Application Rates & Methods

SONIC Biological Fertilisers and Liquid Biologicals are ‘living’ products that help add naturally balanced minerals and beneficial microorganisms to the soil.

Synthetic fertilisers are inorganic compounds usually derived from by-products of the petroleum industry such as ammonium nitrate, ammonium phosphate, superphosphate, and potassium sulphate. Synthetic fertilisers do not support life in the soil and can destroy beneficial soil microorganisms.

Because these products conflict, we do not advise applying natural and synthetic fertilisers together.  


  • Spray in early morning or late evening 
  • Avoid applying during the heat of the day

Bio-Fertilisers are best applied in the cooler times of the day, when overcast or raining, particularly in the warmer months.  Applying the Fertilisers in the cooler times allows the living microbes to optimise their ability to survive, establish themselves and multiply in your soil.


Warning: Avoid spraying when temperatures climb over 27 degrees celsius, as even low rates can cause burning if applied under a hot sun.


    Filter and pre-mix the required amount of fertiliser in a separate container. This will make the fertiliser easier to mix with water in spray tank.
    Have pump running to get water agitating when adding pre-mixed fertiliser to spray tank. This will help further mix fertiliser to make a homogenous liquid.
    Remove or by-pass filters.

Other ways to apply Bio-Fertilisers includes watering can, spray pack, spray vat or through irrigation lines.

Note; Do not store in pre-mixed form.

Compost Activator


SONIC Bio-Fertilisers and Biological Solutions are concentrate products requiring dilution.  Listed rates are approximates only because this product is so safe to use, however we advise not exceeding the recommended rates.

ALWAYS USE NON-CHLORINATED WATER.  Chlorine destroys microbes.  In cases of chlorinated water allow the water to sit for 24-48 hours, allowing the chlorine to dissipate.
