Sorry this is a little of subject, I am new to this subject of hugelkultur raised beds, but I read on blog about so much wood being used that it would create so much available potash that it would cause the plants growing in it to be deficient in other necessary nutrients because they would just absorb the potassium, is this true and if so would soil amendments on the surface of the heap make the roots of the plants absorb more of the other nutrients and not just potassium at the lower levels of the soil where all the wood is ? The point to my question is the actual nutritional value of the fruit/ vegetable if only potash is the abundant element !
