Abstract
The first agricultural geophysics in S. Korea was vertical electrical sounding (VES) for the purpose of groundwater survey in the 1970s. After the application of VES, various geophysical approaches to solve environmental problems in rural area have been mainly applied. Moreover, according to the diversity of agricultural activities since the 1990s, various geophysical methods such as electrical resistivity (ER), electromagnetic induction (EMI), and self-potential (SP) method were extensively applied to several agricultural fields including soil characteristics with saline concentration in vast reclaimed area, costal aquifer under seawater intrusion environment, reservoir dike with leakage problem, groundwater aquifer affecting by leachate from livestock mortality burial or waste burial site, and so on. Among them, three representative geophysical techniques that have been utilized in various agricultural fields are introduced and it is essential to apply core technologies in the development of leading technologies to prepare for future agricultural environment changes. Moreover, these geophysical technologies can be applied to the fundamental technology for the precision agriculture field in the future based on the past achievements.
