I'm pretty sure the irrigation system is flooding the plot. You set up berms and then periodically flood the entire plot with water. This isn't subject to the whims of nature because the flooding is done intentionally by farmers.

Rice fields are flooded as a means of weed control, but flooded fields also generate a lot of methane. There are direct seeded crop variants coming that eliminate the need for flooding.
