Potassium Nitrate -fertilizer for agricultural

Potassium nitrate is widely used as a compound fertilizer in agriculture, especially chlorine-free potassium compound fertilizer, and its effective components nitrogen and potassium can be quickly absorbed by crops without chemical residues. It is suitable for vegetables, fruits, flowers and some chlorine sensitive crops (such as potatoes, strawberries, beans, etc.).

The specific applications and effects of potassium nitrate in agriculture and the advantages and disadvantages compared with other compound fertilizers are as follows:

Specific application and effect
1. Nutrition: Potassium nitrate is a nitrogen-potassium compound fertilizer, containing nitrogen and potassium two main nutrients, nitrogen content is about 13.5%, potassium content is about 46%. When this high concentration of potassium fertilizer is used, potassium ions and nitrate ions can be quickly absorbed by crops, significantly improving the yield and quality of crops.
2. Suitable crops: Potassium nitrate is suitable for a variety of cash crops, such as green Onions, citrus, grapes, vegetables, beets and other chloride sensitive crops. It is especially suitable for the use of topdressing in the middle and late crops, because its nitrogen is nitrate nitrogen, which is conducive to crop absorption.
3. Soil impact: Potassium nitrate is a high-quality chlorine-free potassium fertilizer, which will not cause soil acidification and compaction, and no harmful elements remain. In addition, the water-soluble nutrient of potassium nitrate can significantly improve crop yield and quality.

Advantage
1. Rapid absorption: nitrate nitrogen and potassium ions in potassium nitrate can be rapidly absorbed by crops, with fast fertilizer efficiency and high utilization rate.
2. Chlorine-free: Potassium nitrate does not contain chlorine and will not negatively affect chlorine-sensitive crops.
3. Physical and chemical properties: potassium nitrate has good physical and chemical properties and is suitable for use in various soils.
4. No volatility: Potassium nitrate is not volatile and can be applied directly to the soil surface without covering.

Disadvantage
1. High cost: The price of potassium nitrate is relatively high, especially food grade potassium nitrate is more expensive.
2. It is not recommended to do base fertilizer: Because potassium nitrate is a quick-acting fertilizer, it is not recommended to use base fertilizer, which is usually used for topdressing.
Potassium nitrate has significant advantages in agriculture, such as rapid absorption, no chlorine, no volatility, etc., but its cost is higher and it is not suitable for base fertilizer.
