Re: microelements

Well, they are all important to some degree, but as you go down the scale of % of plant biomass of each micro nutrient, Mo is not needed much:) Wereas Fe is far more. This pattern extends to your question, in decreasing order, the relative importance and effects on plant health are noted in a similar manner.

Light=> CO2=> NO3/NH4 => etc on down the line. See Epstien 1972 for the mineral % break down in a common terrestrail plant. While these amounts vary plant to plant, nutriental status of said plant and submersed plants are different as well, the rough ranges of relative % ratios are not too far off.
