Biological Fertiliser Uses
- Seed Treatment – Boost Germination
Use biological fertilisers as an inoculant to coat seeds with beneficial microbes and minerals prior to seeding. Biofertilisers can also be used as a root pre-soak prior to transplanting, to minimise transplant shock and promote strong, healthy growth.

- Foliar Feed – Crop Vitality
When applying biological fertilisers as a foliar feed treatment, nutrients are absorbed directly through the leaves, allowing for quick uptake and immediate effects on plant health and growth.

Biofertiliser Spraying
Liquid biofertilisers offer a flexible and efficient way to deliver essential nutrients directly to your crops.
Mixing Preparation
Start by filling your spray tank or mixing container with water before adding the biofertilisers, to prevent foam buildup. Once mixed, use the solution within 48 hours, and do not store in diluted form.
Spray Equipment
Suitable spray equipment includes; Boom sprayers, Airblast sprayers, Tractor-mounted sprayers, Aerial sprayers (drones and aircraft), and Fertigation systems.
For optimal performance, use larger nozzle and screen sizes, or even no screens at all. Keep spray pressure below 55 psi to ensure the product is applied effectively. After use, be sure to rinse out your tanks and flush the lines to prevent residue buildup.
Application Timing
For best results, apply biological fertilisers during rainy or overcast conditions, or in the evening, to take advantage of the moisture at night.
Avoid applying in full sun when temperatures exceed 27°C.

FAQs
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.

These products begin working immediately by stimulating soil biology and delivering bioavailable nutrients. Results vary depending on soil condition and management practices.
Early benefits such as improved seed germination and plant establishment can be seen quickly, while longer-term improvements—particularly in grazing systems—build over one to three years. In horticulture and orchards, growers often notice improved growth, quality, and extended shelf life of produce with regular use.

Liquid seaweed extracts, such as Seasol, are usually produced using chemical or heat extraction to concentrate certain compounds. While these products are widely used, the process can reduce some of the natural components of the seaweed. Seaweed biofertiliser, on the other hand, is cold fermented, preserving a wider range of nutrients and natural compounds in a form that supports soil biology and plant uptake.

We service all regions across Australia for both product supply and on-farm production systems. Fresh processed biological fertilisers are delivered nationwide.
For on-farm systems and training, we work with both local and remote operations. Where in-person visits aren’t practical, we provide live video training and guided setup to ensure you can confidently get your system up and running without a hitch.
We source both fresh and dried fish waste, generated after processing for human consumption, from a network of fish shops and processors handling ocean-caught fish across Australia. By utilising these by-products, we help divert organic waste from landfill and repurpose it into valuable liquid fish hydrolysate biological fertiliser.

SONIC biological fertilisers can help balance soil pH over time by improving overall soil function. The microbes in our biologically fermented fertilisers enhance nutrient cycling and soil structure, which can help buffer pH fluctuations and create more balanced soil conditions.
Rather than directly changing soil pH like lime or other amendments, biological fertilisers work by supporting the natural processes that help maintain a more stable and productive soil environment.

SONIC Liquid Fish and Seaweed Biological Fertilisers are used because they provide both plant nutrition and support for soil biology, helping improve overall soil health and plant performance.
Key benefits include:
• Providing fast-available nutrients for plant uptake
• Feeding and stimulating beneficial soil microbes
• Supporting nutrient cycling within the soil
• Improving root development and crop resilience
• Enhancing soil structure and long-term fertility
Liquid fish fertiliser is particularly rich in organic nitrogen and amino acids that support growth, while liquid seaweed contains trace elements and natural plant compounds that help with stress tolerance and overall plant health. Used together, they provide a balanced approach that supports both immediate plant needs and longer-term soil function.

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.
