Microbial Diversity and the Cycling of Nitrogen in Soil Ecosystems

  • Tohru Ueda

Nitrogen (N) is a critical element in crop production for both paddy and upland soil ecosystems. In this chapter, we describe the role of microbial biomass and its activity in Nitrogen(N) cycling supporting rice growth in the paddy soil ecosystem. We also focus on the genetic diversity of N2-fixing bacteria in rice roots. Finally, we discuss the genetic diversity of both soil bacteria, in general, and rhizobia, specifically.
