Rooted locally. Unique cold extraction process.
Oileán Glas Teoranta (OGT) is an Irish company based in south Donegal. Our work connects traditional coastal practices with modern agricultural needs, transforming natural seaweed into solutions that contribute to more sustainable farming systems.
We have developed a unique Cold Gentle Extraction process to preserve the biostimulating compounds found naturally in fresh seaweed for maximum bioavailability.
Our biostimulants
From seaweed to sustainable agriculture
Our biostimulants are made from Ascophyllum nodosum, a seaweed species which is naturally rich in beneficial compounds. These properties sustainably support plant health, resilience, and productivity.
Our sourcing
Traditional, responsible, and local
The seaweed we use is harvested manually by independent local harvesters, using traditional methods, adhering to sustainable seaweed harvesting practices.
- Hand harvesting using traditional tools
- Small-scale, seasonal activity, dependent on tidal conditions
- Controlled, low-impact approach
Seaweed sourcing is a controlled, manual, and resource-conscious activity.
A balanced approach
Our model is based on responsible resource use, combining traditional knowledge with structured monitoring to ensure environmental integrity and long-term sustainability.
