FAQs
Biological Fertiliser FAQs
Conventional synthetic fertilisers are designed to deliver nutrients rapidly, creating fast and predictable plant responses. When nitrogen, phosphorus, and potassium are applied in synthetic forms, plants often respond with quick greening and a surge in biomass.
Biological fertilisers, on the other hand, work in a fundamentally different way to conventional synthetic inputs. Rather than supplying nutrients in a readily available chemical form, they focus on supporting the living processes within the soil that naturally create fertility over time.

Liquid seaweed extracts, such as Seasol, are usually produced using chemical or heat extraction to concentrate certain compounds. While these products are widely used, the process can reduce some of the natural components of the seaweed. Seaweed biofertiliser, on the other hand, is cold fermented, preserving a wider range of nutrients and natural compounds in a form that supports soil biology and plant uptake.

We service all regions across Australia for both product supply and on-farm production systems. Fresh processed biological fertilisers are delivered nationwide.
For on-farm systems and training, we work with both local and remote operations. Where in-person visits aren’t practical, we provide live video training and guided setup to ensure you can confidently get your system up and running without a hitch.
We source both fresh and dried fish waste, generated after processing for human consumption, from a network of fish shops and processors handling ocean-caught fish across Australia. By utilising these by-products, we help divert organic waste from landfill and repurpose it into valuable liquid fish hydrolysate biological fertiliser.
