I will start by saying, I do agree with Chef overall, but I am rather OCD when it comes to terminology and its correct use. Apologies, my dear chef, but I am going to be a bit of a nit picker here (chalk it up to the teacher in me

Metals are not salts. Rather they constitute an important part of the make-up of salts. (Salts are the result of ionic bonding between a metal atom(s) and a nonmetal atom(s) for anyone out there who might care.)

Nitrogen and phosphorous are not salts, they are both nonmetals. Potash (K2
O) is indeed a salt as it is potassium bonded to oxygen. (Potash is typically used as a source of potassium in many fertilizers.)

Pure potassium is even more fun.

As is the case with so many things in life. Take bacon for instance .....
But seriously, it is a very common truism. For example, some sodium is important for proper functioning of the human body. Too much results in high blood pressure and other issues.

Interestingly, at least to me, it is also poisonous to many other lifeforms as well -- including humans in higher concentrations. Mollusks and many aquatic invertebrates are typically particularly sensitive to copper.

Indeed. One of these days, I should try MSU's orchid fertilizer. Be interesting to see how the cps would respond.
I see, Chef, that you are a proponent of the UK spelling of "sulphur" as opposed to the Yank version, "sulfur."
