What are the hazards of excessive application of nitrogen fertilizer?

Nitrogen is one of the important elements of fertilizer growth, but many people have such a misunderstanding that the more nitrogen fertilizer is applied, the better it will not only reduce crop yield and quality, but also produce harmful substances in the soil. So, what is the danger of excessive application of nitrogen fertilizer?

1. Excessive application of nitrogen fertilizer will cause excessive nitrogen in the soil. Excess nitrogen will form proteins with more carbohydrates, and the remaining carbohydrates will be used as raw materials to form the cell wall, which will cause the cell wall of the crop to become thinner and weaker, causing the plants to grow long, the stems are thick, and the leaves are large and thin, brittle. And easy to fold. Linyi Fertilizer Network Copyright
2. The crop absorbs too much nitrogen, the leaves are too large, the plants are closed, the ventilation and light transmission capacity are reduced, the light energy utilization rate of the crop group is reduced, the crops are vigorously breathed, the photosynthetic product consumption is increased, and the dry matter accumulation is reduced. , resulting in reduced production.

3. Excessive application of nitrogen fertilizer, the plant's ability to resist stress, susceptible to pests and diseases and freezing damage, especially susceptible to viruses. Linyi Fertilizer Network Copyright
4. Excessive application of nitrogen fertilizer will inhibit the absorption of phosphorus, potassium and trace elements, resulting in slow fruit ripening, color irregularity, deformed fruit, resulting in reduced flower bud differentiation rate, excessive vegetative growth, low fruit setting rate or no fruit setting, and fruit expansion speed. Slow, turn melons. Linyi Fertilizer Network Copyright
5. The greenhouse vegetable application of excessive nitrogen fertilizer, soil water soluble nitrogen content, easy to convert into ammonia or nitric acid gas, continuously released from the soil into the air, causing ammonia or nitric acid gas poisoning, smoked vegetable leaves.

6. Excessive application of nitrogen fertilizer will also aggravate secondary salinization of soil, so that calcium, magnesium and other nutrients in vegetable fruits are significantly reduced, and calcium deficiency and magnesium deficiency often occur. Linyi Fertilizer Network Copyright
