<p>Carbon dioxide is among the most common greenhouse gases which result in global warming. The procedure for storing carbon in soils and plant biomass that are affected by this biomass can be the simplest and cheapest solution to reduce unwanted levels of carbon dioxide. The goal of the current investigation was to ascertain the effects of <i>Eucalyptus camaldulensis</i> and fig (<i>Ficus carica</i>) on carbon storage in different soil depths. Additionally, the quantity of carbon from organic matter was determined in plant organs, i.e. in roots, stems, and leaves. The findings of this study demonstrated that the soil on which figs were cultivated had higher carbon content. Carbon sequestration occurred less in deeper soils. The soil texture where the figs were planted showed a higher percentage of sand, compared to the soil in which eucalyptus was planted and also compared to uncultivated land (control). According to the findings, carbon sequestration has a favorable and significant correlation with sand, but there is a contrast with silt. In addition, eucalyptus and figs were similar in the quantity of organic carbon preserved in their structures. In general, the maximum quantity of organic carbon was found in the stems of both plants, and the fig soil showed the best carbon sequestration (43.23 t/ha) at a soil depth of 0 to 15&#xa0;cm.</p> Graphical abstract <p></p>
