WebRICE CULTIVATION Methane is produced during flooded rice cultivationby the decomposition of organic matter in the soil. Flooded soils are ideal environments for methane production because of their high levels of organic substrates, oxygen-poor conditions, and moisture. WebRice has developed aerenchyma tissue which allows methane to escape the soil through the plant structure. This is a hollow series of tube-like structures within the plant that transport air bubbles through the rice plant. Methane that does not escape during flooding is stored in the soil and released when the water is drained away WebMethane emissions from rice fields are determined mainly by water regime and organic inputs, but they are also influenced by soil type, weather, tillage management, residues, … phosphoglycerides structure
