FOR AGRICULTURE
Seaweed are naturally rich in nutrients and compounds that boost plant vitality and resilience.
Mannitol protects against drought and oxidative stress, while laminarans and fucoidans activate plant immune responses. Alginic acid enhances nutrient availability through chelation, improves soil structure and increase water retention. Also rich in minerals, amino acids, and polyphenols, seaweed extracts support enzymatic functions, nitrogen assimilation, and offer additional antioxidant and antimicrobial effects under stress conditions.
Therefore, seaweeds are increasingly used as liquid seaweed extracts in agriculture.

ALGANACT™ RANGE OF AGRI-INGREDIENTS (AGRIS)
Leveraging its expertise in seaweed extraction process, Algaia has developed Alganact™, a new range of standardized seaweed-based extracts.
Available today in liquid format , Alganact™ Agri-ingredients are produced in Brittany from harvested seaweeds (Laminaria digitata, Lamanaria hyperborea and Ascophyllum nodosum species). These extracts are processed through an IP protected extraction/separation production line, without using any chemicals.
Our team has then developed optimized extracts featuring an homogeneous composition of natural nutrients and active compounds to provide formulators with the most reliable input.
A MODULAR RANGE FOR PRECISION AGRICULTURE INDUSTRY
To better serve the diverse needs of formulators and growers, ALGANACT™ products are organized into three complementary categories:
SWE (Seaweed Extracts) : Extracts based on pure seaweed, maintaining an active compound profile close to that of the raw algae. These products reflect the natural balance of seaweed-derived nutrients.
SWA (Seaweed Actives) : Highly standardized extracts from pure seaweed, enriched in one or several bioactive compounds (either concentrated or selectively removed). Designed for more targeted applications.
SWF (Seaweed Formulations) : Tailor-made blends that combine SWE, SWA and/or external inputs to offer synergistic effects or nutritional balances adapted to specific crops or soil conditions.
