Nitrogen fixation by legumes

Webbför 20 timmar sedan · By legume: Amount of nitrogen fixed. A given legume species' range of fixation (Table 1) can be due to variations in soil and environmental conditions. For example, nitrogen fixation is likely to be less for a legume grown on soil naturally high in nitrogen because legumes will fix less atmospheric nitrogen if soil nitrogen is … WebbLegumes are able to form a symbiotic relationship with nitrogen-fixing soil bacteria called rhizobia. The result of this symbiosis is to form nodules on the plant root, within which the bacteria can convert atmospheric nitrogen into ammonia that can be used by the plant.
