Compound fertilizer purchase criteria:

1. According to the science of fertilizer

In addition to looking at the trademark when purchasing compound fertilizer In addition to the nutrient content, you also need to pay attention to the manufacturer and place of origin. Potassium chloride contains chlorine and should not be applied to chlorine-resistant crops. The potassium of any compound fertilizer bag that is not marked with the "S" symbol is potassium chloride. It must not be applied to chlorine-resistant crops such as grapes, potatoes, tobacco, sugar beets, etc. Be sure to choose fertilizers with the "S" symbol on the bag. Compound fertilizer is a compound fertilizer composed of potassium sulfate.

2. According to crop varieties

Generally, nitrogen, phosphorus and potassium compound fertilizers are used for field crops, and nitrogen, phosphorus and potassium ternary compound fertilizers should be used for high-yield wheat fields; densely planted crops such as wheat, rice, and millet should be used , it is suitable to use powdered compound fertilizer; sparsely planted row crops such as corn should use granular compound fertilizer; vegetables, especially fruit vegetables, root vegetables and fruit trees and other economic crops need more, so nitrogen and phosphorus with higher potassium and low nitrogen should be used Potassium compound fertilizer.

3. According to soil properties

For soils that are slightly alkaline, have low organic matter content (soil pH is generally around 8.0), and are deficient in available nitrogen and phosphorus, acidic soil should generally be used. Compound fertilizers, such as monoammonium phosphate or humic acid nitrogen-phosphorus-potassium compound fertilizer, nitrogen-phosphorus compound fertilizer, are suitable. However, for a small number of red clay or acidic brown loam soils, alkaline compound fertilizers, such as diammonium phosphate, should be used.

4. According to the fertilization method

In order to improve the fertilizer efficiency of compound fertilizer, different dosage forms of compound fertilizer should be selected for different application methods. When applying as base fertilizer, granular compound fertilizer must be used, and the higher the hardness of the particles, the better, and the fertilizer effect will be the longest. Choosing a compound fertilizer in which the nitrogen in the compound fertilizer is composed of ammonium nitrogen will help improve the utilization rate of nitrogen. If used as top dressing, powdery compound fertilizer should be used, and it should be noted that the water-soluble phosphorus content in the phosphorus of the compound fertilizer should be greater than 40.
