What issues need attention when urea production surges?
How can urea application improve utilization efficiency? Please guide deep application. Whether urea is used as a base fertilizer or a top dressing, it should be applied deep and covered with soil, with an application depth of 10-12 cm being appropriate. Deep application of urea can significantly improve utilization efficiency. According to experiments, when urea is surface-applied or shallow-applied at 2-3 cm, the utilization rate is only 30%; at an application depth of 5 cm, the utilization rate is 45%...
