    • Abstract:
      The article discusses the process of phytomining, in which plants are used to extract metals from soil, focusing on the development of the technique and it's potential in environmental management and mining. Topics include the work of researchers Alan Baker and Rufus Chaney, "hyperaccumulator" plants such as alyssums that absorb high quantities of metals including nickel, and efforts to put the idea into practice to improve soils, prevent environmental damage, and extract metals.
