Alga Sol Seaweed Fertilizer

Alga-Sol is a premium liquid seaweed extract fertilizer made from cold-pressed Ascophyllum nodosum, hand-harvested from the Argyll Coast, Scotland. Unlike standard seaweed fertilizers produced via alkaline hydrolysis, Alga-Sol uses Cell Harvest Technology — high-pressure cold extraction that preserves the full bioactive profile of the seaweed. As a plant biostimulant, Alga-Sol works alongside your regular NPK fertilizer programme to stimulate root development, improve nutrient uptake efficiency, and activate natural stress-resistance mechanisms. It contains: Cytokinins, auxins and gibberellins for root and shoot growth Mannitol (2.01%) for drought, frost and salinity protection Alginic acid (3.18%) for soil structure and moisture retention Laminarins (1.17%) to prime plant defence systems Suitable for arable crops (potatoes, wheat, barley, oilseed rape, sugar beet), sports turf and grassland, home vegetables and allotments, hydroponics, and transplanting root dips. Trusted by professional growers — used on 60% of UK Premier League grounds and backed by a 6-year independent scientific study. UK manufactured in Glasgow. pH 5–6, safe for direct foliar application.
