Can I blend Honeywell Sulf-N PRO fertilizers with organic N sources?
Yes. The nitrogen in Sulf-N PRO ammonium sulfate is readily available, which makes it an excellent complement to organic N sources, which frequently contain a large percentage of slow release N and a small percentage of soluble N. In fact, research trials have demonstrated that Sulf-N PRO ammonium sulfate produces superior turf quality versus other soluble N sources when blended with organic nitrogen.
