Standard for purchasing compound fertilizer:
1, according to fertilizer science
The purchase of compound fertilizer depends not only on the trademark and nutrient content, but also on the fact that potassium chloride from manufacturers and producing areas contains chlorine, so it is not suitable for chlorine-free crops. Where the "S" symbol is not marked on the compound fertilizer packaging bag, the potassium is potassium chloride. Chlorine-free crops such as grapes, potatoes, tobacco and sugar beet. Do not apply. The compound fertilizer marked with "S" in the fertilizer bag must be selected, that is, the compound fertilizer composed of potassium sulfate.
2. According to crop varieties
Nitrogen, phosphorus and potassium compound fertilizer should be used for general field crops, and nitrogen, phosphorus and potassium ternary compound fertilizer should be used for high-yield wheat fields; Powdered compound fertilizer is suitable for densely planted crops such as wheat, rice and millet. Granular compound fertilizer should be used for sparse and intertillage crops such as corn; Vegetables, especially fruits and vegetables, root vegetables, fruit trees and other cash crops need more, so nitrogen, phosphorus and potassium compound fertilizers with higher potassium content and lower nitrogen content should be selected.
3. According to soil characteristics
Acid compound fertilizers, such as monoammonium phosphate or humic acid NPK compound fertilizer, NPK compound fertilizer, etc., are generally suitable for soils with weak alkalinity, low organic matter content (soil ph is generally around 8.0) and lack of effective nitrogen and phosphorus. But for a few red clay or acidic brown soil, alkaline compound fertilizer, such as diammonium phosphate, should be selected.
4, according to the fertilization method
In order to improve the fertilizer efficiency of compound fertilizer, different application methods should choose different compound fertilizer formulations. Granular compound fertilizer must be used as base fertilizer. The higher the hardness of granules, the better the fertilizer efficiency and the longest the fertilizer efficiency. Choosing ammonium nitrogen as nitrogen in compound fertilizer is beneficial to improve nitrogen utilization rate. Powder compound fertilizer should be used for topdressing, and the content of water-soluble phosphorus in compound fertilizer should be greater than 40%.
