What is ‘Hydrolysate’ Fertiliser?
There are different approaches to producing a hydrolysate fertiliser. In the context of agriculture, hydrolysate refers to a type of fish fertiliser that is derived from cold processed whole fish using an enzymatic process.
The production of hydrolysate involves breaking down the fish into smaller components such as proteins, amino acids, and other organic compounds.

Cold fermentation helps retain the nutritional value and beneficial properties of fish, while making the liquid solution bioavailable—easy for plants and soil microbes to uptake.
Fish Hydrolysate Fertiliser is commonly used in agriculture as a natural and sustainable source of nutrients for plants, and provides essential elements like nitrogen, phosphorus, and potassium, as well as trace elements that are beneficial for soil health and plant growth. SONIC Fish Hydrolysate Fertiliser is processed and supplied to farmers fresh, and contains no added fillers, stabilisers, preservatives or synthetic minerals.
Hydrolysate Benefits
One of the advantages of using hydrolysate as a fertiliser is its ability to release nutrients slowly over time. This gradual nutrient release ensures that plants receive a steady supply of nourishment without the risk of over-fertilisation or nutrient leaching.
Furthermore, hydrolysate, derived from whole fish for example, often contains additional bioactive compounds such as growth-promoting hormones and enzymes, that can enhance plant growth and productivity. These compounds can also help improve root development, increase nutrient absorption, stimulate microbial activity in the soil, and enhance crop yield.
Overall, hydrolysate derived from cold processed whole fish offers agricultural practitioners an effective and sustainable option for providing essential nutrients to their crops while promoting healthy soil fertility.

Fish Hydrolysate and Fish Emulsion Differences
Two different forms of fish-based fertilisers that are commonly used in gardening and agriculture are fish hydrolysate fertiliser and fish emulsion fertiliser. While both products are derived from fish, there are some key differences between them.
Fish hydrolysate is a liquid fertiliser made in Australia by breaking down whole fish or fish parts into liquid using an enzymatic or cold fermentation process. The fermentation process involves the use of natural bacteria and lactic acids to break down the proteins, oils, and other nutrients present in the fish into a more readily available liquid form for plants. The resulting liquid is rich in essential nutrients such as nitrogen, phosphorus, potassium, amino acids, and micronutrients.

Fish emulsion fertiliser is also a liquid fertiliser made from whole, or parts of, fish, however fish emulsion undergoes a different production process.
In general, fish emulsion fertiliser is produced through a heating process to extract its nutrients. While the heating process used in production can degrade some beneficial elements, fish emulsion still provides a natural source of nitrogen, phosphorus, and trace minerals to nourish plants.
Another advantage of using biological liquid fish hydrolysate fertiliser over fish emulsion fertiliser is that it tends to have a milder odour compared to the strong smell associated with fish emulsion.
Additionally, because fish hydrolysate fertiliser is produced through a cold process, to breakdown the fish, rather than heating, it retains more beneficial nutrients, enzymes, oils, and bioactive compounds. The end result is a product that can offer a great deal of fungal and microbial food, as well as promote plant growth and soil health.

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.

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.
