Abstract: Orchards play a crucial role in agricultural ecosystems, sequestering more carbon per unit area than grasslands and being easier to manage than forests. However, research related to orchards is insufficient compared to that for forests. In Korea, soil carbon stock in orchards is reported in the National Inventory Report (NIR), while carbon stock from fruit trees is not included due to a lack of approach data. Previous studies have primarily developed allometric equations for apple and citrus trees, however, grapevines (Vitis vinifera L.) are distinct from other fruit trees due to their unique shape. Therefore, this study aimed to evaluate the applicability of foreign allometric equations for domestic grapevines and to develop optimal allometric equations suited for the domestic agricultural environment. Estimating grapevine biomass is essential for monitoring carbon sequestration in vineyards and is crucial for effective vineyard management and climate change mitigation.
