The conversion of nitrogen gas to nitrogen compounds (N2 fixation) is essential for living organisms, and can be facilitated by industrial and natural processes. A major proportion of the naturally "fixed" nitrogen is biologically converted by micro-organisms living in symbiosis with plants. Legumes represent common hosts for a range of such diazotrophic bacteria, and constitute, next to cereals, the most important agricultural crops. Starting with first principles, this book provides wide-ranging, up-to-date information on symbiotic N2 fixation of legumes with emphasis being placed upon common bean (phaseolus vulgaris) and soybean (glycine max). Divided into five chapters, the text focuses - after an initial introduction - on processes leading to nodulation and maturation of nodules, biochemical and physiological aspects of N2 fixation, as well as the influence of the environment on symbiotic activity. Following chapters deal with techniques used for laboratory and field measurements of N2 fixation, specific physiological aspects of supernodulating legumes, and future perspectives for increasing symbiotic conversion of dinitrogen in agricultural systems.
The text gives a comprehensive overview of current theory and practice of the subject. It should be useful for graduate students, and represents a reference for scientists engaged in studies on symbiotic N2 fixation.
