n the context of contemporary agriculture, there is an imperative to curtail greenhouse gas emissions, including carbon dioxide, while concurrently enhancing the stability of organic caarbon within the soil. The objective of this study was to ascertain the impact of digestate augmented with biochar and zeolite on the emission of carbon dioxide from the soil and the process of organic carbon mineralization. The experiment was conducted on soils with three distinct variants: a control group (without additives), a group receiving digestate and biochar, and a group receiving digestate and zeolite. The study’s findings demonstrated that both biochar and zeolite effectively curtailed the flux of carbon dioxide (CO₂) in comparison to the control soil. An augmentation in the total organic carbon and soluble organic carbon content was observed in the plot with digestate and biochar, while in the plot with digestate and zeolite, the forms of this carbon were stable. Kinetic models of carbon mineralization indicated a reduction in its decomposition in the plots with additives. The findings of this study substantiate the efficacy of the amalgamation of digestate with biochar and digestate with zeolite as a strategy to curtail carbon losses in soil and mitigate CO2 emissions. Nevertheless, further research is warranted to optimize dosages and ascertain the long-term implications of employing these additives in diverse soil conditions.
