Seaweed extracts improve root development due to the presence of auxins and cytokinins, which increase root surface area and nutrient absorption capacity. This enhanced root system facilitates better uptake not only of micronutrients but also macronutrients.
The synergistic effect of micronutrients with natural plant hormones accelerates cell division, elongation, flowering, fruit set, and overall biomass production. Many studies report improved crop yields when seaweed extracts are applied regularly.

Polysaccharides in seaweed extracts act as soil conditioners improving aggregation, aeration, moisture retention – all of which indirectly enhance micronutrient availability by optimizing soil chemistry.
