Plant roots play a crucial role in soil ecosystems, affecting carbon and nutrient cycling, weathering, and soil formation. Cover crops enhance soil quality by reducing nutrient loss and improving water content and organic matter. This review explores cover crop-root-soil interactions, highlighting the need for improved technologies like tomographic imaging to study these dynamics. Future studies should use metrics like LLWR and VESS for a holistic view and explore both controlled and field environments for more detailed insights into root effects on soil.
