Natural soil regeneration on such a hostile site could take up to 60 years. By using these specific worm varieties, the project aims to complete the process in just . Alongside the worms, around 250,000 trees, including willow and alder, have been planted. These trees perform a dual role: their roots extract remaining contaminants, and they can eventually be harvested for wood burning or manufacturing. Project Partners This rescue plan was developed by a collaboration between: HL Banks : A local landscaping and earthmoving company. Scottish Greenbelt : A regional developer.
Earthworm casts are significantly richer in plant-available nutrients than the surrounding soil.
While worms do not destroy heavy metals, their activity stimulates microbial growth. These microbes help bind or transform toxins into less bioavailable forms. Detailed Answer Explanations Why Question 1 is Paragraph E worms put new life into derelict site reading answers
