Nitrogen Special Issue: summing up of papers and recommendations for future research

摘要: The 12th Australian Nitrogen Fixation Conference was the third in a series of national workshops that began 1991 and dealt with aspects nitrogen dynamics pastures croplands. conference papers published Special Issue addressed, at least part, slow progress is evident improving rate biological fixation by enhancing inoculating techniques Rhizobium strains. An important output from an analysis supply demand dryland crops, indicating less reliance on due to higher wheat yields, increased use canola crop rotations problems pulses. In 3 keynote reviews, factors affecting release biologically fixed non-legume crops were comprehensively detailed. These included frequency legumes their individual biomass rather than efficiency itself. further development models way predicting outcomes for various combinations management rotations. present trend towards fewer years phase farming Australia may reverse, resulting renewed interest ley pulse crops.
