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 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.

Liquid Seaweed Probiotic Supplement is suitable for all farm animals, including cattle, sheep, horses, goats, alpacas, pigs, poultry, and even pets. It can be used regularly or during times when feed quality is poor or when animals are under higher stress, such as during calving, foaling, or lambing.

SONIC Liquid Seaweed Probiotic can be added to the animals’ water (dilution 1:5-1:100), or directly to their feed. It can also be used undiluted as an oral drench for sick or malnourished animals, providing a quick mineral boost. Additionally, you can spray it on dry feed, mix it with grain, use it as a grain soak (diluted), or add it to natural mineral lick blocks.

*Note: when administering diluted with water, use within 2-3 days. Enable access to a fresh water also.  Do not store in diluted form.

Yes, it supports digestion by promoting a healthy gut environment. With the combination of kelp-derived compounds, including alginates and fucoidans, and probiotic bacteria, the SONIC Liquid Seaweed Probiotic can help improve feed utilisation and nutrient absorption, which is important for overall animal performance.

Yes, SONIC Liquid Seaweed is 100% natural with no additives or preservatives, and it can be used in pregnant and lactating animals.

It’s commonly used during higher-demand periods to support condition, gut health, and nutrient uptake, and may help promote calmer behaviour in livestock, which can be beneficial during stress events such as transport and handling.
