Biological Fertilisers FAQs

SONIC Liquid Fish and Seaweed Biofertilisers contain native microbial strains isolated from soils well-adapted to Australian conditions. These microbes enhance soil microbiology, support nutrient cycling, balance pH, and help remediate salt and chemical impacts. Fish and Seaweed Biofertilisers also deliver bioavailable organic minerals and trace elements essential for optimal crop growth.

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.

FeatureNatural Fertilisers (e.g., Fish Hydrolysate)Synthetic Fertilisers (e.g., Urea)
SourceDerived from natural materials like fish byproducts, compost, or seaweed.Manufactured from synthetic chemicals or mined minerals.
Nutrient CompositionContains a broad spectrum of nutrients including NPK, amino acids, and trace minerals.Primarily provides specific nutrients like NPK in concentrated forms.
Nutrient ReleaseVaries by application: Quick-release when used as a foliar spray (absorbed through leaves); slow-release when applied to soil, feeding plants over time via microbial activity.Quick-release, providing immediate nutrients to plants but often lacking sustained availability.
Soil Health ImpactEnhances soil structure, increases microbial activity, and improves water retention.Can degrade soil structure, reduce microbial life, and lead to long-term fertility decline.
Environmental ImpactLower risk of runoff and pollution; supports sustainable practices.Higher risk of leaching, runoff, and environmental harm.
Plant GrowthSupports balanced, resilient growth with improved flavour and nutrition; helps achieve higher nutrient density in crops.May stimulate fast growth but can cause imbalances or fertiliser burn; does not support high nutrient density in plants.
CostGenerally higher upfront cost; long-term savings through improved soil health and using DIY methods for production.Lower cost; requires more frequent application, as land often becomes dependent on increasing amounts each year, raising costs over time.
Application FrequencyInitially applied more frequently to activate soil biology, then less often as natural ecosystems restore balance and fertility.Frequent applications required to sustain growth; dependence increases over time, creating a perpetual input cycle.
Compatibility with Regenerative PracticesHighly compatible; supports biodiversity, carbon sequestration, and soil restoration.Small amounts may offer a temporary boost, but over time, become unnecessary as regenerative practices and natural inputs rebuild the soil.

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.

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.

No. SONIC Liquid Fish and Seaweed Biofertiliser products are 100% natural and non-toxic, with no withholding period. Safe for livestock and the environment, they integrate easily into everyday farm routines.

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

We source leftover fish waste from numerous fish shops around Australia. These shops provide us with their ocean-caught fish after it has been processed for human consumption. Once the fish is collected, it is placed in large barrels or IBC containers. Once the fish is collected, it is placed in large barrels or IBC containers. Then the fish is cold processed (fermented) using microbial cultures, until the fish breaks down and becomes a rich liquid mineral concentrate that plants can easily absorb.
