    Bio-available Nutrition

    Liquid Fish Hydrolysate Fertiliser 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 Fertiliser 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 Liquid 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 odour of SONIC Liquid Fish Fertiliser, 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 Fertiliser can be used on various types of plants including pasture grasses, herbs, vegetables, fruits, flowers, trees, and shrubs.

    Fish Hydrolysate and Fish Emulsion Differences

    Fish hydrolysate fertiliser and 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 in Australia 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 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.

    One advantage of using 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.

    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.

    SONIC Natural Farming, a biological fertiliser company based in Australia, uses a biological fermentation process to make fish hydrolysate fertiliser, which helps to retain the nutritional value, and beneficial properties of the fish, while making the liquid chelated, and bio-available, (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 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.
