Yes. SONIC Biofertilisers contain living microorganisms, and microbial activity gradually declines after production. For best results, use the product within three months of its production date. The best-before date is printed on every container.
Freshness matters because the benefit of a biological fertiliser comes from those living microbes. When applied, they add beneficial microorganisms to the soil and can help stimulate existing soil life. This supports processes such as nutrient cycling and organic matter breakdown. The more active the microbes are at application, the better placed they are to establish in the soil.
SONIC Biofertilisers are supplied fresh and contain no preservatives or artificial additives, which is why they have a shorter shelf life than many conventional fertilisers.
