Aquasoil Amazonia is leonardite?

    I am starting to think that leonardite or a similar granular humate may make up a major portion of Aquasoil. Let's compare descriptions.

    Aqua Soil-

    http://www.adana.co.jp/asoil_e.htm
    ADA Aqua Soil Amazonia

    -Made from specially processed natural material from the earth.
    -Amazonia’s active ingredient, humus acid.
    -reduces pH
    -reduces hardness
    - the humus [humic] acid, promoting water plant growth has easily-soluble character, and the water could turn yellow, if the water is alkaline.
    -light weight
    -doesn't scratch glass or acrylic




    Granular Humate

    Earthgreen Products Inc.
    Huminova
    What is Humate?

    -Natural organic material mined from the ground
    -made up of
    1) humins- black, not soluble,
    2) humic acids- brown or grey, soluble at high pH (alkaline conditions),
    3) fulvic acids - yellow soluble at all pH conditions
    -reduces soil pH
    - chelates Calcium and Magnesium
    -low mineral hardness (soft), won't scratch




    The color and weight of Aquasoil seem like a perfect match to the sample of different granular humates that I have seen, as would the high cation exchange capacity. The yellow water tinge at high pH and leaching of ammonium seen with aquasoil would also be consistent with a granular humate.

    I'm guess that ADA has processed the granular humate to remove the most soluble fractions, either through treatment with a basic solution such as potassium hydroxide, or with KCl solution to remove exchangeable acids and replace them with potassium on the surface exchange sites.

    If anyone would like to try a test (since I don't currently have access to Aquasoil Amazonia),

    - Make a high pH solution by dissolving garden lime (I guess baking soda would work) try to get the pH above 10. Add some aquasoil , mix, and allow to sit for several hours. Do humic acids start leaching into the solution and turn it brown?
