Detection, monitoring and management of soil structure and compaction
Friday November 26th, 2021 9:15-12:30
Please find the full recorded oral presentations and posters and abstracts here.
We explored how to characterize and monitor soil structure and treat the challenges around the widespread problem of soil compaction and soil structural loss: prevention, detection, monitoring and management.
Soil compaction is one of the main physical threats to soil and largely results from the use of agricultural machinery, often in combination with wet soil. Halting soil degradation was put forward by the United Nations as one of the 17 Sustainable Development Goals (SDG 15). The phenomenon not only has negative consequences for rooting, nutrient uptake and consequently crop yield, but also compromises good water management. A compacted soil, after all, prevents the proper drainage of water in wet periods and makes it difficult for moisture to rise from deeper layers in dry conditions.
During this thematic day, we explored ongoing research on prevention, detection, monitoring and remediation of soil structural loss and compaction and its underlying processes.
Keynote talk by Alejandro Romero-Ruiz / Methods for Field-Scale Characterization of Soil Structure
Alejandro is a postdoctoral scientist at Rothamsted Research (UK). He obtained his PhD from the University of Lausanne in 2021, in which he studied the impact of soil compaction on soil hydraulic and mechanical properties at the plot scale by combining hydrological modeling and field monitoring of geophysical data. His current research focuses on the impacts of soil compaction in grasslands resulting from animal treading.
