About

Thomas Keller is a leading soil scientist whose research centers on soil compaction, agricultural sustainability, and the physical impacts of land management practices. His work has been instrumental in quantifying the hidden risks of conservation agriculture, particularly through his highly cited study "The invisible subsoil compaction risk under no-till farming" (2025, 5 citations). This paper challenges the assumption that no-till (NT) farming—a cornerstone of conservation agriculture practiced on 15% of global cropland—is universally beneficial, revealing that NT can paradoxically increase subsoil compaction risks due to reduced natural soil loosening. Keller’s contributions bridge agronomy and geophysics, providing critical insights for balancing productivity with long-term soil health. His research has shaped policy discussions on sustainable intensification, earning recognition for its practical implications. With a citation impact that continues to grow, Keller is a key voice in understanding how modern farming must adapt to preserve soil structure for future generations.
