Research interests

  • Pasture agronomy and species evaluation
  • Acid soil management


Richard Hayes joined NSW Department of Agriculture* in 2000. He is an applied researcher with experience in conducting field- and glasshouse-based research on a broad range of issues relating to pasture and soil health relevant to systems in southern NSW.

Richard led the NSW node of the EverCrop project; a research initiative conducted across southern Australia examining the opportunities and challenges of integrating perennial plant species in cropping systems. He also led the national EverCrop Carbon Plus project examining the opportunities for perennial plants to replenish soil carbon reserves in cropping soils.

Richard is one of the few researchers in Australia actively pursuing research on perennial grains technology, following the first evaluation of perennial wheat material under field conditions in the Cowra region.

Richard’s most recent project is examining the opportunities to develop more phosphorus-efficient pastures for the grazing industries. This project will examine the opportunities to develop more P-efficient pasture species, such as serradella, as well as examining traditional species such as subterranean clover to identify cultivars that perform better on lower nutrition soil.

*NSW Department of Primary Industries was formed on July 1, 2004 through an amalgamation of NSW Agriculture, NSW Fisheries, State Forests of NSW and the NSW Department of Mineral Resources.
