To cope with climate change, all industry fields including agriculture endeavor to reduce carbon emissions. For calculating the amounts of carbon emission on agricultural products, establishment of LCI DB (Life Cycle Inventory DataBase) on agro-materials are needed. At this study, LCI DB on several compound fertilizers were established to supply basic informations for conducting sustainable agriculture. Average basic carbon unit for compound fertilizers was 0.86 kg CO₂-eq kg_fertilizer^-1, which ranged from 0.801 to 1.02 kg CO₂-eq kg_fertilizer^-1. With type of fertilizer, 21-17-17, 17-21-17 and 15-15-15 appeared similar value, but the rest showed about 20% higher values. As the result of life cycle impact assessment on fertilizer(17-21-17), the value of GWP (Global Warming Potential), MAETP (Marine Aquatic Eco Toxicity Potential) and HTP (Human Toxicity Potential) were 0.801 kg CO₂-eq kg^-1, 0.458 and 0.424 kg 1,4 dichlorobenzene(DCB)-eq kg-1, respectively. Basic carbon unit would be used to calculate the amounts of carbon emitted for production process of agricultural products. Also, environmental impact assessment could be served for improving the weakness in fertilizer industry through clear up the vulnerable factors.
