What are the key features of SONIC biological fertiliser products?

SONIC products are crafted using entirely 100% natural Australian sourced ingredients, setting them apart from traditional fertilisers. These traditionally cold fermented products go beyond organic certification, and offer a unique solution to enhance plant growth and vitality.

What is the benefit of using biological fertilisers?

Building a diverse microbial community in the soil aids nutrient cycling and disease suppression in crops.  Biological fertiliser delivers beneficial biology and minerals to the soil, reduces environmental impact from conventional fertiliser overuse, and contributes to long-term sustainability in regenerative agricultural systems.

How do biofertilisers differ from chemical fertilisers in terms of price?

While biological fertilisers may be more expensive initially, compared to chemical fertilisers, their long-term benefits include improved soil structure, increased microbial activity, and sustainable nutrient cycling. This means a decrease in biological fertiliser inputs over time, as the ecosystem naturally restores to balance.

Chemical fertilisers are manufactured synthetically and provide a quick release of nutrients to plants. They are often cheaper upfront but can lead to soil degradation over time due to nutrient imbalances, lack of organic minerals, and a decrease in soil microbial diversity.

In terms of price comparison, biological fertilisers may cost more per unit than chemical fertilisers due to their production process and sourcing of natural ingredients. However, the long-term benefits and sustainability factors associated with biological fertilisers often outweigh the initial cost difference.

Are there any discounts available for purchasing bulk quantities?

Yes, bulk supply discounts apply for 180L+ made to order products. Farm-based production services offer the best value with a number of cost savings benefits. On-farm Production Services start from 2,160L+ of combined products scheduled in fresh batches over an entire year.

Does biological fertiliser have a shelf life or expiration date?

For optimal results, it is recommended to use SONIC Biological products within 3-6 months from the batch date. However, if stored in cool conditions, they can still be used for up to 12 months.

Are there storage recommendations to prolong the shelf life?

See our storage recommendations here Use and Storage Information (download).

Can expired biofertiliser still be used, and what are the consequences?

It is advisable to prioritise the use of fresh and active biofertilisers by storing them in a cool place. The effectiveness of biological fertiliser may be compromised once it has expired. While using expired or ‘off’ biological fertilisers may not necessarily benefit plants, it also does not pose a significant risk to them. A consequence of using expired biological fertiliser is experiencing a strong, foul odor.  Expired biological fertiliser can be safely discarded by burying in a compost.
