Advantages:

Campbells Nitro-K (Potassium nitrate) is the most readily available fertiliser form of Potassium and Nitrogen currently available. The Nitrate Nitrogen improves the uptake of Potassium to the plant.

Advantages:

Campbells Nitro-K Greenhouse Grade is a fully water soluble, chloride free fertiliser containing two essential elements for crop development providing immediately available Nitrogen and Potassium.

Application:

Campbells Nitro-K Greenhouse Grade is suitable for application via irrigation systems (fertigation) and for foliar application. It dissolves rapidly and completely and remains in solution ready for root adsorption or is taken in via leaf surfaces. Timing of applications are suitable at any time during the season, however Nitro-K has a special fit in the later stages of crop development, where demand for Potassium is greatest.

Campbells Nitro-K Greenhouse Grade is particularly important for:

• Improving yields
• Fruit and vegetable size, sugar and colour development
• Flower development of fruit trees and ornamentals

Campbells Nitro-K Greenhouse Grade is not:

• Affected by temperature, so nutrients are still available when conditions are cold and wet
• Acidifying to the soil
• Lost to the atmosphere like Urea or Ammonium based fertilisers

Rates:

General fertigation rates for horticultural crops are between 25 to 70 kg/ha. When applying Nitro-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. As with any fertiliser program, it is best to seek advice from your Campbell’s distributor or your local agronomist.
