Which fertilizers should not be applied to vegetables?
At present, there are many kinds of chemical fertilizers, and there are more than 10 commonly used ones. However, although there are two types of chemical fertilizers, although the vegetables can increase the yield, they can cause pollution of vegetables, causing poisoning and even life-threatening.
Ammonium nitrate and other nitrate nitrogen fertilizers are not suitable for use in vegetables, especially cabbage, green vegetables, spinach and other leafy vegetables. Because the nitrate nitrogen fertilizer is applied to the vegetable field, the nitrate content of the vegetable is doubled, and the nitrate is easily reduced to nitrite in the human body. Nitrite is a kind of drug, which is extremely harmful to the human body and is a carcinogen.
Fertilizers containing chlorine, such as ammonium chloride and potassium chloride, should not be applied to vegetables such as tomatoes and potatoes. After the chlorinated fertilizer is decomposed in the soil, ammonia or potassium ions are adsorbed by the soil and absorbed by the crops. To a certain extent, it will poison the plant roots, which can reduce the starch and sugar content of the product, affecting the yield and quality, and endangering the health of the consumer.
