How Alkaline Hydrolysis Unlocks the Power of Seaperia Soluble Seaweed Fertiliser

The Science Behind Seaperia Soluble

Seaperia Soluble is made from Ascophyllum nodosum, a brown seaweed renowned for its powerful growth-promoting compounds. To unlock these natural benefits, the seaweed undergoes a process known as alkaline hydrolysis — one of the most effective and widely used extraction methods in the world.

This process involves soaking the seaweed in a mild alkaline solution (usually potassium hydroxide, or KOH) at low temperatures between 70°C and 100°C. The gentle heat and alkalinity work together to break down complex plant fibres — called polysaccharides — into smaller, more available forms called oligomers.

Why This Matters for Plant Growth

These smaller molecules are more easily absorbed by plants, meaning Seaperia Soluble works quickly to deliver results you can see. This is why foliar sprays made from soluble seaweed are so effective — nutrients and growth compounds can move straight into the leaves, rather than taking the long route through the soil.

Alkaline hydrolysis also transforms some of the natural compounds in the seaweed into new, highly active plant-growth molecules. These include bioavailable polyphenols and other natural stimulants that help plants manage stress, strengthen cell walls, and boost resilience to pests, disease, and drought.

Nature and Science Working Together

During this process, interactions between the seaweed’s natural compounds and the alkaline solution cause gentle rearrangements within the biomass. Rather than stripping away nutrients, this unlocks and enhances the seaweed’s natural bioactivity.

The result is a concentrated, water-soluble extract that maintains the integrity of the seaweed’s beneficial compounds — a perfect balance of nature and science working together.

Seaperia Soluble: Proven, Powerful, and Easy to Use

Because of this process, Seaperia Soluble delivers seaweed’s benefits up to five times faster when sprayed on the leaf rather than applied to the soil. It’s 100% soluble, rich in natural growth regulators, and easy to mix and apply.
