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.


Campbells Diamond 19 Carat 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 19 Carat 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 19 Carat is ideal for plants during their establishment and early growth stages, where development of new shoots and leaves is the main goal or for crops that require additional Nitrogen and Phosphorus.

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


Campbells Diamond 19 Carat is suitable for application via irrigation systems (fertigation) in soil grown crops. It dissolves rapidly and completely and remains in solution ready for root adsorption. Use Diamond 19 Carat for:

  • Establishment and early growth or where plants require additional Nitrogen and Phosphorus
  • Additional vigour or development of new shoots, canopies or foliage
  • 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. When applying Diamond 19 Carat 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 19 Carat and a choice of one of the Campbells NitroCal range, 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.
