  • Research has increasingly identified phosphorus pollution from municipal, industrial, and agricultural sources as a major threat to water quality.
  • Pollution risk increases with higher levels of soil phosphorus; however, site-specific soil, hydrologic and management characteristics also have considerable influence on water pollution risk. Surface waters in Alberta are extremely sensitive to further P enrichment.
  • A desirable long-range goal for Alberta is a balanced nutrient management approach to land application of all nutrient-bearing materials; however, a site-specific approach to soil P management would be suitable for addressing the more immediate need to protect water quality.
The report also covers background information on P in soils and in organic products applied to soils, including manure. It identifies the impacts of excess soil P levels, how high soil P levels can degrade water quality, and it discusses methods used in other areas for controlling P levels.
