i've been told with results that you want between 68-72% calcium, 15-18% magnesium, 3-5% potassium. are these correct? what is an optimum range for sodium? how do you correct an abundance or deficiency in sodium? also the extractable minors: what are some ranges to look for in these? these numbers are in the ppm. boron 0.90 iron 105 manganese 100 copper 2.52 zinc 6.05 aluminum 462 i know some test results will tell you that the soil is high or low of optimum, but my test results do not state that, plus i would like to learn to read them better anyway. thanks in advance.
