20.500.12556/RUL-165968 Organic carbon sequestration potential of Slovenian agricultural soil and the impact of management practices on SOC stock Improving soil management is crucial for mitigating climate change by increasing soil organic carbon (SOC). This study addresses the question of whether Slovenian agricultural soils can increase SOC stocks and achieve the 4per1000 initiative (4p1000.org). We calculated the SOC stocks, soil carbon sequestration (SCS) potential of the fine soil fraction (<20 µm) (Csd) and the SCS potential of bulk soil for different agricultural uses in Slovenia. In addition, we conducted agricultural land management scenarios to determine a possible increase in SOC stocks. The results showed an average SOC stock of 94.7 t ha$^{−1}$ in the agricultural soils of Slovenia. High Csd values were mainly found in croplands, intensive orchards and vineyards. The Csd (0–30 cm) amounts to 16.3 Mt SOC for the entire country. In addition, our results on SCS potential were compared with similar assessments from other European countries, where the range of bulk soil SCS potential was between 0.03 and 2.8‰ SOC change yr$^{−1}$. With the current management of agricultural land in Slovenia, the SCS is almost balanced (+0.1‰). Different management scenarios showed that efficient fertilizer use, no-till, vegetation cover with biodiverse crop rotation and keeping residues on the surface lead to a significant SOC stock increase by 19.6 t ha$^{−1}$ in 20 years, which supports the 4per1000 initiative target (10.5‰). soil organic carbon sequestration potential conservation agriculture land use fine soil fraction soil management soil organic carbon sekvestracija ogljika ohranitveno kmetijstvo raba tal drobne frakcije tal obdelava tal organski ogljik v tleh true false true Angleški jezik Slovenski jezik Članek v reviji 2024-12-16 11:52:39 2024-12-16 11:52:43 2024-12-17 04:11:06 0000-00-00 00:00:00 2024 0 0 16 str. iss. 1, art. 2437574 Vol. 11 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 631.4 2331-1932 10.1080/23311932.2024.2437574 219154179 Organic_carbon_sequestration_potential_of_Slovenian_agricultural_soil_and_the_impact_of_management_p.pdf Organic_carbon_sequestration_potential_of_Slovenian_agricultural_soil_and_the_impact_of_management_p.pdf 1 7DB5B0F3E68FAB165AAFC203D0291239 95dd00559a9ae35d8d8b60aad5cec0c0d38bf42570a538a234f5d95679d91ae6 de7b4b14-bb9b-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=197303 https://www.tandfonline.com/doi/full/10.1080/23311932.2024.2437574 1 58dec282-bb9b-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=197302 Biotehniška fakulteta 0 0 0
