What is the primary aim of regulating fertilizer application rates in Maryland?

The primary aim of regulating fertilizer application rates in Maryland is to protect the environment from excessive nutrient runoff. This regulation is essential because when fertilizers are applied in excessive amounts, they can lead to nutrient runoff into nearby water bodies. This runoff can cause a range of environmental problems, including algal blooms, which deplete oxygen in the water and harm aquatic life, as well as leading to eutrophication.

By establishing specific application rates, Maryland aims to balance the need for crop growth with the necessity of safeguarding natural resources. These regulations help ensure that fertilizers are used efficiently and effectively, minimizing any negative environmental impacts while still supporting agricultural productivity. This focus on environmental protection is critical in maintaining the health of ecosystems, promoting sustainable agriculture, and protecting water quality.
