What is potassium nitrate? How is potassium nitrate used? We ask knowledgeable readers to help explainPotassium nitrate has a very wide range of uses in the agricultural market. Potassium nitrate is a binary compound fertilizer, and it is a chlorine-free potassium and nitrogen compound fertilizer. The total content of the plant nutrients potassium and nitrogen can reach about 60%, and it has good physical and chemical properties. Therefore, Zhongdi Web has compiled the advantages of potassium nitrate and the precautions for its application, listed in detail below for readers' reference.
Advantages of potassium nitrate:
Potassium nitrate is also called potassium nitre and saltpetre. Potassium nitrate is made by dissolving sodium nitrate and potassium chloride together and recrystallizing them. Potassium nitrate fertilizer is 100% plant nutrients and can be fully dissolved in water. It is a nitrogen-free potassium and nitrogen compound fertilizer that provides plants with potassium and nitrogen at a level of up to 60%, and it leaves no harmful residues.
Potassium nitrate can provide nutrients to crops under any conditions, can be used for crops in all four seasons, and will not cause salt accumulation in the soil. Because potassium nitrate is not volatile, it can be applied directly to the soil surface without the need for covering.
At the same time, the nitrate nitrogen and potassium contained in potassium nitrate are both major elements essential for crop growth, and the two have a good synergistic effect, promoting each other's absorption by crops and promoting the absorption of other nutrient elements. Therefore, in agriculture, potassium nitrate is often used as a high-concentration potassium fertilizer.
Because potassium nitrate is free of chlorine and sodium, has a low salt index, is highly water-soluble but not hygroscopic, has a high nutrient content and acts quickly, it is often used as a topdressing fertilizer.
Precautions for applying potassium nitrate:
1. After being applied to the soil, potassium nitrate moves relatively easily, so it is suitable as a topdressing for crops, but it is not suitable as a base fertilizer or seed fertilizer. It should be applied on dry land and should not be applied in paddy fields.
2. Potassium nitrate is suitable for use as a foliar topdressing (foliar fertilizer), with the most suitable concentration being between 0.6% and 2%.
3. When soaking seeds with potassium nitrate, it is best to use a potassium nitrate aqueous solution at a concentration of 0.2% for seed soaking and seed dressing.
4. Potassium nitrate cannot be applied as a potassium sulfate fertilizer, because potassium nitrate contains nitrogen fertilizer and will cause excessive nitrogen fertilizer for crops.
5. When potassium nitrate is used as a base fertilizer, it cannot be mixed with superphosphate or fresh organic fertilizer, to avoid nitrogen loss.
6. Potassium nitrate is also a raw material for making gunpowder, so during storage and transport special attention must be paid to preventing burning, high temperatures and explosions, and contact with flammable substances is prohibited.
