RES: [compost_tea] Humic Acid



Title: Message

It is measured in a laboratory.

I have the sample sent to 2 diferent labs.

The best way to test the effectiveness I know is

run a field or green house test.

Jose: How do you measure the 50% total humic and fulvic contents?

Is there a way to measure the level of effectiveness of humic and fulvic acid?

There is a lot of snake oil when it comes to humates in general being raw,

dry extracts and/or liquid extracts.

I am doing a complete analysis of most materials available in the USA

market and will report later on.

Humisolve - USA for instance I not a honest producy  since it declares a

% that is not present in the final product. They declare 74% but it has only

50% total humic + fulvic acids.

There are various soluble humic acid products such as the ones from Humicsolve and TeraVita. I wonder if the drying process will reduce the effectiveness of the humic acid.

Liquid humic acid will work better.  I like the Hydrahume AN from Helena, the Eco-Nutrient kelp and humic acid, or the Horizon Ag humic acid.  In Australia, the Nutri-tech dry form is soluble, so it works well added to tea.

Usually dry formulations take too loong for the orgnaisms to solubilize in the tea.
  It doesn't give you growth in the tea. 

There may be dried versions of the Nutra-Tech humic acid that I don't know about in the US, so if someone finds one, let me know!
