I am applying magnesium sulfate monohydrate ( ESTA Kieserite, with 25% Mg and 50 SO3). The pH of the soil is 7.2. My lab does not measure the EC value. I could measure it by myself, What does it tell me if the EC value goes up? Yes, I am stuck with the high Calcium base saturation…..
We have a lot of rain, 1100mm annually, so nutrients are washed out.
