Effectiveness of Multielectrode Earth Resistivity Method for Characterizing Putting Greens of Golf Courses

The main objective of this study is to provide evidences that near-surface geophysical methods can be useful tools for improving the maintenance and remodelling efforts of certain parts of golf courses, particularly greens. Typically, in order to determine the geometry and textural properties of soils and substrates samples should be removed from the different zone of the golf course and submitted to an accredited physical soil testing laboratory. The results from our study indicate that electrical resistivity tomography method is an efficient tool which can be used by golf course greenkeepers to assess lateral and vertical variability of soils and substrates and prevent salinity hazard from irrigation with reclaimed wastewater.The study has demonstrated that, although soil electrical resistivity depends simultaneously on many soil properties like moisture and salinity, the measurement of apparent resistivity in sandy substrates used for building putting greens can be easily correlated with his textural composition.
