COST SAVINGS
You really can see the difference, just driving up the road. We’re happy, and it has actually saved us a lot of money on extra fertilisers.
GREAT RESULTS
If I see something once and something that dramatic, I know it’s got to be doing good.
RESILIENCE
I think it’s doing a fantastic job! We have had the best year with the most tree stress.
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.

Here at SONIC Natural Farming, a biological fertiliser company based in Australia, we use a biological fermentation process to make Fish Hydrolysate Fertiliser. Cold fermentation helps retain the nutritional value and beneficial properties of the fish, while making the liquid chelated and 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 dramatically 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 Fertilisers FAQs
SONIC Biofertiliser products have a mild, non-offensive odour—nothing like the strong odour of many emulsion fertilisers. This is because these products are naturally fermented using beneficial microbes, which help maintain balance during the processing, and preventing the liquid fish and seaweed from going rancid. When spraying, you may notice the scent initially, but it will dissipate quickly.
How to Reduce Farm Odours with Beneficial Microbes
Unlike NPK fertilisers, that just feed plants (synthetic) minerals, biological fertilisers work by delivering organic minerals and boosting the soil’s microbiome—improving nutrient cycling and plant immunity. This leads to stronger, healthier crops, without the potential of mineral imbalances or runoff that NPK fertilisers can cause.
SONIC Biological Fertilisers are specially formulated using SONIC’s own Starter Cultures sourced from indigenous Australian soil microbes. These beneficial microbes are Aussie-hardy and help activate microbial populations in the soil. Fertile soil is essential for boosting nutrient availability, and enhancing crop immunity, enabling plants to better cope with Australia’s unique challenges—whether it’s drought, unpredictable weather, or pest pressures.
Naturally fermented liquid products, begin working immediately by activating soil biology and delivering bio-available nutrition to plants. Results will vary depending on your crop, soil, and growing practices. For grazing pastures, in poor condition, improvements in soil biology may take a few years to fully develop. When seeding, you can often see faster seed germination and stronger early growth. Orchard and vegetable growers typically notice improved growth, flavour, nutrient-density, and a longer shelf life.
There is no withholding period after applying SONIC biological products because they are 100% natural and non-toxic to livestock. In fact, SONIC Liquid Seaweed is a Mineral Feed Supplement, providing multiple health benefits for animals. These fertilisers are safe to use around children, livestock, and pets, allowing you to integrate them seamlessly into your farming practices without any concerns about safety or toxicity.
Liquid seaweed extracts are chemically-extracted or heat-extracted to concentrate specific minerals. These processes can result in the loss of some nutrients and trace elements. In contrast, Seaweed Biofertiliser, such as SONIC Liquid Seaweed, is cold fermented, preserving the full spectrum of minerals and trace elements in a bio-available form.

The fish waste is sourced from retail fish shops across Australia, in regions with an operational SONIC Biofertiliser Production System. The leftover fish waste is almost entirely ocean-caught fish. It is collected, placed in large barrels or IBC containers, and cold processed (fermented) using microbial cultures, until it breaks down to become a bioavailable liquid that plants can easily absorb.
