Deficiencies are rare, but they are known to occur.

Chlorine is dispersed in the atmosphere from sea water (it is well established that Cl is higher in areas receiving winds from the ocean, lower in inland areas).

Ok, so to play a sort of devils advocate... I believe you, and trust your expertise (I recognize you from another forum, b/c of another thread in which you "revealed yourself" not to mention, you've always given sound advice here as well), but if chlorine is important, then how do growers that use RO, or distilled water only, not have problems with chlorine deficiencies? Or do they just not know it? Or, is it just that it's required in such a low amount, that it would take years to even recognize/see the symptoms? And what are the symptoms of a chlorine deficiency? I'm assuming that fertilizer meant to be used with RO/DI/Rain water doesn't have chlorine added... A fertilizer such as MSU brand, for example... Am I wrong in assuming that? you've got me curious!

Heheh, sorry for all the questions... Please don't take it the wrong way, I just wanna learn - and love to learn - as much as possible, and haven't (to my recollection) heard chlorine mentioned as a necessary micronutrient
