ornamental Markets for Wilco
