Background

Ashley Webb is a Senior Research Scientist with extensive experience researching soil and water management issues. He leads the soil research and development activities of the Soils North sub-unit to support sustainable and profitable agricultural and forest industries. Ashley joined Agriculture NSW in 2013 having spent the previous 12 years employed by Forests NSW in various soil and water research and management roles. Ashley has collaborated with a number of Australian and International scientists from several earth and environmental science disciplines. He was a 2011 Gottstein Fellow, is a Fellow of the Institute of Australian Geographers and holds an adjunct research position within the Australian Centre for Agriculture and Law at the University of New England. Ashley has over 40 refereed publications and supervises a number of PhD and Masters students.
