Understanding differences in critical external phosphorus requirements of pasture legumes locations
Aims

This research identified the plant traits most likely to determine differences in external critical phosphorus (P) requirements (i.e. the soil extractable-P concentration required to achieve 90% of maximum yield) of pasture legume species. Understanding trait differences that affect critical P requirements of pasture legumes is important in providing confidence around field differences in external critical P requirement.

Key messages
  • Ornithopus sativus (French serradella) and O. compressus (yellow serradella) had a significantly high root hair cylinder volume compared with Trifolium subterraneum, which provides for a great phosphorus (P) foraging ability and helps explain why the Ornithopus species has lower critical P requirements than T. subterraneum.
