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 Special K 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 Special K is a soluble fertiliser alternative to dry spread complete fertilisers and can become the basis for a complete fertiliser program, especially where plants require additional Potassium. The specific formulation of Diamond Special K is ideal for plants later in the growing season where size, quality or flowering is the main requirement.
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 Special K is suitable for application via irrigation systems (fertigation) in soil grown crops or hydroponic systems . It dissolves rapidly and completely and remains in solution ready for root adsorption or is taken in via leaf surfaces.
Campbells Diamond Special K is particularly important for:
- Improving quality of fruits and vegetables
- Flowering crops that have a higher requirement for Potassium
- 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 Special K 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 Special K and Campbells Nitro-Cal, applied during alternate fertigations. As with any fertiliser program, it is best to seek advice from your Campbell’s distributor or your local agronomist.
