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)...

Methane emissions from flooded rice paddies are a major source of atmospheric methane and represent significant greenhouse gas with high climate-forcing potential due to anthropogenic activities globally. For sustainable agriculture, it is necessary find effective methods for mitigating without reducing crop productivity. We investigated mechanisms reduce during cultivation by applying straw, husk biochar, humic acid, acid–iron complex, assessing gases yield over single season. The results...

Reduced tillage is a useful practice to increase soil organic carbon (SOC) stock and decrease methane (CH4) emission in rice paddy. However, the impacts of reduced on global warming potential (GWP) are generally analyzed for CH4 fluxes only during cultivation season. This study was conducted investigate effects greenhouse gas (GHG) including both nitrous oxide (N2O) SOC changes were evaluated fallow season under two different systems (conventional practice). The rate GHG emissions monitored...

This study was conducted to provide low carbon farming technique for greenhouse gases(GHGs) emission reduction in agriculture sector. It reviewed literatures on the characteristic of cultivation and its effects reduction. The GHGs were evaluated agricultural land with several practices. In rice technique, irrigation water management showed good effect paddy field. also efficiency source nitrogen supply soil improvement. intermittent 25.1% as compared continuously flooded treatment. Slow...

Intermittent drainage can reduce methane (CH4) emission from rice paddy soils, but nitrous oxide (N2O) increase. We believe that the slow released N fertilizer mitigate N2O emissions by reducing lost to environment. In this study, we tried assess influence of on effective greenhouse gas (GHG) reduction. installed three different treatments, urea (U) treatment, controlled release (CRF) and hairy vetch with (HV) treatment. The rates CH4 were monitored using closed chamber method during...

Carbon dioxide (CO2) and nitrous oxide (N2O) emissions from soil are expected to vary with type of nitrogen fertilizer used. Biochar has recently been proposed as a potential solution mitigate climate change by reducing greenhouse gas soils. Incubation experiment was conducted investigate the effect different types biochar on CO2 N2O when fertilizers used in upland soil. The treatment consisted such urea, ammonium sulfate oil cake, three biochars pear branch, rice hull soybean stalk. Soil...

Recently, biochar-related research using agricultural by-products has been actively conducted as part of a response to climate change. However, the effect reducing greenhouse gas emissions by application biochar soil type in Korea is still insufficient. Thus, purpose this study was evaluate reduction according level type. Closed chamber experiments were carried out for 42 days. The closed experiment performed applying different input amount (0, 5, 10 and 20 ton ha-1) four types (upland soil,...

Nitrous oxide (N₂O), a greenhouse gas, influences global warming 295 times more than carbon dioxide does. N inputs applied to croplands including fertilizers and organic amendments are major source of N₂O emission. However, studies on N₂O‐emanating for improving soil fertility, especially livestock manure, limited. Therefore, this study was conducted measure emission from sweet potato fields amended with manure composts over one‐year period. Three types compost, cattle compost (CMC), swine...
