Hi,

I wonder if you have tried Leonardite in container mix?

There is a product called PerlHumus by Humintech;

I wonder if it may help citrus in containers.

Best,

I have never tried it for growing plants, but I did my dissertation on the effects of humic acid on some organisms in the marine environment. I can attest to its ability to bind many elements --like a chelator. It had positive effects on the organisms I studied.

By definition humic acid is the organic matter in soil that can be extracted with base (>pH 10) and then precipitated by acid (pH 4.5), fulvic acid is the material extracted by base but soluble in acid. At the pH of citrus soil (6-7) all of the fulvic acid will be soluble and some of the humic will be and will therfore just wash out of your container.

There is a lot of this type of ingredient mined in southern Utah. I currently have 5-gallons of Utah fulvic acid in stock. I experimented with it over the past 4 or 5 years. I also read Dr. Jackson's 750 page book dealing with humic and fulvic acids. As a side note, fulvic acid does help relieve the pain of burns. I know people who actually drink fulvic acid as a chelator. My results did not offer enough positive results, and were discontinued. - Millet

Ok, thanks for the info.
