1. It is not advisable to mix with alkaline fertilizers or apply urea at the same time. Generally speaking, in summer and autumn, urea and alkaline fertilizer should be staggered for 3 to 4 days, and in winter and spring should be staggered for 7 to 8 days. 2. Not suitable for seed dressing. Urea produces a small amount of biuret during the production process. When the content of biuret exceeds 2%, it will be toxic to seeds and seedlings and affect seed germination and seedling growth. 3. It is not suitable to irrigate immediately after application. If irrigate immediately after application or apply on dry land before heavy rain, urea will be dissolved in water and lost. Generally, water should be irrigated 2 to 3 days after application in summer and autumn, and 7 to 8 days after application in winter and spring. 4. It is not suitable to spread urea on the surface. It takes 4 to 5 days to transform before it can be used. If it is spread on the ground, most of it will be volatilized during the ammoniating process, and the actual utilization rate is only about 30%. If spread in alkaline soil and soil with high organic matter content, nitrogen loss will be faster. Deep application of urea is beneficial to the effect of fertilizer. 5. It is not advisable to apply urea too late. Applying urea too late is not conducive to the effect of fertilizer, and it is easy to cause crops to be greedy and late, so it should generally be applied 4 to 7 days earlier than other nitrogen fertilizers.
