Diamond Black

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.

Advantages:

Campbells Diamond Black 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 Black 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 Black is ideal for plants during fruiting and fruit fill, where low nitrogen and high potassium are required to improve size and quality.

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

Material Safety Data Sheet

Application:

Campbells Diamond Black is suitable for application via irrigation systems (fertigation) in soil grown crops and for foliar application.
It dissolves rapidly and completely and remains in solution ready for root adsorption or is taken in via leaf surfaces.

Campbells Diamond Black is particularly important for:

- Fruiting and fruit fill
- Improving size and quality in the crop with higher potassium levels
- Situations where fertigated or foliar complete fertilisers are the preferred option.

Rates:

General fertigation rates for horticultural crops are between 25-70 kg/ha in field crops. When applying Diamond Black 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. Foliar applications at a concentration of 0.25-0.5%. A more complete nutrient program would include both Campbells Diamond Black and Campbells Calcium Nitrate, applied during alternate fertigations. As with any fertiliser program, it is best to seek advice from your Campbells Diamond Black distributor or your local agronomist.
