Abstract: (1079 Views) |
Marginal areas of roads face numerous issues such as traffic congestion and environmental pollutants, which contribute to the production of greenhouse gases, particularly carbon compounds like carbon dioxide. Different ecosystems play distinct roles in absorbing atmospheric carbon. This research aims to estimate the amount of soil organic carbon storage around the Malayer-Hamadan Road across four land uses: forestation, agriculture, gardens, and rangeland. To achieve this, 10 soil samples were systematically and randomly collected at two depths (0-15 cm and 15-30 cm) in each land use area. Various soil properties, including soil texture, bulk density, organic matter, electrical conductivity, and soil pH, were measured following standard guidelines. The results indicate that at the first depth (0-15 cm), agricultural and garden uses exhibited the highest carbon storage (5.64 and 3.54 tons per hectare, respectively). In contrast, forestation and rangeland uses showed the lowest average soil carbon sequestration, with 3.07 and 2.54 tons per hectare, respectively. At the second depth (15-30 cm), agricultural and garden uses again showed the highest carbon storage (12.46 and 10.10 tons per hectare, respectively), while forestation and rangeland uses had the lowest amounts (8.42 and 6.34 tons per hectare, respectively). The correlation analysis between organic carbon quantities and soil physical and chemical characteristics revealed a significant negative relationship with soil clay percentage at the 95% confidence level, but only in agricultural use. Overall, the research concluded that agricultural and garden uses had the highest carbon reserves at both soil depths, with 18.10 and 13.64 tons per hectare, respectively.
