What is the maximum amount of soluble nitrogen allowed in a single application?

The maximum amount of soluble nitrogen allowed in a single application is a regulation designed to prevent nutrient runoff and protect water quality. In Maryland, the established limit is 0.7 lbs of soluble nitrogen per 1,000 square feet in a single application. This regulation is important because it helps to minimize the risk of nitrogen leaching into groundwater and the potential for nutrient pollution in waterways. By adhering to this limit, applicators can promote effective fertilization while mitigating environmental impacts. Understanding these guidelines is fundamental for maintaining healthy ecosystems and complying with state regulations regarding fertilizer application.
