Background

Dr Susan Orgill has been working for NSW Department of Primary Industries as a Professional Officer (Soils) since 2005 and in her current role as a Research Officer (Soil Carbon) since 2012. Susan’s field of research relates to improved organic carbon accumulation and storage and nutrient cycling in agricultural soil, and management practices that contribute to increased economic and environmental outcomes for NSW. She completed her PhD (2016) through Charles Sturt University in which she investigated the effect of perennial pasture management on carbon accumulation in soil in southern NSW.

Susan is based at the Wagga Wagga Agricultural Institute and is a motivated and enthusiastic soil researcher, with a passion for delivering industry and farm-ready research. Susan has conceived, led and collaborated on R&D projects with scientists from a range of disciplines and in a variety of agricultural systems. She regularly communicates her research findings to a diverse range of scientific, policy and practitioner audiences, and provides expert advice in forums such as the Australian Governments Soil Carbon Technical Working Group. Susan is a full member of the Graham Centre for Agricultural Innovation at Charles Sturt University, Visiting Fellow at the Australian National University, member of the Monaro Farming Systems Technical Committee and has recently been invited to participate in an Australian Centre for International Agricultural Research (ACIAR) project in Vietnam.

Susan’s research is contributing to increases in productivity, improved resilience and sustainable use of natural resources. She is currently the Project Leader (Soils component) for the ‘Maximising access to the ERF - Rangelands Research Project’ (2016-18), and a collaborator on a number of other projects relating to soil constraints, to crop diversification and to nitrogen (N) fixation in pasture and grain legumes.
