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
Yes, SONIC Biofertiliser products are made using 100% Australian-sourced natural ingredients. These Biofertilisers are cold fermented and contain no added synthetic minerals, additives, or preservatives. We can provide farmers with any required information for certifying bodies to ensure compliance with organic standards.
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.
