Critical external phosphorus requirements of pasture legumes locations
Aims

This research aimed to determine the external critical phosphorus (P) requirement (i.e. the soil extractable-P concentration required to achieve 90% of maximum yield) of a range of pasture legume species under field conditions. This information can be used as a benchmark for soil testing and soil P fertility management on farms.

Key messages
  • Ornithopus sativus (French serradella) was capable of yielding as much as Trifolium subterraneum (subterranean clover) with 30% less phosphorus (P).
  • Ornithopus compressus (yellow serradella) required 30% less P than T. subterraneum to produce the maximum yield, however its maximum yield was often lower than that of T. subterraneum
