This is because the most active root system of corn, fertilizer absorption capacity of the strongest site is the apex. Therefore, only fertilizer topdressing in order to be fully absorbed by the use of corn.

Therefore, the top dressing corn is not as close as possible. Under normal circumstances, corn
