Rice cultivation is taken in flooded soil condition. This creates an anaerobic environment and harbours different group of anaerobes. The continued submergence of soil provides a reducing environment and effects a build-up of anaerobic ecosystem in which two unique processes namely methane emission and reductive transformation of nitrogen occur. But the role played by specific group of anaerobes with respect to nitrogen transformation is still obscure. A study was undertaken to assess the different groups of anaerobes in nitrogen transformation in flooded rice soils. |
