Abstract: The objective of this study was to estimate how soil organic carbon influences winter wheat yield in the South Pannonian Basin. The treatments evaluated were: fertilized 3 year and 2 year crop rotation, fertilized wheat monoculture and unfertilized 3 year and 2 year crop rotation in the 38 years of continuous cropping (1970-2007). These treatments showed a declining trend of soil organic carbon in the 0-30 cm soil layer, respectively. On average, the plow-layer of the treatments lost 10% of soil organic carbon found at the beginning of the investigated period. The plow­layer of the unfertilized treatments reached a possible soil organic carbon threshold (1.16%) after balance on decomposition and formation was observed. We found that soil organic carbon preservation coupled with proper management such as crop rotation and fertilization is important for preserving soil productivity, and when soil organic carbon increases it could benefit winter wheat yield. Obtained results are valuable for developing a sustainable cropping technology for winter wheat and soil conservation.
