Biofertiliser Rates and Methods FAQs
No. SONIC Liquid Fish and Seaweed Biofertiliser products are natural and non-toxic, so no withholding period is required after application.
SONIC Liquid Seaweed is actually good for livestock and is used as part of the SONIC Livestock Probiotic Supplement formula. It contains naturally derived kelp compounds and beneficial microbes that support soil and plant systems, while also forming the nutrition approach used in SONIC Livestock Supplement.
Yes, they are compatible with standard spray and irrigation equipment, including boom sprayers, airblast sprayers, tractor-mounted units, drones, and fertigation systems.
For best results, fill the tank with water first, then add the product to reduce foaming. Use the mix within 48 hours and avoid storing diluted product.
The biofertilisers pass easily through most fine spray and irrigation systems without clogging. For best biological performance, use larger nozzles and screens (or none where appropriate) and keep spray pressure below 55 psi to protect the beneficial microbes.
Biofertilisers work optimally when using lower rates, more frequently. For grazing pastures and orchards, apply three or more times per year—particularly during the first one to three years of use or when transitioning from synthetic fertilisers. For small mixed crops and seedlings, apply once a week or fortnightly during early growth stages, and fortnightly to monthly for established plants.
The best time to apply biological fertilisers is during overcast conditions, just before or during rain, or later in the day when temperatures are cooler. These conditions help protect the living microbes in the fertiliser from heat and UV exposure, giving them a better chance to establish in the soil.

Biological Fertiliser FAQs
Conventional synthetic fertilisers are designed to deliver nutrients rapidly, creating fast and predictable plant responses. When nitrogen, phosphorus, and potassium are applied in synthetic forms, plants often respond with quick greening and a surge in biomass.
Biological fertilisers, on the other hand, work in a fundamentally different way to conventional synthetic inputs. Rather than supplying nutrients in a readily available chemical form, they focus on supporting the living processes within the soil that naturally create fertility over time.

The system itself is also designed to be simple and sustainable. Filters, filtration units, and battery-operated transfer pumps are supplied or recommended, allowing the entire process to operate off-grid without the need for mains power.
Soil Health FAQs
Yes. Soil health can be improved without relying on synthetic fertilisers by increasing organic matter, supporting soil biology, and using inputs such as liquid fish and seaweed biofertilisers. These approaches help improve nutrient availability, soil structure, and long-term fertility by supporting natural nutrient cycling within the soil.

The fastest way is to combine organic inputs with biological stimulation. Applying liquid fertilisers such as fish and seaweed can provide immediate bioavailable nutrients while also feeding and stimulating populations of beneficial soil microbes, helping to kickstart nutrient cycling and improve plant response.

Biological fertilisers activate soil biology by feeding and stimulating the existing microbes already present in the soil. Products such as liquid fish and seaweed fertilisers supply organic compounds, carbon sources, and trace nutrients that help microbes grow and become more active.
As microbial activity increases, key processes begin to improve:
• Organic matter is broken down more efficiently
• Nutrients are released into plant-available forms
• Soil structure and aggregation improve
• Root development and nutrient uptake are supported
Rather than just adding nutrients, biological fertilisers help “switch on” the soil system, allowing it to cycle nutrients more effectively and support consistent, resilient plant growth.
