Managing Global Resources for a Secure Future

Many soils in the developed countries with intensive animalproduction are sufficiently saturated with phosphorus (P) dueto the historic applications of animal manures. This hasresulted in elevating soil test P (STP) to above agronomiclevels, which limits farmers to effectively recycle manures. Inthese settings, there is increased regulatory pressure toreduce manure applications. This session seeks presentationsthat articulate innovative and transformative solutions toeffectively manage future manure applications in P saturatedsoils, suggest ways to manipulate STP that decreases P loss,and recommend strategies to better predict decline in STP andP loss to water bodies.
