Effect of Long-Term Fertilization on C Mineralization and Production of CH sub(4) and CO sub(2) under Anaerobic Incubation from Bulk Samples and Particle Size Fractions of a Typical Paddy Soil
Effects of long-term fertilization on carbon (C) mineralization and production of methane (CH sub(4)) and carbon dioxide (CO sub(2)) under anaerobic incubation were examined. It was observed that CO sub(2) production predominated over CH sub(4) from C mineralization from both bulk samples and the si...

description | Effects of long-term fertilization on carbon (C) mineralization and production of methane (CH sub(4)) and carbon dioxide (CO sub(2)) under anaerobic incubation were examined. It was observed that CO sub(2) production predominated over CH sub(4) from C mineralization from both bulk samples and the size fractions. The CH sub(4) production played a predominant role in the total global warming potential (GWP) under all treatments. Higher C mineralization and CH sub(4) production with a higher metabolic quotient under chemical fertilizer (CF) implicated a vulnerability of soil functioning of greenhouse gas (GHGs) mitigation in the paddy receiving chemical fertilizers only. The results concluded that rational organic amendments should be undertaken for mitigating the climate change. |
