Management practices


Both N and K are required by plants to support harvest quality, protein formation, disease resistance and water-use efficiency. Therefore, to support healthy growth, farmers often apply KNO₃ to soil or through the irrigation system during the growing season.

Potassium nitrate accounts for only a small portion of the global K fertilizer market. It’s primarily used where its unique composition and properties can provide specific benefits to growers. Further, it’s easy to handle and apply, and is compatible with many other fertilizers, including specialty fertilizers for many high-value specialty crops, as well as those used on grain and fiber crops.

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.

Non-agricultural uses:

Crop Nutrition Potassium Nitrate  Granule KNO3 has long been used for fireworks and gunpowder. It’s now more commonly added to food to maintain the quality of meat and cheese. Specialty toothpastes often contain KNO₃ to alleviate tooth sensitivity. A mixture of KNO₃ and sodium nitrate (NaNO₃) is used for storing heat in solar energy installations.
