Hort Americas, in partnership with Avé Organics, is now offering OAN 10‑0‑0, an organic nitrogen fertilizer that delivers a 100% plant‑available source of nitrogen to growers in a ready‑to‑use liquid formulation.

Organic growers now have access to a sustainably derived nitrogen solution that is pathogen‑free, weed‑free, and easy to apply through fertigation, banded, broadcast, or foliar methods. Besides being produced in the U.S., it is also already OMRI-approved.

“OAN 10‑0‑0 is the next step in creating sustainable and productive organic systems,” says Chris Higgins, President of Hort Americas. “It gives growers the immediate uptake of nitrate nitrogen and the lasting benefits of ammonium nitrogen. It also does this without the handling challenges, logistics issues, odor, or inconsistencies of traditional inputs.”

Unlike most organic sources that require slow mineralization, OAN 10‑0‑0 provides a 50/50 blend of nitrate and ammonium that’s available right away. The production process uses the VARCOR system, which captures and converts ammonia from digestate into concentrated organic liquid nitrogen, organic pellets, and clean water. This method uses 90% less energy than traditional drying methods and achieves a greenhouse‑gas‑negative footprint.
