Dr Richard Hayes is a Senior Research Scientist at the NSW Department of Primary Industries, Wagga Wagga Australia. He has over twenty years experience as a farming systems researcher, specialising in acid soil management, perennial agriculture and species evaluation. Dr Hayes has completed three post-graduate degrees all involving field research on acidic soils, including an examination of the response to lime of self-regenerating annual legumes, the effect of lime on soil water dynamics under perennial forages and the spatial variation of soil pH as it relates to the drill row.
