Francesca Cotrufo is Professor and Associate Head at the Department of Soil and Crop Sciences, and Senior Scientist at the Natural Resource Ecology Laboratory, at Colorado State University.  She earned B.Sc. from the University of Naples, Italy and Ph.D. from Lancaster University, UK. Dr. Cotrufo is internationally recognized for her work on litter decomposition and soil organic matter formation, and for the creative use of isotopic methodologies in these studies. More recently her team developed an integrated measurement-modelling approach to further improve the understanding of the mechanisms and drivers of formation and persistence of soil organic matter, and better predict soil organic matter changes in response to global environmental changes, disturbances, and management practices. Her overall goal is to contribute to the design and development of a research and decision support approach to facilitate soil health improvements and climate change mitigation and adaptation. She is subject editor of the journal Global Change Biology. To date she has published over 100 peer reviewed articles and several book chapters.

Presentation: Improving understanding and forecasting of Soil Organic Matter dynamics to transform challenges into opportunities

Prof. Dr. Dr. h.c. Ingrid Kögel-Knabner studied geoecology at the University of Bayreuth, where she also obtained a doctorate in soil science (1987) and habilitation (1992). In 1991 she received a professorship for soil science and soil ecology at the Ruhr-Universität Bochum. Since 1995 she serves at the Chair of soil science of the Technical University of Munich TUM. Since 2011 she is Carl von Linde Senior Fellow at TUM Institute of Advanced Study. She is member of the Editorial Board of several high-impact soil science journals. Since 2015, she has been on the list of “Highly Cited Researchers”, belonging to the most cited scientists in the world.

Ingrid Kögel-Knabner’s work is dedicated to understanding the formation and properties of soil organic matter as a major component of soils, and its central role in the terrestrial carbon cycle. Her work focusses specifically on soil structure and the biogeochemical soil interface formed by the interaction of organic matter with the soil mineral phase. The challenge to be coped with is the transition of methods which have been designed and developed for pure systems to the extremely complex, often amorphous natural materials found in soils. By applying a spectrum of sophisticated techniques (solid-state 13C NMR spectroscopy, chemolytic methods with gas chromatography-mass spectrometry, stable isotopes, radiocarbon dating, scanning electron microscopy SEM, NanoSIMS) the elucidation of soil organic matter structure, interactions and turnover can be brought a step forward.

Soil monitoring and mapping can be achieved through a number of approaches. My work focusses on optimising sensing approaches (remote sensing, soil spectroscopy) and developing new methods (soil profile image analysis). The integration of sensory data with existing, legacy survey data allows us to carry out improved mapping of soil properties. Much of my work in this area focusses on soil carbon, particularly in organic soils, in terms of primary soil health properties (carbon, texture, bulk density, pH).

Presentation: Organic amendments: opportunities & challenges in stressed agricultural environments

Budiman Minasny is a professor in Soil-Landscape Modelling at the University of Sydney. His research and contribution to the discipline of soil science have been on discovering the causes and controls of soil distribution over space and time. This knowledge is crucial for soil security which is central to managing climate change, food, water, energy security and maintaining biodiversity. He works on theoretical and physical models to explain soil-formation processes and to understand why soil varies so much in the landscape. He also employs empirical approaches to gain insight from soil data and unravel the complexity of soil variation in the real world. His interest in soil organic matter research is on assessing and monitoring soil carbon stocks effectively. Better land management that can maximise the soil carbon sink and continuously improve productivity will help alleviate many land degradation processes.
