Phosphorus fertiliser boosts grass-legume pasture yields up to 4 years after application

Legumes can significantly boost animal diet quality and supply nitrogen for companion grasses. However sufficient numbers of well grown legumes are needed to obtain these benefits. A moderate to high soil phosphorus (P) supply is required to obtain the productivity potential of legumes suitable for clay soils (e.g. desmanthus and Caatinga stylo) (Peck et al 2015). However there is a lack of experimental data on the biomass responses of these legumes to fertiliser on low P soils.
