Dynamic accumulators are plants that are particularly effective in gathering certain plant nutrients. They may have deep tap roots that allow them to access nutrients from deeper soil levels that other plants cannot reach and draw them up to the surface, for example.
These plants can then be used as mulch, to make compost, or in organic liquid plant feed. While this is an area of permaculture practice where more research is needed, evidence is growing that the use of plants that can gather certain nutrients and store them in high concentration in a bioavailable form in their plant tissues can help maintain thriving systems.
