Water-soluble chlorine-free nitrogen-potassium fertilizer.
Nutrient content: total nitrogen (in the nitric form) - 13%, potassium (in
K2O equivalent) – 46%.
Suitable for all types of crops.
Especially efficient for chlorine-sensitive plants (vegetables, fruits,
tobacco, flowers).
Ideal for orchards, greenhouses and house plants.
Suitable for irrigation systems.
Produced from pure raw materials.
Excellent storage characteristics.
Suitable for either soil or foliar application.
