MITIGATION STRATEGY TO CONTAIN METHANE EMISSION FROM RICE-FIELDS

摘要

Methane is primarily a biogenic gas, which is implicated in global climate change. Among all the sources of methane emission, paddy fields form the most dominant source. An experiement was conducted with a common paddy crop (Oryza sative var. Vishnuparag) by amending the soils with different organic manures and biofertilizers with a view to find out an inexpensive strategy to mitigate methane emission from the rice-fields. The results revealed that there was a seasonal change in the CH_4 flux, registering a peak at heading stage in all treatments.
