FYI A note from a friend that has a big green house ES when used with care and in the proper amounts can supply magnesium and in so doing, increase the uptake of calcium, so if your soil is magnesium deficient, it can be of benefit. But the blanket and repeated application of it by so many without knowing first of a deficiency and without regard for it's side-effects and proper amounts can cause many different problems including killing the plants. I know that I will hear from it's devotees on this but having just gotten home from making 2 house calls on greenhouse clients who, between the 2 of them, managed to kill some 80 tomato plants and 12 pepper plants by adding varying amounts of ES (one added 1/2 cup and the other 1/2 cup of ES and 1/2 cup of bone meal) to each planting holes - I'm currently on my soapbox so please bear with me! Both argued that "they had 'heard' how good it was and so if a little was good, alot was even better". Can you imagine the amount of salt that put in each of those planting holes?! And then they wonder why all their plants died. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Byron
