As an efficient nitrogen fertilizer, urea has a wide range of application prospects and values. When using urea, you need to pay attention to the following:
1.Urea is easy to decompose in a high-temperature environment, so care should be taken to avoid exposure to the sun and high-temperature environments when using it. This is because the nitrogen in urea decomposes into ammonia at high temperatures, resulting in reduced fertilizer efficiency. Therefore, when using urea, it needs to be stored in a cool, dry, ventilated place, away from fire and water sources to ensure that it is stable and effective.
2.Urea should be kept in a cool, dry, ventilated place and away from fire and water sources. This is because urea may be affected by factors such as moisture and temperature during storage, causing it to decompose or fail. Therefore, when using urea, it needs to be stored in a cool, dry, ventilated place and avoid contact with water to ensure its quality and effectiveness.
3.Urea should not be mixed with fertilizers containing acidic substances to avoid reducing fertilizer efficiency. This is because the nitrogen in urea forms nitrogen in an acidic environment, resulting in reduced fertilizer efficiency. Therefore, when using urea, it is necessary to avoid mixing with fertilizers containing acidic substances to ensure its fertilizer efficiency.
4.Urea should not be applied to saline-alkali land and soil that has been used with lime, otherwise it is easy to cause soil compaction and salinization. This is because the nitrogen in urea forms ammonia in an alkaline environment, resulting in reduced fertilizer efficiency. Therefore, when using urea, it is necessary to avoid applying it to saline soils and soils that have already used lime to ensure its fertilizer efficiency.
5.The amount of urea used should be appropriately adjusted according to factors such as soil type, crop type, growth stage, etc., so as not to cause fertilizer damage. This is because the nitrogen in urea has a low solubility in the soil, and excessive use can easily lead to fertilizer damage. Therefore, when using urea, it needs to be adjusted appropriately according to factors such as soil type, crop type, growth stage, etc., to ensure its fertilizer efficiency and safety.
6.Attention should also be paid to the use of urea, generally using furrow application, hole application or sprinkling, etc., do not spray urea directly on crops. This is because the nitrogen in urea has a low solubility in the soil and can easily cause fertilizer damage if sprayed directly on crops. Therefore, when using urea, it is necessary to use furrow application, hole application or spreading application to ensure its fertilizer efficiency and safety.
