Aims

This paper reports results from previous reserach and some recent findings on inputs on fixed N2 by different legumes routinely measured. The project examines the effect of legumes or canola break crops on subsequent cereal productivity in cereal-dominated cropping systems.

Key messages
  • The choice of legume species and management were found to influence the amount of nitrogen fixed by both crop and pasture legumes byaffecting either legume reliance upon N2 fixation for growth or changes in dry matter accumulation.
  • Medium to high soil mineral N concentrations at sowing appeared to suppress N2 fixation by field pea more than lupins or faba beans.
  • Pulse legumes grown for grain generally result in lower net inputs of fixed N.
  • Available soil N following either legume crops or pastures can represent an additional 40 to 90kg N/ha in the 1st year.
  • The increased N uptake by the 1st wheat crop grown after legumes was equivalent to 27-40% of N in the previous year's legum residues.
