| Soil carbon storage is considered an important climate change mitigation strategy as it represents a major carbon storage reservoir in the global carbon cycle. Ministry for Food, Agriculture, Forestry and Fisheries (MIFAFF) set up the Agricultural Environment Conservation Program and agricultural practices to promote soil carbon storage are included as important activities. However, there is no established methodology to quantify the performance of agricultural practices that can enhance soil carbon storage. In this study, a methodology and tool were developed to quantify changes in soil carbon storage related to conservation actions. First, cropland was divided into rice paddies, agricultural fields, and perennial/tree crops, and agricultural activities were systematized considering domestic agricultural circumstances. No-till farming, cultivation of green manure, crop residue return, compost application, and biochar input were considered. Next, default factors of IPCC (Intergovernmental Panel on Climate Change) guideline and domestic research papers were reviewed to find the relevant effects of different activities on soil carbon storage. Finally, a spreadsheet for calculating changes in soil organic carbon stock was built using Microsoft Excel. The developed method was applied to Sangju-si and Boryeong-si, which joined the Agricultural Environment Conservation program, and the total increase in soil carbon storage in 20 years was calculated as 255.0 ton C and 356.8 ton C, respectively. The methodology and soil carbon stock calculator established in this study will be able to more accurately reflect the domestic situation if country-specific emission factors are incorporated in the future. | |
