Which of the following is a common practice regarding nitrogen application in the fall?

The correct choice emphasizes the importance of timing when it comes to nitrogen application, particularly in the fall. No applications after November 15 are recommended to minimize the risk of nutrient runoff and leaching into groundwater during winter months. Fall applications, if made too late, can lead to nitrogen being lost to the environment rather than being utilized by the plants, which can cause pollution and inefficiency.

This practice aligns with environmental management strategies aimed at protecting water quality and ensuring that nutrients are applied when they are most beneficial for plant uptake. The restriction on fall applications after a specific date helps manage the potential impact on water bodies and adheres to best management practices.

Other potential practices regarding nitrogen application either lack specificity or encourage practices that could lead to adverse environmental impacts, particularly when applied without regard to the risks associated with timing and seasonal weather patterns.
