Audited Supplier Potassium Nitrate Agricultural Fertilizer Grade NOP 13-0-46 White Crystal Powder
According to reports, potassium nitrate is an important industrial raw material as well as an important chlorine-free nitrogen and potassium compound fertilizer. World) About 75% of potassium nitrate is used in agricultural fertilizers, 10% is used in TV bulbs and special glass, and the remaining part is used in industrial industries. Potassium nitrate used in agriculture is a high-quality fertilizer containing N13% and K2O46%, and there is no residue after application. It is a high-quality fertilizer for chlorine-free crops such as tobacco, coffee, tomatoes, grapes, citrus, tea leaves, etc. Potassium nitrate is not only a high potassium content, but also a nitrogen-potassium compound fertilizer with good water solubility, low acidity in the solution, easy for plants to absorb, suitable for any crops and any season, and has broad-spectrum applicability.

How to apply potassium nitrate?
Potassium Nitrate Agricultural Fertilizer Grade NOP 13-0-46 White Crystal Powder has high solubility in water. Potassium nitrate can be completely and quickly dissolved in water, making it an ideal choice for irrigation and fertilization and foliar spraying. The solubility of potassium nitrate in water increases with the increase of water temperature. Potassium nitrate has no moisture absorption. It can be stored in bags or in bulk, and will not cause agglomeration or intractable problems due to moisture absorption. Potassium nitrate can be mixed with other fertilizers. It will not block the dripper or spray head due to water insoluble matter, so it can be used to produce canned products with different formulas. Potassium nitrate is non-volatile. Unlike ammonium, the nitrate in potassium nitrate has no volatility, so it is not necessary to bury it in the soil when topdressing, just drip or sprinkle irrigation directly.
Reference dosage of potassium nitrate on various crops
1. Apple: 10-15 kg in the later stage, with two flushes.
2. Grapes: Use 5 kg for one-third of the color of grapes, once to promote redness.
3. Watermelon, melon, winter melon, etc.: 4-6 kg once or 2-3 kg twice in the later stage.
4. Banana: 5 kg once during the fruit-bearing period, 3-4 times.
5. Beans, eggplants, peppers, tomatoes and other fruits and vegetables: 3-5 kg, once every half a month.
Precautions for the use of potassium nitrate
1. It is used for paddy soil application, not suitable for rainy season soil application.
2. It can't completely replace organic fertilizer and NPK. It should be used in conjunction during the entire growth period of the crop. It can be used alone or in combination during the specific period of crop growth.
3. Fruits and vegetables are flushed as soon as possible after each crop of fruit is picked. The tree vigor can be restored as soon as possible, so that the next crop can be harvested and harvested as soon as possible.
4. If it is a one-time harvest of fruit trees (for example: citrus, apples, grapes), it must be flushed 30 days before harvest, 15 days before harvest. It can make the fruit bright in color, smooth in skin color, prolonged storage period, and high selling price. In the fruit tree swelling period, it can also be combined with flushing twice.
5. It should not be regarded as potassium sulphate fertilizer. It should be mistakenly used as pure potassium to avoid excessive application of nitrogen fertilizer.
6. Potassium nitrate should not be mixed with superphosphate and fresh organic fertilizer when applied as a base fertilizer to avoid loss of nitrogen.
7. Potassium nitrate is a strong oxidant. It cannot be stacked near heat sources and flammable and explosive materials during storage to prevent fire.
