What should be noted when applying urea? Please advise, thank you very much. Urea has a high nitrogen content, long-lasting fertility and is easy to apply, so it is very popular with farmers. To give full play to the role of urea, the following points should be noted during use: do not broadcast it on the soil surface: when urea is broadcast on the surface, at normal temperature it takes 4-5 days of transformation before it can be...
How to apply urea in summer? Please advise and explainWhen urea is used as a topdressing in summer, attention should be paid to covering it with soil or irrigating in time. Because the temperature is very high, urea transforms quickly, and the product of urea transformation is ammonium carbonate, which is even more unstable than ammonium bicarbonate, commonly known as "qi'er fertilizer," and will produce large amounts of ammonia. If the urea is not buried in the soil, or is broadcast on the surface without immediate watering, the consequence of ammonia volatilization will burn the leaves; in severe cases, the plant leaves will look as if they have been boiled in water. Even if the ammonia volatilization does not burn the seedlings or leaves, the nitrogen loss it causes will also pollute the environment and reduce the utilization rate.
