Finding: Minerals
Two Swedish scientists, Dr. Nils Brundin and Dr. Sven Palmgrist, have developed a new method of detecting the presence of minerals in the soil from the analysis of trees growing in the areas. It is well known, of course, that plants absorb mineral salts indiscriminately from the soil, regardless of whether they are essential for growth or not. It is also clear that any element present in the leaves of trees and plants must have been derived from the soil. The method is intended as a pointer and would be a valuable adjunct to existing methods which include boring, magnetic and electric surveying. In all cases a bore would be necessary before the quantities in which the mineral occurred could be determined It *s said to be particularly suited to areas such as the forest regions of the tropics where it is difficult to carry out a trial bo.*e.
