So... would a dynamic accumulator plant grown in poor (from a mineral perspective) soil still have a relatively high concentration of the minerals that were present?
For example, would a comfrey plant grown in the poor soil mentioned above be similar or much lower in absolute mineral content than a comfrey plant that was grown in soil that had a more balanced/rich soil?
Will a plant that tends to accumulate high levels of say, calcium, grow well in a soil that is low, has trace levels or is entirely lacking in calcium?
I've come across numerous references stating that soil west of the Cascades tends to be low in a number of minerals such as calcium and sulfur. I then wonder where the animals, insects and plants that live here (and seem to thrive) find sources of these minerals?
