What are these? (in reference to aquatic plants)
Now, that may sound like an easy question, but I assure you the answer will not be an easy one.
I have spent the better half of the night researching this very question and still have not answered it fully. (that's what you get when you have paid sick time, LOL)
OK, let me begin with what I am talking about. I was researching plant deficiencies and one of them was sulfur, but I did not know S was either a Macro or a Micro Nutrient for a plant, and that is what started the search. Upon researching this, many different resources list different Macronutrients and Micronutrients for aquatic plants.
You see listed on AA the standard N,P,K and just "micro's" all the time. I have NEVER seen S mentioned here as referenced as a micro or macro Nutrient. (ok LWB mentioned it once.search is your friend)
A lot of sites list N, P, K, C, S, Mg, and Ca as the Macro's and Fe, Mn, Mg, Zn, Cu, Mo, and B as the Micro's.
I would only have to assume that some plants need some macro's more then others, but wouldn't you want the full marco's in your tank regardless? We as AA members do not know what species of plants are going into other peoples tanks right? or is it because S is always available in my tank already? like Ca++ and Mg++. I dose K2SO4, so I have S available, but what if I didn't?
(for the heavy guys/gals what makes each one of these a macro/micro and for which species of plant? and for which part of the plant? maybe all 4 volumes of the AGA guides would help.(yes, it really has been that long of a night))

EDIT: I do see that my root tabs contain 12% sulfur.
