Onboard With Ulva
In April 2025, we explored the idea of expanding seaweed cultivation NY to include ulva!
This has the potential to increase bioremediation efforts (both in waterways and on shorelines), expand accessibility (to those who don’t have access to waterways for cultivation), and improve the nutritional profile of soil amendments being produced!
If you don’t have time to watch the entire video,
here are some key highlights:
Ulva Diversity: Long Island is home to at least six species of Ulva, with significant visual variations even within the same species.
Similar Benefits to Kelp: Ulva offers many of the same beneficial properties as kelp- and it’s even easier to grow.
Enhanced Soil Benefits: Combining Ulva and kelp can provide greater benefits to soil and gardens compared to using only sugar kelp.
Increased Accessibility through Wild Harvesting: Ulva can be wild-harvested in areas experiencing eutrophication without disturbing habitats, making it accessible to individuals without boats or businesses. Participants noted large amounts of seaweed (Ulva) during beach cleanups, presenting an opportunity to use it for soil and garden products.
Wider Salinity Tolerance: Ulva can thrive in a broader range of salinity levels, allowing it to grow successfully in more diverse locations, often naturally.
