John Piltz

Research interests

  • Integrated crop and livestock production systems in southern NSW
  • Conserved forages to improve productivity and sustainability of livestock industries
  • Cereal and cereal/legume forage crops for hay and silage production
  • New legume species in mixed farming systems
  • Effect of ensiling on weed seed viability
  • Forage production and conservation as part of Integrated Weed Management
  • Feed quality evaluation


John is based at the Wagga Wagga Agricultural Institute and conducts research of relevance to southern farming systems, livestock nutrition and forage conservation. He currently supervises NSW DPI’s component of two projects: ‘Addressing Herbicide Resistance – Options and Non-Chemical Approaches for Mixed Farmers’ and ‘Developing profitable dairy and sheep meat production systems in Central Tibet’. He is also involved in the supervision of post-graduate students and provides technical support to NSW DPI’s Feed Quality Service.
