Soil organic matter research in a changing world

Soils are central regulators of the Earth’s biogeochemical cycles, yet the mechanisms that influence the role of soil organic matter in soil functioning and its vulnerability to human interventions are still not sufficiently understood. In my research, I have explored the processes leading to organic matter stabilization at contrasting scales in temperate and tropical ecosystems. In this lecture, I will present my vision of how these scales need to be integrated in an interdisciplinary approach to investigate how contrasting pedoclimatic conditions, management practices, and climate change influence biogeochemical cycling. I will also present my research on the development of innovative soil amendments and sustainable management strategies to enhance fertility and increase soil carbon sequestration with the aim to strengthen resilience to global change.

I will highlight the benefits of international collaboration across continents in bringing together different viewpoints, enriching the research environment, and contributing to development. At the same time, the changing conditions we encounter when engaging with scientific knowledge, coupled with widespread misinformation, make it increasingly important to uphold scientific integrity. To nurture curiosity and inspire the next generation of scientists to seek truth with rigor and dedication, we should not entirely abandon the “old-fashioned” way of doing research. In this lecture, I will share my perspective on how soil scientists can continue to generate reliable knowledge, inform responsible management, and contribute to a sustainable future.
