Liquid FISH HYDROLYSATE BIOFERTILISER BENEFITS
Bio-available Nutrition
Liquid Fish Hydrolysate is a concentrated source of essential nutrients such as nitrogen, phosphorus, and potassium that have been cold-processed to become bio-available and easy to uptake by plants and soil microbes. These nutrients are crucial for the healthy growth and development of plants, promoting stronger roots, vibrant foliage, and abundant blooms.
Natural and Sustainable
Fish Hydrolysate Fertiliser is derived from marine sources, making it an environmentally friendly choice. It is produced through a natural biological fermentation process that breaks down fish waste into a nutrient-dense liquid. The organic nature of this product makes it safe to use around children, animals, and wildlife.
Improved Soil Health and Fertility
The application of liquid Fish Hydrolysate can enhance soil fertility by replenishing important trace elements and micronutrients that may be lacking in the soil. It also helps improve soil structure by promoting microbial activity, feeding beneficial fungi, increasing water retention capacity, and reducing nutrient leaching.
Increased Plant Resilience
Regular use of Fish Hydrolysate Fertiliser can strengthen plants’ immune systems, making them more resistant to diseases, pests, and environmental stressors such as drought or extreme temperatures. This leads to healthier plants that are better equipped to withstand adverse conditions.
Versatile Applications
The low odor of Fish Hydrolysate, compared to emulsions, makes it more appealing for use in various applications. It can be used as a foliar spray, soil drench, or added directly to irrigation systems without causing unpleasant smells. Liquid Fish Hydrolysate can be used on various types of plants including pasture grasses, herbs, vegetables, fruits, flowers, trees, and shrubs.
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 enzymes, amino acids, and nutrients that promote optimal plant health.
The fermentation process breaks down fish proteins into a highly bioavailable form, enhancing nutrient absorption and maximising the effectiveness of the fish liquid fertiliser.
Uses and Benefits
Liquid Fish Fertiliser has been used in agriculture for eons as a reliable and sustainable source of nutrition for plants. Rich in essential macronutrients—nitrogen, phosphorus, and potassium—this organic fertiliser fosters strong plant growth, robust root systems, and healthy flowering.
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. This holistic approach not only boosts plant vitality but also improves soil structure and fertility, offering long-term environmental benefits.
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, promoting the production of high-quality, eco-friendly crops.
The absence of harmful additives ensures that SONIC Liquid Fish Fertiliser contributes to a healthier, more resilient ecosystem, reducing the risk of soil degradation, water contamination, and biodiversity loss often associated with conventional farming methods.
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 balanced nutrient profile that benefits a wide variety of plants, from leafy vegetables to fruit-bearing trees. This efficient and sustainable approach to fertilisation makes SONIC Liquid Fish Fertiliser an essential tool for farmers looking to optimise crop yields while minimising environmental impact.
In essence, SONIC Liquid Fish is a powerful, 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 to 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 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 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.
