Phosphorus (P) is an essential nutrient for growth of crops and aquatic vegetation and often needs to be applied to land for optimal crop growth. Land application of P as animal manure, biosolids (sewage sludge), and mineral fertilizer can increase the risk of P pollution of freshwater.

The movement of P from agricultural land to surface and ground water is a complex process involving multiple pathways. Phosphorus moves into surface freshwaters dissolved in runoff water and attached to particulate matter eroded from the land. Recently applied P is particularly prone to losses and is affected by factors such as the form of P applied, the time since application, and the placement. The factors contributing to P loss from agricultural land to surface waters are commonly grouped as source (site and management) factors and transport factors.

This publication is targeted to U.S. EPA Region 7 comprised of Iowa, Kansas, Missouri and Nebraska.
