Question

Due to their extensive rice cultivation, some regions may be contributing to global warming. To what possible reason/reasons is this attributable ?
1. The anaerobic conditions associated with rice cultivation cause the emission of methane.
2. When nitrogen based fertilizers are used, nitrous oxide is emitted from the cultivated soil.
Which of the statements given above is/are correct ?

Accepted Answer

Both statements are correct.

Statement 1: Rice paddies are typically flooded, creating anaerobic (oxygen-depleted) conditions in the soil. Under these conditions, microorganisms decompose organic matter and produce methane (CH4), a potent greenhouse gas.

Statement 2: The use of nitrogen-based fertilizers in agriculture, including rice cultivation, can lead to the emission of nitrous oxide (N2O) from the soil. Nitrous oxide is another powerful greenhouse gas, released through microbial processes like nitrification and denitrification.

Since both methane emissions from anaerobic conditions and nitrous oxide emissions from nitrogen fertilizers are significant contributors to global warming in rice cultivation, both statements are correct.
