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.

SONIC Biofertilisers are supplied fresh and do not contain preservatives or artificial additives. They are best used within three (3) months from the time they have finished processing. Best-before dates are marked on product containers.

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.

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.

Read article Can You Improve Soil Health WIthout Synthetic Fertilisers?

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.

Read article Can You Improve Soil Health WIthout Synthetic Fertilisers?

Yes. Liquid fish and seaweed biological fertilisers provide plant-available nutrients and organic compounds that stimulate soil biology. This helps improve nutrient cycling, root development, and overall soil function over time.

Read article Can You Improve Soil Health WIthout Synthetic Fertilisers?

Soil biology drives the breakdown of organic matter and the release of nutrients into plant-available forms. It also supports soil structure and plant resilience, making it a key part of long-term soil fertility.

Read article 4 Good Reasons To Feed Soil Microbes All Year Round

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.
