Dynamic accumulators are plants that gather certain
micronutrients,
macronutrients, or minerals and store them in their leaves. These plants can be used either for detoxifying soil or for gathering a certain nutrient or mineral from an area. For instance,
clovers will mine great quantities of
nitrogen out of the air via a symbiotic relationship with bacteria. These bacteria convert gaseous nitrogen into a form available to the clover, and exchange this nitrogen for exudates/sugars given by the clover. When the clover dies or is cut down, the green matter breaks down and releases the nitrogen into the soil.
