    I just got my soil test results back and my base saturations are K 2.3, Ca 92, Mg 6. How do I raise my Mg and Lower my Ca?

    adding mg will lower your calicium, around here its usually the opposite, so I am always adding calcium to lower mg

    Agreed JD...It would have been nice to see a sulfur level on his soil test (another thread).

    There are all sorts of trace element materials, both granular and liquid, you may apply in accordance with your soil test results.
    However, prior to undertaking this type of application you must first have a thorough understanding of what your soil's CEC is as well as the hydraulic conductivity as both of these readings are necessary to understand both frequency of the application as well as the amounts applied.
