I
send samples to two different laboratories here in It
looks like Black Hearth from decent and honest products. I am not saying they are the only ones which are good, however I can testify that Humisolve is not an honest product. There
is no Humic acid as explained before in a previous
post. Humic
acid is a group of compounds ( which by the way are
neutral) which have a broad range ( from a few thousand thousands of are not soluble in water like Fulvic acidS another group with smaller molecular weight. Therefore
when you say three you must be referring to three thousand types and not only three types unless you are referring to Fulvic, Humic and
Ulmic. Then
you have three groups but Ulmic is too heavy to elicit some biological effect when sprayed in the plant. So
good Soluble Humates must have those two groups :
Fulvic and Humic acids comprising virtually thousands of deifferent molecules.
Jose, Interesting research! I
am just about to buy some humic acid and like everyone else, sure want
the best.....how do you conduct your test? Also, the best humic acid solutions
contain several different humic acids...the more the merrier, as I understand
it. Can you comment on which ones have 3 or more humic acids? Cheers, Jeff
