We discuss results from controlled environment studies including mesocosms, grazing experiments and long term field experiments which show how biological N2 fixation in legume based systems is tightly coupled to the N demand at scales ranging from the individual plant to the grassland ecosystem. We further test the consequences of this hypothesis of a feedback regulation of biological N2 fixation by N demand with a mechanistic model linking plant community dynamics and ecosystem functioning… CONTINUE READING
