摘要：Phosphorus (P) is a macronutrient required by all life forms. P occurs in the environment naturally and may be introduced during farming and household activities in the form of fertilizers. Extension can play a critical role in helping to reduce commercial and household impacts of excess P in soils. Agents can help clients using education and introducing them to best management practices, including a phosphorus removal structure. It is a passive filtration system that removes P from runoff and drainage ditches before it reaches sensitive water bodies.
