Is it correct that enhanced efficiency fertilizer may not be applied after a specific date?

Enhanced efficiency fertilizers are designed to minimize nutrient losses to the environment, especially in water bodies, through their controlled release formulation. The application of these fertilizers is subject to specific timing regulations to prevent nutrient runoff, particularly in the fall and winter months when the potential for such runoff is highest due to precipitation and snowmelt.

In Maryland, there is a regulatory date after which enhanced efficiency fertilizers should not be applied, specifically after November 15. This cut-off is intended to protect water quality by reducing the risk of excess nutrients entering waterways during times when plants are less able to uptake them due to the colder weather and dormancy of many crops. This timing ensures that the application of fertilizers aligns with their intended effectiveness while also considering environmental protection.

It’s important to recognize that while some fertilizers may have different application windows, this specific restriction applies to enhanced efficiency fertilizers, thus confirming that the correct answer is indeed that they may not be applied after November 15.
