Are they really just dumping it? Rice paddies are usually submerged entirely. If sea water is acceptable to these plants, one could conceivably just have a canal from the ocean feeding water in (and out), with some minor dams to handle tides. Less energy used than pumping and deals with the problem of salts left behind from evaporation.
- joelthelion 8y agoWon't water evaporate and salt deposit, like in a salt pond?
- mc32 8y agoTidal mudflats don't seem to accumulate salt in the same way evaporative salt ponds do, since the water is not trapped allowing for concentration. So maybe something where tidal water is allowed to flush out overly saline water would work?
- ris 8y agoBut wouldn't that also flush out all the nutrients and nitrogen the rice needs to grow too?
- krageon 8y agoI think on hot days you are supposed to "flush" the rice fields with fresh (cooler) water anyway. The runoff then goes back to wherever (a river or in this case maybe the ocean). Assuming that is true, I imagine that means any relevant nutrients are not flushed out by this process.
