Talk:Saline water

From Wikipedia, the free encyclopedia

[edit] 2500 PPM

What does it mean by "in Colorado, water having up to 2,500 ppm of salt is used for irrigating crops." Is that a requirement from somewhere? Or is that just what's available?

[edit] Answer

Well, it would be sort of obvious to me that water up to 2,500 ppm of salt is usable because anything higher would make the plants die...
