Continuous flooding increases CH4 emissions regardless
straw addition. Several studies have focused on management
strategies to mitigate these emissions without compromising
rice yields, such as limiting irrigation and allowing the
standing water to drain from the field. However, mitigation
options through water management can vary depending on
different factors, such as soil texture, percolation rate, frequency
of drainage, duration of dry period, and soil redox
potential (Cai et al., 1997; Majumdar, 2003; Minamikawa et al.,
2006).
