Researchers in Australia have discovered that it is possible to detect underground gold deposits by analysing the leaves of trees that are growing above. It is thought that Eucalyptus trees may translocate gold from mineral deposits below, leaving tiny deposits in their foliage.
Tests are conducted using a process called biogeochemistry.
Although gold has been previously measured in plant samples, there has been doubt as to whether it was truly absorbed, via the plant’s roots, rather than merely adsorbed on the plant surface as airbourne contamination.
This latest research appears to confirm that the gold contained within a tree’s leaves has, in fact, been drawn up through the plant’s roots.
Even though the actually quantity found within a single tree may be small, the evidence of gold being present suggests that below ground deposits are much larger.
After starting my garden maintenance and landscaping business in 1984 and running it for 21 years I decided I needed a change of direction (probably a mid life crisis, no seriously! :-0) Together with my family, wife Donna, Son Henry and Daughter Fleur (not forgetting Hector the Black Labrador) I moved to France in search of an old farmhouse to renovate. In the interim period whilst waiting for the contract to go through I started writing a blog. Initially just to keep a diary for family and friends to keep up with our progress if they wished but then it occurred to me that there isn’t a real time watcher of the landscape industry in the UK. I didn’t want to waste my experience and experiences so I decided I could put all of this Juice to good use so I started Landscape Juice.
