BOOK OF ABSTRACTS 205 IHSS&IWA26 / BRNO / CZECHIA / 23–28 August 2026 Hall A Poster Session / Soil Organic Matter, Caustobiolites, and Biochar P2.10 Soil Health and Organic Carbon Monitoring for Sustainable Agriculture and Environmental Recovery Liudmyla Vasylenko President, Association of Innovation Laboratories (Ukraine) Director, Prime Lab Tech Email: L.vasylenko@plt.land Soil degradation and the decline of soil organic carbon (SOC) represent critical challenges for sustainable agriculture, ecosystem stability, and climate mitigation. Globally, more than 33% of soils are degraded, while agricultural systems have experienced substantial losses of SOC, in some cases exceeding 50%. These challenges are particularly acute in Ukraine, which hosts a significant share of the world’s chernozem soils and is currently exposed to intensive agricultural use and largescale environmental disturbances. This study presents an integrated framework for soil health assessment and SOC monitoring based on advanced laboratory diagnostics and harmonized analytical methodologies. The approach combines physicochemical soil analysis, nutrient profiling, and contamination assessment with standardized data processing to ensure comparability and reproducibility of results. The proposed system enables high-resolution characterization of soil properties and supports the development of site-specific, datadriven management strategies. Particular attention is given to disturbed environments, where soil structure, fertility, and contamination require targeted restoration approaches. The results indicate that the integration of laboratory data with digital tools significantly improves soil fertility assessment and supports carbon sequestration, with a potential range of approximately 0.3–1.0 t C/ha/year depending on management practices. The Ukrainian case highlights the need for scalable and interoperable soil monitoring systems and demonstrates their relevance for European soil health and climate objectives. Keywords: soil health, soil organic carbon (SOC), sustainable agriculture, Ukraine, soil monitoring, environmental recovery, carbon sequestration, datadriven agriculture
