IHSS&IWA26 / BRNO / CZECHIA / 23–28 August 2026 BOOK OF ABSTRACTS 204 Poster Session / Soil Organic Matter, Caustobiolites, and Biochar Hall A P2.9 Soil Health and Organic Carbon Monitoring for Food Security Chornoivan Yuliya1 1 PRIME LAB TECH LLC, Ukraine Contact information plt17025@gmail.com Soil quality and soil organic carbon (SOC) content are key factors determining land fertility, crop yield, and overall food security. Loss of organic carbon in soils leads to reduced productivity, degradation of soil structure, lower water-holding capacity, and diminished nutrient retention, all of which threaten the sustainability of agricultural systems. In Ukraine, which hosts extensive areas of fertile chernozem soils, these challenges are particularly critical due to intensive land use, large-scale environmental disturbances, and ongoing climate pressures. This study presents an integrated, multi-parameter approach for soil health assessment and SOC monitoring, combining detailed physicochemical analysis, nutrient profiling, contamination assessment, and standardized data processing to ensure comparability and reproducibility of results across sites. Particular attention is given to critical soil indicators, including SOC content, soil texture and structure, pH, nutrient balance, and crop productivity potential, which together provide a comprehensive picture of soil fertility and its capacity to support sustainable agriculture. High-resolution data analysis enables the development of sitespecific, evidence-based management strategies that optimize productivity while enhancing carbon sequestration. Depending on applied agricultural practices, potential SOC gains range from approximately 0.3 to 1.0 t C/ha/year. Moreover, the integration of laboratory findings with digital decision-support systems allows real-time monitoring and adaptive management, strengthening food security by ensuring consistent and resilient crop production. This framework demonstrates the value of data-driven soil management for sustainable agriculture and environmental recovery, particularly in regions with highly productive yet vulnerable soils.
