Monday, August 16th, 2021: Key unresolved questions about the chemistry and structure of humic substances

Dr. Maria De Nobili is Full Professor of Soil Science and Environmental Chemistry and head of the Environmental Soil Functionality group at the Department of Agrifood, Environmental and Animal Sciences of the University of Udine (Italy) Her main scientific interests have been soil organic matter dynamics and soil biological properties. Her approach to the study of humic substances has aimed to investigate links between humification trends and soil biological activity considering pedoclimatic conditions with particular attention to submergence and agricultural soil management. Her present research focuses on the consequences of plant biological invasions on soil properties and the redox state of humic substances in tidal soils and sediments and their relationship with sulfide and toxic metals immobilization. Other interests include the composting of sewage sludge and organic wastes (two patents) and their use in agriculture, particularly in relation to methane emission/oxidation in soil.

She served in the Board of Directors of the IHSS from 2000 to 2008 and as President of the Society from 2004 to 2006. She was Honorary Chairperson of Humic Substances Seminar VII (Boston, 2002) and Chairperson of the scientific committees of the 12th and of the 13th IHSS international conferences held in Sao Pedro (Brazil) in 2004 and in Karlsruhe (Germany) in 2006.
