초록
Biochar is increasingly recognized as a sustainable practice to enhance soil carbon balance and reduce greenhouse gas emissions. Produced through the pyrolysis of biomass in limited oxygen, biochar has shown promise in agriculture. However, its effects on the Net Ecosystem Carbon Balance (NECB), Total Global Warming Potential (GWP), and Net GWP, especially during autumn and spring Kimchi cabbage growing seasons, require further research. This study investigates the impact of rice hull biochar on NECB, CO2, and N2O emissions during these seasons. The Biochar application rates were control=0 ton/ha, B1=1 ton/ha, B3=3 ton/ha, and B5=5 ton/ha. In autumn, Total GWP, including CO2 emissions, ranged from 3.55 to 3.93 t/ha, showing no significant impact from increased biochar application. However, Net GWP decreased substantially with higher biochar inputs, ranging from -6.84 t/ha in the control to -16.59 t/ha in the B5 treatment, indicating enhanced carbon sequestration. During spring, Total GWP increased slightly with more biochar, from 1.63 to 1.97 t/ha, but Net GWP consistently decreased, from -8.80 to –18.74 t/ha. These results suggest that while Total GWP varies seasonally, biochar improves NECB and reduces Net GWP, highlighting its potential for mitigating climate change through sustainable agricultural practices.
Abstract
Biochar is increasingly recognized as a sustainable practice to enhance soil carbon balance and reduce greenhouse gas emissions. Produced through the pyrolysis of biomass in limited oxygen, biochar has shown promise in agriculture. However, its effects on the Net Ecosystem Carbon Balance (NECB), Total Global Warming Potential (GWP), and Net GWP, especially during autumn and spring Kimchi cabbage growing seasons, require further research. This study investigates the impact of rice hull biochar on NECB, CO2, and N2O emissions during these seasons. The Biochar application rates were control=0 ton/ha, B1=1 ton/ha, B3=3 ton/ha, and B5=5 ton/ha. In autumn, Total GWP, including CO2 emissions, ranged from 3.55 to 3.93 t/ha, showing no significant impact from increased biochar application. However, Net GWP decreased substantially with higher biochar inputs, ranging from -6.84 t/ha in the control to -16.59 t/ha in the B5 treatment, indicating enhanced carbon sequestration. During spring, Total GWP increased slightly with more biochar, from 1.63 to 1.97 t/ha, but Net GWP consistently decreased, from -8.80 to –18.74 t/ha. These results suggest that while Total GWP varies seasonally, biochar improves NECB and reduces Net GWP, highlighting its potential for mitigating climate change through sustainable agricultural practices.
