Maxi K Soluble Potassium Nitrate Fertilizer -25kg is used as a source of Nitrogen (N) and potassium – two of the macronutrients for plants.

Both are required by plants to support harvest quality, protein formation, disease resistance and water-use efficiency.

The Maxi-K fertilizer is a unique source of potassium by its nutritional value and its contribution to the health and yields of plants. It increases yields and improves quality in vegetables, field crops, flowers, fruit, and nut trees.

Ideal fertilizer for growth, consistency, and coloring of fruits and flowers, low chlorine content.

Product Features and Specification:

  • Crops: Excellent for potatoes, tomatoes, peppers, aubergines, flowering plants, and fruit trees.
  • Nutrient Composition: 13% Nitrogen, 46% Potassium
  • Very Low Chlorine
  • Package size: 25kg

Maxi K: Agricultural use

Growers value fertilizing with KNO₃ especially in conditions where a highly soluble, chloride-free nutrient source is needed. In such soils, all of the N is immediately available for plant uptake as nitrate, requiring no additional microbial action and soil transformation.

  • Growers of high-value vegetable and orchard crops sometimes prefer to use a nitrate-based source of nutrition in an effort to boost yield and quality.

  • Potassium nitrate contains a relatively high proportion of K, with an N to K ratio of approximately one to three. Many crops have high K demands and can remove as much or more K than N at harvest.

  • Applications of KNO₃ to the soil are made before the growing season or as a supplement during the growing season. A diluted solution is sometimes sprayed on plant foliage to stimulate physiological processes or to overcome nutrient deficiencies.

  • Foliar application of K during fruit development advantages some crops, since this growth stage, often coincides with high K demands during the time of declining root activity and nutrient uptake.

  • It is also commonly used for greenhouse plant production and hydroponic culture.


Management practices

  • Both N and K are required by plants to support harvest quality, protein formation, disease resistance and water-use efficiency.
  • Farmers often apply KNO₃ to soil or through the irrigation system during the growing season to support healthy growth.
  • The relatively high solubility of KNO₃ under warm conditions allows for a more concentrated solution than for other common K fertilizers. However, farmers must carefully manage the water to keep the nitrate from moving below the root zone.
