Dynamic accumulators are plants that gather macronutrients, or minerals and micronutrients, certain 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 or 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. These plants become rich in a certain substance and can then be cut down. This can be used as a fertilizer or as part of a fertilizer mix for other plants that may be deficient in those particular nutrients. The use of a nitrogen dynamic accumulator, such as a clover patch, could potentially replace nitrogen-rich fertilizers. These types of plants play an important role in many permaculture guilds. http://
