The application of geophysical detection techniques to mapping the underground of agricultural and forest fields has accelerated in recent years. Geophysical imaging provides an alternative or complement to traditional methods of collecting subsurface variables over time and space. Where previously the standard was soil sampling and laboratory analysis to assess the condition of a soil for its various purposes, in situ detection techniques are proving to be a very effective way to assess variation in soil / underground properties. This work is a review of the state of the art related to the most applied geophysical techniques in the detection of underground components and processes that can influence the productivity and functioning of forest ecosystems and agricultural systems. This review highlights the opportunities, applications and challenges presented by geophysical images (radargrams and tomograms) in the multidisciplinary fields of Biogeosciences. Both geophysical research techniques are very attractive to the scientific community, allowing the underground to be accurately mapped, plot rooting, monitor water content, identify sales movement and agrochemicals. Agronomists, foresters, and the scientific community would benefit from adopting these minimally invasive, scalable imaging technologies to the underground and advance our collective research.
