Different plants accumulate different nutrients. They can bring up nitrogen, potassium, potash, calcium, sulfur, manganese, magnesium, iron, copper, zinc, silicone, and even lead.

Ones that accumulate metals like copper or zinc can also pull lead into the plant. You do not want to plant these close to old houses and eat their leaves. However, they can be used to pull lead from the soil and then disposed of to clean soil.
Strong nutrient accumulators are yarrow, chamomile, fennel, lamb’s quarter, dandelion, chicory, comfrey, geranium, and mustard. They are great to interplant with any vegetables.
If growing plants that need a great deal of nitrogen to thrive (anything with leafy growth), plant “nitrogen fixers.” Examples of these include alfalfa, beans, clover, comfrey, fennel, lamb’s quarters, lupine, peas, stinging nettles, primrose, and yarrow.
Interplant nitrogen users with nitrogen fixers and you will get thriving plants. Nitrogen users include onions, lettuce, tomatoes, squash and cucumbers.
