ABSTRACT
PHOSPHORUS is a critical nutrient for all living organisms as a component ofmembrane phospholipids, nucleic acids, ATP, and many other biological molecules. A recent editorial addressing a potential crisis in phosphorus availability highlighted a variety of areas in which loss of this resource is a common concern [1]. Phosphorus availability plays a key role in issues of soil fertility and crop production, animal health and nutrition, as well as waste management and water quality. While many areas of the world lack sufficient phosphorus to sustain good crop yields, areas of intensive animal production experience an accumulation of excess phosphorus in soil as a result of repeated applications of phosphorus-rich manure. Runoff from pastures and croplands with elevated soil phosphorus levels can contaminate surface water and lead to environmental phosphorus pollution and eutrophication.
