个人简介
John Freney is a Research Fellow (formerly Chief Research Scientist) with the CSIRO, Division of Plant Industry, Canberra, Australia, and Senior Fellow with The University of Melbourne, Victoria. Initially he researched the chemical nature and biological transformations of sulfur and nitrogen in soil, and the problems caused by too little sulfur in pasture soils. He then progressed to work on problems caused by too little nitrogen in agricultural soils or too much nitrogen in the environment. His research has concentrated on the development of new techniques for assessing the transfer of gaseous nitrogen from fertilizer and animal excreta to the atmosphere, on unravelling the fate of fertilizer nitrogen applied to bananas, cotton, maize, sunflowers, flooded rice, sugar cane and wheat in Australia, China, Indonesia, Malaysia, New Zealand, and the Philippines, determining the factors controlling the emission of gaseous nitrogen compounds from plants, soils and waters, and developing management practices to improve the efficiency of use of fertilizer nitrogen and reduce deleterious effect of fertilizer use on the environment.
He has also been active in numerous international environmental projects with SCOPE; for example, he was the Co-chairman for the project on "Nitrogen Transport and Transformations – A Regional and Global Analysis" 1992-2002, and Member of Advisory Committees for SCOPE projects on "The Global Biogeochemical Sulfur Cycle", 1978-1987, "The Interactions of the Biogeochemical Cycles of Carbon, Nitrogen, Phosphorus and Sulfur", 1979-1983, "The Biogeochemical Phosphorus Cycle" 1986-1994, "Nitrogen Fertilizer Rapid Assessment Project" 2003-2004, "International Nitrogen Initiative” 2003-2011. He was also a Member of International Geosphere-Biosphere Programme (IGBP) Co-ordinating Panel on "Terrestrial Biosphere-Atmosphere Chemistry Interactions", 1989-1990, and a Member of the IGBP-IGAC Co-ordinating Committee for project on "Exchange of Methane, Nitrous Oxide and Carbon Monoxide in Mid- Latitudes".
