What to read after Nitrogen Fixation in Tropical Cropping Systems?

Nitrogen fixation by leguminous plants is especially important when farmers are trying to minimize fertilizer use for cost or environmental reasons. This second edition of the highly successful book, first published in 1991, contains thoroughly updated and revised material on the theory and practice of nitrogen fixation in tropical cropping systems. The significant research advances in the last ten years on both a fundamental and applied level are covered, including those relating to the classification and description of N2-fixing bacteria and symbioses and the processes of N2-fixation.
