With respect to nitrogenous fertilizers, ammonium nitrogen fertilizers should be used for rice, and ammonium chloride and urea are better. Corn, wheat and other cereal crops are equally effective with ammonium nitrogen fertilizers (such as ammonium bicarbonate, ammonium sulfate, ammonium chloride, urea) or nitrate nitrogen fertilizers (such as ammonium nitrate). Potato and sweet potato are also suitable for ammonium nitrogen fertilizer. Ammonium nitrate can improve the quality of tobacco. Ammonium nitrogen helps the combustion of tobacco. Chlorine-containing fertilizers (such as ammonium chloride) reduce the flammability of tobacco and should be avoided. In acidic soils, chemical alkaline or physiological alkaline nitrogen fertilizers should be used. In the saline-alkaline soil area, it is not suitable to purchase and use ammonium chloride containing more chloride ions. In alkaline soils, ammonium nitrate fertilizers are absorbed and utilized by crops, but they must be protected against decomposition and volatilization. Regarding phosphate fertilizer, leguminous crops (soybeans, peanuts), sugar crops (beet, sugar cane), fiber crops (cotton), potato crops (potatoes, sweet potatoes), melons, and fruit trees, the demand for phosphate fertilizers increased. Better fertilizer effect. For plots with large amounts of P fertilizers, it is not necessary to apply them every year to avoid wastage. Regarding potash fertilizer, tobacco, potato, sweet potato, sugar beet, watermelon, and fruit trees require large amounts of potassium. However, these potassium-promoting crops are not boiled and potassium chloride should not be used. Potassium chloride is also not suitable for long-term application on saline-alkali land. Base fertilizers and topdressing can be used on non-chlorinated crops, but it is not suitable for seed fertilizers. Potassium sulfate is suitable for all kinds of soil and crops and can be used as base fertilizer, seed fertilizer, topdressing fertilizer and top dressing fertilizer. With regard to sulphur and sodium fertilizers, potatoes, soybeans, peanuts and rapeseed are also hi-sulphur crops. The use of p-calcium is better than “heavy calciumâ€. Because "heavy calcium" does not contain calcium sulfate. Beets are hi-sodium crops, and sodium nitrate is a good fertilizer for sugar beets. Ammonium Chloride Chlorine crops are prohibited, but they are suitable for cotton, hemp and other crops, because chlorine can increase fiber toughness and tension. Ningbo Staneex Imp. & Exp.
