More information

Potassium is a macronutrient that is essential for plant growth and development, and it plays a key role in many plant processes, such as photosynthesis, water uptake, and the regulation of stomatal opening.
Nitrogen is also a macronutrient that is required for the synthesis of amino acids, proteins, and nucleic acids in plants.

Potassium nitrate is a highly soluble fertilizer that is quickly taken up by plants, and it can be applied to a wide range of crops, including fruits, vegetables, and ornamental plants. It is particularly beneficial for crops that have a high demand for potassium and nitrogen, such as tomatoes, peppers, and lettuce.

Kalisalpeter potassium nitrate

Kalisalpeter (potassium nitrate) is a source of nitrogen and potassium for use in fertilizer solutions in the agricultural and horticultural (greenhouse)sectors. Potassium determines yield and ensures optimal water management, resistance to stress and obtaining a robust and strong plant. Increases nitrogen utilisation and also contributes to a plant’s resistance to frost.

Nitrogen is the driving force behind fertilisation. Nitrogen promotes plant growth and photosynthesis. Nitrogen also postpones the ageing process.


Potassium oxide K2O 46.0%
