Nitrogen-fixing Leguminous Symbioses

From the reviews: "This is the final volume in a comprehensive seven volume series on all aspects of nitrogen fixation, one of the key biological processes on the planet and still a major provider of nitrogen in agro-ecosystems. ... A wide range of topics is ... presented in an easy to read style, with good clear diagrams and figures. ... This is a well-written comprehensive text, with extensive bibliographies, that will be useful to students and academics at all levels, and is to be recommended strongly." (Ron Wheatley, Experimental Agriculture, Vol. 45, 2009)
