“…Mineral–organic carbon association is widely recognized to stabilize the organic carbon against degradation in the soil environment [ [22] , [23] , [24] , [25] , [230] , [231] , [232] , [233] , [234] , [235] , [236] , [237] , [238] , [239] ]. The sorption of organic carbon by minerals is the most crucial pathway for forming mineral-organic carbon association with higher stability.…”

“…The stability of SOC is influenced by various factors, including the chemical composition of organic compounds, physical protection by soil aggregates, interactions with minerals, and environmental conditions such as temperature and moisture [1,10,11]. Furthermore, external nutrient addition can affect the SOC mineralization rate, storage, and stability of SOC [12,13]. Fertilization is a crucial aspect of modern agriculture, with the primary objective of maintaining or enhancing soil fertility and providing the necessary nutrients to achieve optimal crop growth and yield [14].…”

Soil organic carbon (SOC) pools have the potential to attain sustainable agriculture goals under climate change. External organic and inorganic nutrient inputs considerably affect SOC mineralization and SOC pools. Therefore, a laboratory-based, three-factor soil incubation experiment was conducted to investigate the impact of different exogenous nutrient additions on the mineralization and stability of SOC. The study investigated the effects of three fertilizer types (inorganic, organic, and a combination of inorganic and organic) and three rates of fertilizer addition (low, medium, and high) while considering two temperature levels (15 °C and 25 °C). At 25 °C, the application of fertilizer at a high rate significantly increased the SOC mineralization (2.84–19.97%) compared to fertilizer applied at a low rate, while, at 15 °C, different fertilizer types had no significant impact. Overall, fertilization resulted in an increase in the total potential mineralizable carbon (7.87–84.50%), while the rate of decomposition was decreased. The priming effect of inorganic fertilizer decreased over time, with the main effect observed during the initial 14 days. The addition of organic fertilizer resulted in a lesser increment in the soil activity index while simultaneously yielding a higher Q10 compared to inorganic fertilizer. Overall, the mixed application of organic and inorganic fertilizers was suggested to improve SOC stabilization and promote sustainable agricultural development.
