Fertilizer not suitable for use in vegetables

There are many types of fertilizers, and there are more than 10 commonly used ones. Some fertilizers can be used to improve the quality and yield of vegetables. Some fertilizers will affect the yield and quality of crops. Some fertilizers can increase the yield of vegetables, but it will cause toxin pollution. Cause food poisoning.
For example, ammonium nitrate and other amine nitrogen fertilizers are generally suitable for application to vegetables, especially cabbage, green vegetables, spinach and other leafy vegetables. Because nitrate fertilizer is applied to rice fields, it will increase the nitrate content of vegetables. Nitrate is easily reduced to nitrite in humans. Nitrite is a carcinogen and is extremely harmful to the human body. For example, chemical fertilizers containing chlorine components such as ammonium chloride and potassium chloride should not be applied to crops such as tomatoes, potatoes, sweet potatoes, and rehmannia. Because chlorinated fertilizers are decomposed in the soil, ammonia and potassium ions are adsorbed by the soil and cropped by the soil. Absorption, when its concentration reaches a certain level, will cause toxicity to plant roots, which can reduce the starch and sugar content of the product, affecting the yield and quality, and causing crop death in severe cases.
