There is no worse idea than irrigating with salt water – they tried it, this is what happened to the plants.

If there is enough water on Earth, why are our crops increasingly thirsty? Research into the use of saline water for irrigation has led to interesting conclusions. With global climate change, the rise in average temperatures, extreme temperature peaks, as well as lack of rainfall or even massive amounts of rain in a short period, represent the biggest problems for agriculture. Irrigation would offer a solution to some of these, but the freshwater needed for this is quite limited on our planet. Let's look at the numbers! Earth is a blue planet, and it owes this to the water that covers 71 percent of its surface. Our total water supply is approximately 1.4 billion cubic kilometers, which may seem like an enormous amount, but 97 percent of it is in the oceans and seas. These are known to be high in salt (an average of 35 grams per liter), which is why they cannot be used as drinking water, industrial water, or for agricultural purposes. Recently, research was conducted on the other ...
