Methane and nitrous oxide emissions in the rice-shrimp rotation system of the Vietnamese Mekong Delta.

ABSTRACT: Rice-shrimp rotation systems are one of the widespread farming practices in the Vietnamese Mekong Delta coastal areas. However, greenhouse gas (GHG) emissions in the system have remained unclear. This study aimed to examine methane (CH₄) and nitrous oxide (N₂O) emissions from the system, including (i) land-based versus high-density polyethylene-lined (HDPE) nursery ponds and (ii) conventional versus improved grow-out ponds inoculated with effective microorganisms (EM) bioproducts. The results showed that CH₄ flux in land-based and HDPE-lined nursery ponds were 1.04 and 0.25 mgCH₄ m^-2 h^-1, respectively, while the N₂O flux was 8.37 and 6.62 μgN₂O m^-2 h^-1, respectively.
