Nitro fertilizer Ammonium nitrate and other nitrate nitrogen fertilizers are generally not suitable for application to vegetables. When the nitrate nitrogen fertilizer is applied to the vegetable field, the nitrate content in the vegetable is doubled. The nitrate is easily reduced to nitrite in the human body. The nitrite is a highly toxic substance and is extremely harmful to the human body. Chlorine-based fertilizer A compound fertilizer containing ammonium chloride and potassium chloride is called a double-chlorine compound fertilizer and should not be applied to tomatoes or potatoes. After the dichlorinated fertilizer is decomposed in the soil, the ammonium or potassium ions are adsorbed by the soil or absorbed by the vegetables. When the concentration reaches a certain level, the roots of the vegetables are poisoned, and the vegetables may be seriously killed. However, low-chlorine (referred to as potassium chloride only) compound fertilizer can effectively supplement chlorine, which can promote the growth of tomatoes and potatoes, and can be used reasonably to increase production. Double chlorine compound fertilizer, not suitable for potato application Nitrogen fertilizer Leafy vegetables should be sprayed with nitrogen fertilizer on the foliage. The vegetable leaves are sprayed with nitrogen fertilizer. After the ammonium ions are in contact with air, they are easily converted into acid ions and absorbed by the leaves. Coupled with the short growth period of leafy vegetables, it is easy to accumulate nitrate in the leaves. Therefore, avoid spraying nitrogen fertilizer on the leaf surface of leafy vegetables. Micronutrient The application of micro-fertilizers in vegetables can promote high-quality and high-yield vegetables, but the demand for trace elements in vegetables is extremely small. Excessive application of micro-fertilizer not only causes waste, but also is prone to poisoning and polluting the environment.

Vegetables must be used with caution.
Fertilizers can help farmers increase production and increase income, but bad use may cause big troubles, not only for crops, but also for toxic and harmful substances. Which fertilizers should be used with caution?
