- Abstract:
- This project seeks to assess the impact of low inputs of SO4 2- in acid rain on CH4 emission from rice agriculture. Large inputs of SO4 2- in fertilisers (10 2- -10 3 kg S/ha) are known to suppress CH4 emission from rice paddies. However, recent research by the Open University has shown that in natural wetlands only a fraction of this amount (25 kg S/ha/year) applied as small weekly pulses over a year to replicate inputs from acid rain can have the same effect, reducing CH4 emissions by 40%. Rice paddy agriculture is a major source of anthropogenic CH4, which is thought likely to increase as the demands of a growing population in Asia are met. This region is also rapidly industrialising with large increases in S pollution predicted over the next 30 years. We propose to evaluate whether this SO4 2-/CH4 interaction has the potential to counteract the likely increase of a powerful greenhouse gas.
