Description
1. Potassium nitrate is a two-way compound fertilizer of nitrogen and potassium, of which nitrogen is 13.5 and potassium is 46. Potassium nitrate is easy to move in the soil, which is suitable for top dressing of crops, especially in the middle and late stages.
2. The nitrogen in potassium nitrate is nitrate nitrogen, which is conducive to crop absorption, and the potassium content is relatively high, so it is used more in the crop expansion period, and the effect is more obvious. However, in some crops during the coloring period, potassium nitrate
The dosage should be cautious, as excessive use will cause the fruit to not be colored due to too much nitrogen.
3. Potassium nitrate is used more in tobacco, grape fruit trees, melons, fruits and vegetables and other cash crops, with fast fertilizer effect and good quality of agricultural products.
4. Nitrate absorbs heat in the process of dissolving, so it should be used in small quantities as much as possible in winter and used with humic acid products.
5. Due to the anion antagonism between NO3- (nitrate) and Cl- (chloride ion), potassium nitrate can resist the absorption of Cl- (chloride ion) in the soil by crops.
6. In some soil environments, NO3- (nitrate) in potassium nitrate is absorbed faster by crops, so a small amount of residual potassium ions are absorbed by the soil, or weak acids and strong alkali salts such as K2CO3 (potassium carbonate) are generated, and potassium nitrate is a physiological alkaline fertilizer in such soils, so it is more suitable for use in acidic soils.
