Seaweed Bentonite Ball addresses a specific problem in the bio-stimulant market: liquid seaweed extracts are effective but expensive to transport (they are 90%+ water), have limited shelf life, and require spray equipment for application. By infusing concentrated seaweed extract into bentonite during granulation, we create a dry, shippable, spreadable granule that delivers seaweed bioactives (alginates, cytokinins, betaines, mannitol) in a slow-release format compatible with standard fertilizer spreading equipment.
The manufacturing process is temperature-controlled: bentonite is blended with concentrated seaweed extract (typically Ascophyllum nodosum or Sargassum species) during the granulation stage, and drying temperatures are kept below 60°C to preserve heat-sensitive bioactive compounds. This is a critical quality parameter — standard bentonite drying at 100°C+ would degrade the seaweed compounds and render the product no more effective than plain bentonite.
Our Bhavnagar facility produces Seaweed Ball in campaign batches aligned with the agriculture pre-season (January–March for kharif, July–August for rabi) when demand for bio-stimulant products peaks.

How Seaweed Bioactives Survive in a Dry Granule
The key technical challenge with Seaweed Bentonite Ball is preserving the bioactive compounds through processing and storage. Seaweed extracts contain cytokinins (plant growth hormones), betaines (stress tolerance compounds), alginates (soil structure improvers), and mannitol (osmotic regulator) — all of which degrade at temperatures above 60–70°C. Standard bentonite drying at 100–120°C would destroy these compounds completely.
Our solution uses a two-stage process: the bentonite is pre-dried to target moisture before seaweed infusion, then the concentrated extract is blended in at ambient temperature during the pan granulation stage. Post-granulation drying uses warm air at 45–55°C — warm enough to bring the granule to storage-stable moisture (10–12%) but cool enough to preserve bioactive integrity. QC includes a bioactivity indicator test on each production batch.

How does Seaweed Bentonite Ball compare to liquid seaweed extract?
Liquid seaweed extract provides immediate bioactivity but requires spray equipment, has limited shelf life (6–12 months), and involves high transport cost per unit of active ingredient (shipping 90%+ water). Seaweed Bentonite Ball provides slower-release bioactivity over 4–8 weeks as the granule breaks down in soil, can be applied with standard fertilizer spreaders, has 18-month shelf life, and ships as dry cargo at far lower transport cost per unit of active material.
Can I specify which seaweed species is used?
Yes, for orders above 10 MT. Ascophyllum nodosum (North Atlantic cold-water species, highest cytokinin content) and Sargassum (tropical species, cost-effective) are the two most common options. We can also process buyer-supplied seaweed extract under a toll-manufacturing arrangement.
