Critical external phosphorus requirements of pasture legumes

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.

本研究旨在明确田间条件下多种牧用豆科植物的临界外部磷（phosphorus，P）需求，即达到最高产量90%时所需的土壤有效磷浓度。该研究成果可作为农场土壤测试与土壤磷素肥力管理的参照基准。
