Short-Term Effect of Biochar on Soil Organic Carbon Improvement and Nitrous Oxide Emission Reduction According to Different Soil Characteristics in Agricultural Land: A Laboratory Experiment

Biochar application has been considered as a promising solution to address the effects of modern agriculture on climate change. However, there is lack research biochar greenhouse gas emissions based poor soils in Korean agricultural land. Therefore, this study aimed evaluate according different soil characteristics organic carbon (SOC) improvement and reduction. The incubation experiments were conducted for 49 days used feedstock (barley straw poultry manure) rates (0, 5, 10, 20-ton ha?1) four (upland, U; greenhouse, G; converted land, C; reclaimed R). results showed that SOC increased significantly all after application. increasing rate was highest soil. ha?1 treatment reduced N2O by 33.2% compared with control. Barley from soils. decreased approximately 74.5% manure biochar. Poultry improved U G soil, increased. In conclusion, barley found suppress improve addition, storage effect reduction Thus, can be potential practice improving quality decreasing domestic
