UWA School of Agriculture and Environment Adjunct Professor & CSIRO Principal Research Scientist in Soil Biogeochemistry Dr Mark Farrell delivered this special lecture for The UWA Institute of Agriculture titled 'Challenges of managing nitrogen and organic matter in dryland systems' at UWA Bayliss Theatre on 27 September 2022.

Dr Farrell is a biogeochemist with expertise in the interactions between organic carbon and nitrogen in soils, and the importance of these on ecosystem function and agricultural productivity. He uses radio- and stable- isotopes to track fluxes through the soil-plant-microbe interface, and spectral techniques including NMR and MIR to investigate the chemistry of pools within these systems.
Dr Farrell's research spans fundamental work to identify and isolate important functional processes through to broad applied studies where outcomes are delivered to partners in industry and government. He has studied many different land uses and ecosystems within Australia and internationally, and he seeks to find commonalities and differences in processes and function between these.
