Geophysical methods are becoming an increasingly valuable tool for agricultural applications. Agricuitural geophysics investigations are commonly focused on delineating small-and/or large-scale objects/features within the soil profile over very large areas. Agricultural geophysics is an emerging discipline that involves non-invasive geophysical techniques for obtaining valuable soil surface and near surface information. The three geophysical methods predominantly used for agricultural purposes are resistivity, electromagnetic induction, and ground-penetrating radar. The sustainable management of human activities, from production to waste disposal and the cycling of finite resources, is one of the great challenges of research for the coming decades, stemming from societal needs and the growing awareness of environmental mechanisms. Geophysical techniques based on well known physical principles involve indirect measurements of earth related physical attributes and in the case of soil conductivity, contrasts resulting from soil distribution. This course is aimed at imparting practical knowledge on application of ground penetrating radar, electrical, electromagnetic and magnetic methods of exploration applied to agricultural geophysics. The book describes geophysical methods applied to agriculture might be the most important sections to some readers.
