The Most Complete Potassium Nitrate Fertilizer Knowledge Summary

Potassium nitrate is widely used in agriculture. It is a binary compound fertilizer, and it is a compound of chlorine-free potassium and nitrogen. The total content of phytonutrient potassium and nitrogen can reach about 60%, and it has good physical and chemical properties.

Potassium nitrate is also called potassium saltpeter and fire nitrate. Potassium nitrate is formed by dissolving sodium nitrate and potassium chloride together and recrystallizing. Potassium nitrate fertilizer is 100% plant nutrients and can be completely dissolved in water. It is a nitrogen-free potassium and nitrogen compound fertilizer. It can provide plants with potassium and nitrogen up to 60% of the effect, and does not leave harmful substances.

Potassium nitrate can provide nutrients to crops under any conditions, can be applied to crops in four seasons, and will not cause salt accumulation in the soil. Since potassium nitrate is not volatile, it can be directly applied to the soil surface without covering.

At the same time, the nitrate nitrogen and potassium contained in potassium nitrate are both essential elements for the growth of crops. The two have a good coordination effect, which can promote the absorption by crops and promote the absorption of other nutrients. Therefore, potassium nitrate is often used in agriculture. For high-concentration potash fertilizer.

The nitrogen in potassium nitrate is nitrate nitrogen, which is good for crop absorption. In addition, the potassium content is relatively high, so it is used more in the crop expansion period and the effect is more obvious. However, during the coloring period of some crops, the amount of potassium nitrate should be cautious. Excessive use will cause the fruit to fail to color due to excessive nitrogen.

Potassium nitrate can also luxuriate the branches and leaves of crops, and enhance the ability to resist lodging and pests. Potassium nitrate does not undergo metathesis reaction with any acid, alkali, or salt. The reason is that potassium salt and nitrate are easily soluble in water or cannot produce precipitation, gas or water.

Reference dosage of potassium nitrate on various crops:

1. Apple: In the later stage, use 10-15 kg once and use twice for flushing.

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.
