>>Regarding salination: Any irrigation system that applies regular water where the land is not periodically rinsed by flooding will have salination problems due to evaporation.<<
So anything irrigated by river, aquifer, or grid-water will be accumulating trace minerals. Does that mean our current irrigation is tanking the fields b/c of trace minerals/chemicals?
>>Distilled water contains no salt or minerals, but is expensive to make.<<
What about rainwater? Does that count as distilled, at least until it gets on/in the ground and picks up trace minerals?
Also isn't there cloud/fog farming? Would that count as distilled?
And in hot areas* could someone make something like a giant airtight solar oven that would boil seawater and transfer the steam to a cooler area to recondense?
*a seaside desert, or a specialized floating facility in tropical oceans?
>>Many traditional societies prevent the problem by farming floodplains, which are regularly rinsed by floodwaters but can be easily irrigated by their adjacent waterway during the dry season.<<
Alternate crazy scheme, invert the problem and take it up to eleven with kelp farming, fish farming and oyster farming in the ocean. (Or coral farming. Is farmed coral a thing, for aquarium decorations or jewelry or other stuff?)
