I have stumbled across information (youtube videos) which claims that you can sow water by burying salt and sugar in holes in your garden. Some months later you will have water.
source: youtube search results (sorry, only in spanish ...)
I was rather surprised! Apart from the lack of any credible physical-chemical-geological explanation, the experiments are done in Colombia, seemingly in the Coffee Zone where water is not really scarce.
Wonder if anybody here has a more sound opinion on this?
Salt and sugar are hydroscopic (attract water to them) so, what that youtube is saying is obviously some one wanting you to think they are knowledgeable but in actuality they are not.
Note that they talk about "table salt" (NACL, not a good thing to add to any soil) since this is also the salt they use to melt ice and snow and is known to create dirt out of soil by killing off the microbiome.
Of course salt and sugar are hydroscopic - but once they are saturated, they will not keep attracting water. Also they will retain the water due to their hydroscopic nature. And what the videos show is that within months, you can creat creeks with this method, full of clean fresh water flowing freely ...
While I don't see how it would work, and even if it did work after salting your land, I just don't see much growing well.
In fact I am going to go so far as to say that in my personal opinion, the guy in the video is a fraudster.
It seems that hearing from some permies that it wouldn't work isn't enough to convince you.
While I think this is bad advice, you can always run an experiment.
Purchase copious amount of sugar with you hard earn cash, bury it in a hole.
Then come back a few months later and let us know if a spring has now appeared. Compare you plot to you family/friends plot nearby, both before and after.
While sugar is bad for your land, it is only temporarily, adding salt to your land just seems 1000x worse.
