Why is phosphorus management critical in Delaware's nutrient management practices?

Phosphorus management is critical in Delaware's nutrient management practices because it contributes to water quality issues such as algal blooms. When phosphorus is excess in water bodies, it can lead to eutrophication—a process where nutrient buildup causes excessive growth of algae. This rapid algal growth can deplete oxygen levels in the water, leading to dead zones where aquatic life cannot survive. In Delaware, where many waterways are sensitive to nutrient loading, managing phosphorus levels is essential to protect these aquatic ecosystems and maintain water quality for both environmental and human use. Properly managing phosphorus helps mitigate these harmful algal blooms, ensuring a healthier ecosystem and compliance with environmental regulations.
