Some chemical fertilizers can increase their quality and yield after being applied to vegetables, but some fertilizers can increase the yield after application to vegetables, but they will pollute vegetables.
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 multiplied, and the nitrate is easily reduced to nitrite in the human body, and the nitrite may cause harm to the human body.
Chlorinated fertilizers such as ammonium chloride and potassium chloride are not suitable for use in crops such as tomatoes and potatoes. After the chlorine-containing 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.
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. In addition, the leafy vegetables have a short growth period, and it is easy to accumulate nitrate in the leaves. Therefore, avoid spraying nitrogen fertilizer on the leaf surface of leafy vegetables.
