Which chemical fertilizers should not be applied to vegetables

Some fertilizers can improve quality and yield after being used in vegetables, but some fertilizers can increase vegetable yields, but they can cause vegetables to become contaminated, causing food poisoning and even life-threatening. Ammonium nitrate and other nitrate nitrogen fertilizers generally should not be applied to vegetables, especially cabbages, vegetables, spinach and other leafy vegetables. Because the application of nitrate nitrogen fertilizer in vegetable fields will double the nitrate content of the vegetables. Nitrate is easily reduced to nitrite in the human body. Nitrite is a highly toxic substance that is extremely harmful to the human body. Ammonium chloride, potassium chloride and other chemical fertilizers containing chlorine should not be applied to crops such as tomatoes and potatoes. After the chlorinated fertilizer is decomposed in the soil, ammonia or potassium ions are absorbed by the soil and absorbed by the crops. When the concentration reaches a certain level, it will be toxic to the plant roots, which will reduce the starch and sugar content of the product. Affecting the yield and quality, but also serious crop death.
