Gibson Blue

Gibson Blue is ideal as a base or top dressing fertiliser that is a non-dusting, free flowing product that can be applied as a banded or broadcasted or can be incorporated into the soil with any sort of crop.

Gibson Blue is a compound fertiliser, this means that it is not simply a mixture of different granular fertilisers all blended together.  The consistent granule size range allows uniform application with no separation of nutrients.

Nutrient Forms:

Nitrogen is present both as nitrate and ammonium. 
The readily available nitrate-nitrogen gives an immediate growth response, while the more slowly available ammonium-nitrogen ensures a long-lasting effect.

Potassium is present as sulphate of potash only, which makes the product chloride free.

Phosphorus is in a soluble form, allowing ready uptake by plant roots and is essential for establishment and early development.

Secondary Nutrients and Micronutrients are present, with amounts tailored to horticultural production, with emphasis on calcium, sulphur, magnesium, zinc and boron.


General rates for horticultural crops are between 150 to 600 kg/ha.  The actual rates, number of applications and their timing will vary considerably for different crops and for different districts.  Before application, seek advice from your Gibsons Groundspread representative.
