This lesson focuses on the process of eutrophication; the relationship between land application of manure and soil phosphorus (P) dynamics on P delivery to surface waters; and on the P dynamics in water bodies that result in increased P available to aquatic vegetation.

This lesson describes how source factors, including soil characteristics and management practices, affect phosphorus (P) delivery to surface waters; and also discusses how crop producers can control these factors through their management practices.

This lesson addresses transport factors that may contribute to phosphorus (P) delivery to surface waters. Erosion, runoff, subsurface flow, drainage, and distance to surface water are the main factors. In some places, wind erosion may also be important. The effects of management practices on P transport are discussed, and water-related P transport processes are described in detail.
