Method And System To Facilitate Deep Phytoremediation
US Patent:

Filed:
Mar 29, 1999
Appl. No.:
09/282012

Abstract:
A method and system to facilitate deep phytoremediation by planting a tree deeper than is traditionally done and then supplying at such depths the air; water; nutrients; and, optionally, the gaseous exchange needed for the development of root systems. Either forced air or the germination and growth of mycorrhizae spores not creates, in compacted soil, macro pores through which root hair can pass. The trunk of the tree can optionally be coated with either vitamin B1 or mycorrhizae spores or a combination of these substances to encourage root growth even further. To prevent water from flowing to the bottom of the hole in which the tree has been planted and air from flowing to the top of such hole, clay layers are optionally used to separate different areas where root growth is desired. Conversely, to preclude root growth in areas where such growth is not desired, either the trunk of the tree is wrapped, in such areas, with a material that is impervious to roots or such areas are backfilled with gravel.
