CONSIDERATIONS ON CONTACTLESS ELECTROMAGNETIC TECHNIQUES FOR MEASURING SOIL CONDUCTIVITY
Tudor BURLAN-ROTAR, Constantin STANESCU, Melania TAMAS
Conventional determination of resistivity by galvanic method requires a relatively large amount of labor to apply them in practice and is therefore expensive. It is the lateral or vertical variations of resistivity which form the basis of any interpretation. …
