The highlighted paper “Representing soil landscapes from digital soil mapping products – helping the map to speak for itself” demonstrates how operational digital soil map products can enhance decision-making. By shifting focus from traditional point-based accuracy metrics to the spatial realism and visual structure of digital soil maps, this research addresses a gap in soil mapping practice. The approach ensures that soil maps meet statistical criteria but also more faithfully represent soil landscape patterns, making them more valuable and informative for end users such as land planners and environmental managers.

This study investigates interactions between soil organic carbon (SOC) and calcium (Ca). It reveals that Ca contributes to SOC stability even in acidic soils, a finding that departs from previous assumptions that Ca's role is limited to neutral or alkaline soils. It also investigates the formation mechanisms driving the association of Ca with a characteristic fraction of SOC, highlighting the importance of decomposition processes in its formation. In this work, the authors employ advanced spectromicroscopy and targeted experiments to confirm that Ca binds SOC compounds rich in aromatic and phenolic groups after decomposition, preventing their loss as dissolved organic carbon. The identification of this biogeochemical mechanism has direct implications for improving soil carbon models and guiding Ca amendment practices in agriculture, enhancing soil carbon retention and contributing to climate resilience.

Annette Eltner et al. presented a very insightful and innovative study, which is exactly what is needed in erosion modelling. The high quality of the manuscript was underlined by both anonymous reviewers who were quite enthusiastic about it. Overall, it is a manuscript worth reading for new ideas in erosion modelling.

The publication "Proglacial wetlands: an overlooked CO2 sink within recently deglaciated landscapes" is the first to report on wetlands in recently deglaciated areas. The study demonstrates that wetlands are an important component of these landscapes, but have unfortunately been overlooked in previous studies. As glaciers retreat around the globe, there has been rapid growth of research on deglaciation and its effects. This study provides timely insights that should influence future research in deglaciated landscapes emphasising the importance of including wet soils.
