This book traces the global phosphorus cycle from weathering and the cycling of phosphorus in soils through phosphorus fertility management in agroecosystems and the resultant global transfers of phosphorus to its impact on eutrophication of inland, estuarine and marine waters. Policy issues and options of phosphorus management for global food security and pollution control are outlined as well as low input management and reclamation of infertile tropical soils.
Closing the Cycle; Global Transfer of Phosphorus in Fertilizer Materials; Phosphorus Fertility Management in Agroecosystems; Heavy Metal and Radionuclide Contaminants; Rehabilitation of Anthropic Savannah; Phosphorus Transfer from Terrestrial to Aquatic Ecosystems; Riverine Transport and Transformation of Phosphorus; Nutrient Limitation of Phytoplankton and Eutrophication of Estuarine and Marine Waters.
