Sažetak
This study evaluates the effects of different tillage systems on soil C-CO2 emissions in winter wheat and maize cultivation in two consecutive years in a conventional and conservation agroecosystem. The influence of soil temperature, soil moisture and soil organic carbon (SOC) on soil C-CO2 emissions should be investigated to gain insights into the relationships between environmental factors, soil properties and carbon fluxes during tillage. Soil C-CO2 emissions were measured on Gleysol, in a temperate continental climate in northwestern Croatia in 2023 and 2024. Three different tillage systems were involved in the study: conventional tillage (CT), conservation tillage system deep (CTD) and conservation tillage system shallow (CTS). Fertilization was uniform across all treatments. Statistically significant differences between tillage systems were not observed in either year, indicating that tillage depth did not significantly affect annual soil C-CO2 emissions under the studied conditions. However, significant differences were detected between the same treatments across different years. A weak relationship was observed between soil C-CO2 emissions and both temperature and moisture across the two years. SOC levels did not differ significantly between treatments, although some visible variation was recorded. These findings underline the need for long-term monitoring of tillage practices for developing sustainable strategies to mitigate climate change and enhance soil carbon sequestration.
