Advantages:

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

Potassium Nitrate is the most readily available fertiliser form of potassium and nitrogen available. The nitrate-nitrogen improves the uptake of potassium to the plant.

Specifications:

13.7% Nitrogen and 38.4% Potassium

Application:

Campbells Potassium Nitrate; 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 potassium nitrate has a special fit in the later stages of crop development, where demand for potassium is greatest.

Campbells Diamond Potassium Nitrate Greenhouse Grade is particularly important for:

- Improving yields

- Fruit and vegetable size, sugar and colour development

- Flower development of fruit trees and ornamentals.

Campbells Diamond Potassium Nitrate Greenhouse Grade:

- In not affected by temperature, so nutrients are still available when conditions are cold and wet

- Is not acidifying to the soil

- Cannot be lost to the atmosphere like urea or ammonium-based fertilisers

Rates: 

General fertigation rates for horticultural crops are between 25-70 kg/ha. When applying potassium nitrate 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 1-2%. As with any fertiliser program, it is best to seek advice from your Campbells Potassium Nitrate distributor or your local agronomist.
