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.

These products begin working immediately by stimulating soil biology and delivering bioavailable nutrients. Results vary depending on soil condition and management practices.

Early benefits such as improved seed germination and plant establishment can be seen quickly, while longer-term improvements—particularly in grazing systems—build over one to three years. In horticulture and orchards, growers often notice improved growth, quality, and extended shelf life of produce with regular use.

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.

SONIC biological fertilisers can help balance soil pH over time by improving overall soil function. The microbes in our biologically fermented fertilisers enhance nutrient cycling and soil structure, which can help buffer pH fluctuations and create more balanced soil conditions.

Rather than directly changing soil pH like lime or other amendments, biological fertilisers work by supporting the natural processes that help maintain a more stable and productive soil environment.

SONIC Liquid Fish and Seaweed Biological Fertilisers are used because they provide both plant nutrition and support for soil biology, helping improve overall soil health and plant performance.

Key benefits include:
• Providing fast-available nutrients for plant uptake
• Feeding and stimulating beneficial soil microbes
• Supporting nutrient cycling within the soil
• Improving root development and crop resilience
• Enhancing soil structure and long-term fertility

Liquid fish fertiliser is particularly rich in organic nitrogen and amino acids that support growth, while liquid seaweed contains trace elements and natural plant compounds that help with stress tolerance and overall plant health. Used together, they provide a balanced approach that supports both immediate plant needs and longer-term soil function.
