Improving Soil Health

Dr William Horwath is a Distinguished Professor of Soil Biogeochemistry and J. G. Boswell Endowed Chair in Soil Science at the University of California-Davis, USA, where he is also Faculty Director of the Sustainable Agriculture and Food System undergraduate major. He is the current chair of the Department of Land, Air and Water Resources at the university. Professor Horwath is Editor of the Soil Science Society of America (SSSA) Journal and is a Fellow of the SSSA. He has published widely on measuring and improving soil health and climate impacts on ecosystems.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.
