Liquid Fish Processing Methods
SONIC Natural Farming uses an innovative biological fermentation process to create its high-quality fish liquid fertiliser, also known as fish hydrolysate. This natural process ensures the fertiliser retains the full nutritional value of the fish, preserving vital amino acids and nutrients.
Uses and Benefits
Liquid Fish Fertiliser has been used in agriculture for eons as a reliable and sustainable source of nutrition for plants. It contains essential macronutrients—nitrogen, phosphorus, and potassium.
In addition to these primary nutrients, fish liquid fertiliser is packed with crucial trace elements such as calcium, magnesium, sulphur, and a variety of micronutrients that support soil health and microbial diversity.
Unique Qualities
What truly distinguishes SONIC Liquid Fish is its purity and natural integrity. Unlike many synthetic fertilisers, SONIC’s formula contains no added fillers, stabilisers, preservatives, or synthetic minerals. This makes it a completely natural, chemical-free alternative that aligns with the principles of regenerative farming.
The absence of harmful additives ensures that SONIC Liquid Fish Fertiliser contributes to a healthy ecosystem.
Moreover, the unique fermentation process employed by SONIC Natural Farming results in a product that is not only highly effective but also easy to apply, offering a naturally balanced nutrient profile that benefits a wide variety of plants, from leafy vegetables to fruit-bearing trees.
In essence, SONIC Liquid Fish is a natural solution that harnesses the full potential of ocean fish as a nutrient-rich resource that supports both plant health and long-term soil restoration.

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

Fish emulsion fertiliser is also a liquid fertiliser made from whole, or parts of, fish, however liquid fish emulsion undergoes a different production process.
In general, fish emulsion 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.
