Short summary
Short summary
We assessed three soil quality indicators across Walloon Conservation Agriculture (CA) fields, accounting for practice diversity within four CA-types. Soil indicators varied significantly among CA-types. Inclusion of temporary grasslands in the crop sequence emerged as the most influential factor. Our findings show that CA effects depend on the combination of practices, highlighting the need for a systemic, context-based evaluation of soil quality.

Short summary
Short summary
Structural stability is critical for sustainable agricultural soil management. We invented a simple test to measure soil structural stability. The QuantiSlakeTest consists of a dynamic weighting of a dried soil sample in water. The test is rapid, does not require expensive equipment and provides a high density of information on soil structural properties. With an open-access programme for data management under development, the test has strong potential for adoption by a large community of users.

Short summary
We developed a framework using rates and 14C-derived ages of soil-respired CO2 and its sources (autotrophic, heterotrophic) to identify carbon cycling pathways in different land-use types. Rates, ages and sources of respired CO2 varied across forests, grasslands, croplands, and managed peatlands. Our results suggest that the relationship between rates and ages of respired CO2 serves as a robust indicator of carbon retention or destabilization from natural to disturbed systems.

Short summary
Soil amendment with artificial black carbon (BC; biomass transformed by incomplete combustion) has the potential to mitigate climate change. Nevertheless, the accurate quantification of BC in soil remains a critical issue. Here, we successfully used dynamic thermal analysis (DTA) to quantify centennial BC in soil. We demonstrate that DTA is largely under-exploited despite providing rapid and low-cost quantitative information over the range of soil organic matter.
