Application and advantages of coated urea in agricultural production BY:Cherry

1，What is coated urea? Coated urea refers to coating the surface of urea with a layer of material to slow down the dissolution rate of urea and release it slowly in the soil. This can prevent urea from decomposing rapidly in the soil, reduce the loss and volatilization of nutrients, and achieve better fertilization effects.

2. Advantages of coated urea

（1）Reduce fertilizer loss: Coated urea is slowly released in the soil and is not easily degraded by microorganisms in the soil, effectively reducing ammonia volatilization and nitrate nitrogen loss.

（2）Increase utilization rate: Coated urea is not easy to clump, will not form a mass, can be evenly distributed in the soil, and easily contact with water, so that plants can absorb nutrients more fully.

（3）Save the number of fertilizations: Coated urea can continuously release nutrients after one fertilization, extend the nutritional cycle of crops, and reduce the number of repeated fertilizations and time costs.

 3. Application of coated urea Coated urea is a fertilizer that is very suitable for agricultural production and can be widely used on various crops. However, the planting environment and requirements of different crops vary greatly, and the application methods will also be different.

（1）Wheat: Applying fertilization on the leaves and soil 2 weeks before the heading period and 1 week before the filling period can significantly improve the yield and quality of wheat.

（2）Corn: Applying fertilization on corn combined with high-yield combinations can significantly increase the accumulation and yield of corn dry matter, and improve the yield, quality and economic benefits of subsequent crops such as wheat, beans, and oilseeds.

（3）Rice: Rice growth requires a large amount of nitrogen fertilizer. Applying coated urea in moderation can improve the nutrient utilization rate of rice, increase yield, reduce leakage loss, and save water resources. The above are only some examples of the application of coated urea. The specific application should be selected according to crop varieties, cultivation conditions, soil environment, etc.
