Mycorrhizae in Sustainable Agriculture: Proceedings of a Symposium Sponsored by Divisions S-3 and S-4 of the Soil Science Society of America, Division A-8 of the American Society of Agronomy, and Division C-2 of the Crop Science Society of America in Denver, CO, 31 Oct. 1991

U.S. agrculture faces an unprecendent problem: How to achieve long-tem sustainability in the supply of adequate levels of food and fiber for domestic and international markets, and for humanitariam aid, without degrading the natural environment or resource base, including humans and their communities, upon which agriculture depends. It is the dual nature of this challenge that markes the current situation so daunting. Agricultural scientists must discover and perfect biologically-based systems of farming that are at once productive, profitable for the indefinite future. Most conventional farmes, upon whom adoption of these systems depends, will need a greater measure of confidence in their economic and production characteristcs before making the transition top reduced input approaches.
