Nitrogen cycling in low input legume-based agriculture, with emphasis on legume/grass pastures

  title={Nitrogen cycling in low input legume-based agriculture, with emphasis on legume/grass pastures},
  author={Stewart F. Ledgard},
  journal={Plant and Soil},
Low input legume-based agriculture exists in a continuum between subsistence farming and intensive arable and pastoral systems. This review covers this range, but with most emphasis on temperate legume/grass pastures under grazing by livestock. Key determinants of nitrogen (N) flows in grazed legume/grass pastures are: inputs of N from symbiotic N2 fixation which are constrained through self-regulation via grass/legume interactions; large quantities of N cycling through grazing animals with… CONTINUE READING
