Seaweed has long been used by coastal farmers and greenkeepers, and modern science is finally catching up to explain why. Packed with natural plant hormones, trace minerals, polysaccharides, and microbial stimulants, seaweed is one of the most effective bioactive inputs available for turfgrass.
The Science Behind the Benefits Seaweed contains powerful natural growth hormones:
- Auxins – Promote cell elongation and root initiation.
- Gibberellins – Stimulate shoot growth, seed germination, and overall plant development.
- Cytokinins – Encourage lateral growth and delay senescence (ageing) of plant tissues.
- Betaines – Help plants manage osmotic stress, improving drought tolerance.
These hormones are critical for maintaining turf resilience, particularly under stress. But many commercially available seaweed products are loaded with solids, limiting bioavailability.
Enter BioActive Seaweed Our BioActive Seaweed is formulated to be high in soluble bioactive compounds and low in inert solids. Independent testing shows:
- 141 mg/100mls of Betaines (vs 103 in a leading competitor)
- 22.5 mg/100mls of Auxins (vs 21)
- Alginic acid: 10.9 g/100mls (vs 9.2)
- Reduced solids (~6%) vs ~50% in high-solids competitor products
Despite its low viscosity and low pH, BioActive Seaweed delivers superior levels of the compounds that actually drive turf performance. This ensures better uptake, faster action, and no messy residue in tanks or on turf.
Seaweed and the Soil Food Web Beyond plant growth, seaweed feeds the microbial community that underpins a healthy green. Polysaccharides like laminarin and fucoidan stimulate beneficial soil microbes, improve aggregation, and enhance nutrient cycling.
Used regularly, seaweed applications improve:
- Root depth and density
- Stress resilience (drought, heat, wear)
- Colour and nutrient uptake
- Microbial diversity and soil structure

Conclusion Seaweed is more than an old trick—it’s a foundational input for modern natural greenkeeping. And with BioActive Seaweed, you get all the active ingredients that matter, without the filler.
If your current seaweed product is high in solids and low in science, it’s time for an upgrade. Let your turf benefit from the best of marine biology.
