GLIN==> Michigan Chapter SWCS Seminar Reminder

A Matter of Balance – Peak Phosphorus: Balancing Demand, Supply and the Environment 

Wednesday, March 10
8:30 a.m.- 4:30 p.m.
Kellogg Hotel and Conference Center, Michigamme Room, East Lansing, Michigan
Sponsor: Michigan Chapter, Soil and Water Conservation Society
“Peak phosphorus” is the point at which the mining of phosphorus will peak and begin to decline. It is associated with increasing cost of extraction, decreasing availability and increasing costs to the consumer. There is no substitute for phosphorus. Current sources of readily available mined phosphorus will be exhausted in 50 to 130 years, according to many sources.
Phosphorus is one of the key essential elements in modern agriculture. Yet phosphorus, along with nitrogen, is being discharged into surface waters from many sources and contributes to high phosphorus levels in lakes and rivers in Michigan and elsewhere. These high nutrient levels can result in major environmental damage, such as the dead zone in the Gulf of Mexico.
This seminar will introduce the issue of peak phosphorus; review the phosphorus cycle and explore how phosphorus behaves in the environment, including the pathways for waste or loss; consider how phosphorus behaves in the food chain; examine the soil and water quality relationships of phosphorus; and consider management practices that can reduce loss of this resource and the resulting environmental impacts.
