How to improve the utilization rate and fertilizer efficiency of urea

1.Choose the appropriate fertilization method.Different crops and soil conditions are suitable for different fertilization methods, such as sprinkling, hole application, row application, foliar application, etc., suitable fertilization methods should be selected according to the actual situation to improve the utilization rate and fertilizer efficiency of urea.Generally speaking, sprinkling is suitable for aquatic crops such as rice, hole application is suitable for deep-rooted crops such as fruit trees, row application is suitable for inter-row crops such as corn, and foliar application is suitable for foliar crops such as vegetables.

2.Avoid mixing with alkaline fertilizers.Urea is a neutral fertilizer. Mixing with alkaline fertilizers will cause the decomposition of urea to accelerate, increase the volatilization and loss of urea, reduce the utilization rate and fertilizer efficiency of urea, and also affect the effect of alkaline fertilizers.Therefore, urea should be avoided from mixing with alkaline fertilizers, such as potassium chloride, potassium sulfate, ammonium sulfate, lime, etc., if it needs to be applied, it should be separated by a certain period of time.

3.Avoid mixing with trace element fertilizers.Mixing urea with trace element fertilizer will reduce the effect of trace element fertilizer, and it will also affect the effect of urea.Therefore, urea should be avoided from mixing with trace element fertilizers, such as boron fertilizer, zinc fertilizer, iron fertilizer, molybdenum fertilizer, etc., if it needs to be applied, it should be separated by a certain period of time.

4.Avoid mixing with pesticides and herbicides.The mixing of urea with insecticides and herbicides will cause the toxicity of insecticides and herbicides to increase, cause damage to crops, and also affect the effect of urea.Therefore, urea should be avoided from mixing with pesticides and herbicides, and if it needs to be applied, it should be separated by a certain period of time.
