Purpose Built for Compatibility

Not every kelp extract is designed for formulation.

KelFlo™ has been developed with one objective in mind: to produce a highly compatible liquid extract that blends easily with liquid fertilisers and other crop nutrition products without the excessive viscosity often associated with traditional kelp extracts.

By carefully controlling the extraction process, Radikelp minimises unnecessary alginate release while retaining the naturally beneficial components of Ecklonia maxima. The result is a free-flowing product that remains easy to pump, mix and apply across a wide range of agricultural systems.

Whether incorporated into foliar sprays or blended into liquid fertiliser programmes, KelFlo™ delivers dependable performance with excellent handling characteristics.


Gentle Extraction, Natural Performance.

Many dried kelp extracts rely on strong alkaline chemicals and aggressive processing to maximise extraction yield. While effective at breaking down seaweed tissue, these methods can alter naturally occurring bioactive compounds and generate chemical waste.

KelFlo™ follows a different philosophy.

Our proprietary slow-release water hydrolysis process gently releases naturally occurring compounds using water alone—without harsh alkalis, excessive heat or high-pressure extraction. This carefully controlled approach helps preserve the natural qualities of the kelp while producing a clean extract that is both effective and easy to formulate.


Naturally Derived Benefits

Produced from South African Ecklonia maxima, KelFlo™ provides a naturally occurring spectrum of marine-derived compounds that help support healthy crop development by:

  • Encouraging vigorous root and shoot growth.
  • Improving nutrient uptake and fertiliser efficiency.
  • Supporting plant resilience during environmental stress.
  • Promoting healthy crop establishment and overall plant vigour.
  • Complementing balanced crop nutrition programmes.

KelFlo™ is particularly well suited to foliar application, where its low-viscosity characteristics and excellent compatibility allow it to integrate seamlessly into existing spray programmes.


Sustainable by Nature

Responsibly sourced washed-up Ecklonia maxima provides an abundant and renewable raw material while reducing pressure on marine harvesting operations.

The extraction process uses no harsh chemicals, producing an entirely organic residual biomass that is suitable for composting and other sustainable end uses. By combining responsible sourcing with a cleaner extraction process, KelFlo™ offers an environmentally conscious solution without compromising product quality.
