A fully soluble fertiliser containing Nitrogen, Phosphorus, Potassium, Sulphur, Magnesium and trace elements recommended for vegetables, fruits, flowers, turf, vines and ornamentals grown in soil and soilless culture.


Campbells Diamond White is a fully water soluble, Chloride free fertiliser containing the required nutrients for consistent growth and development of a range of plants providing immediately available Nitrogen, Potassium, Phosphorus, Sulphur, Magnesium and trace elements.

Diamond White is a soluble fertiliser alternative to dry spread complete fertilisers and can become the basis for a complete fertiliser program. The specific formulation of Diamond White is ideal for plants during all growth stages and where balanced growth is the main goal.

The addition of trace elements helps to maintain balanced nutrition and is present mainly in the chelated form for maximum efficiency of uptake.


Campbells Diamond White is suitable for application via irrigation systems (fertigation) in soil grown crops, and application through hydroponic systems. It dissolves rapidly and completely and remains in solution ready for root adsorption,

Diamond White is particularly important for:

  • Balance growth, where plants require a complete range of nutrients
  • Situations where fertigated complete fertilisers are the preferred option


General fertigation rates for horticultural crops are between 25 to 70 kg/ha in field crops and approximately 1g/L in a hydroponic situation. When applying Diamond White through the irrigation system more frequently and smaller applications guarantee the nutrients are supplied to the plants without being lost due to leaching or excessive rainfall.

A more complete nutrient program would include both Campbells Diamond White and Campbells NitroCal, applied during alternate applications, however as with any fertiliser program, it is best to seek advice from your Campbell’s distributor or your local agronomist.
