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.
