Jeff;

Yes. True I think partially. I don't want to cross swords with you on this
because you knowledge probably is a multiple of mine in this area.

It is quite common though to supply calcium, and potash and nitrogen to a
plant in this fashion. Its difficult to get P into a plant through the soil
as its tied up quickly. Its also common to use EDTA or fulvic to cross the
epidermal layer while using oils and soaps to cut the surface tension of
water droplets and dissolve the wax layer on many plant surfaces. Humic does
not seem as effective due to its large molecular size.

As an aside. If you don't have enough calcium in your soil, your plant will
be short of all nutrients - macro and micro. Zimmer coined the phrase "the
trucker of all miners" when talking about calcium. At least I think it was
he. Albrecht of course is remembered by many as the guy who worked with
calcium.

There are many essential nutrients that can get into the leaf. Many are not
mobile in the plant, however. It is impossible to supply the macronutrients
via foliar feeding in sufficient quantities according to everything I have
read. Iron, possible. Most other stuff, no IMHO

Teaming with microbes,
