What Is A Dynamic Accumulator?

Based on theory or anecdotal evidence, not science, the idea is that certain plants that accumulate high concentrations of minerals in their tissue release those nutrients back into the soil when they die back on the soil surface.

Example:

Comfrey is a plant that is often given this distinction based on the belief that its long taproot mines up the minerals to the plant’s leaves. In fact, comfrey isn’t even the best hyperaccumulation plant but because of its fast regrowth, it is considered a useful dynamic accumulator.
