Handbook of Agricultural Geophysics

Contents Preface 1 Introduction 2 Geophysical methods to agriculture 3 Geophysical standards 4 Resistivity and electromagnetic induction 5 Conductivity 6 Magnetometry 7 Geographic information system 8 Global positioning systems IndexGeophysical methods are becoming an increasingly valuable tool for agricultural applications Agricultural geophysics investigations are commonly focused on delineating small-andor large-scale objectsfeatures within the soil profile over very large areas The book describes geophysical methods applied to agriculture might be the most important sections to some readers A few methods involve taking GPS data to better help farm machinery plant seeds apply fertilizer and harvest Emphasizing practical agricultural applications this book offers an overview of potential near-surface geophysical techniques by measuring soil conductivity using ground penetrating radarProviding background data analysis and case histories agricultural geophysics presents an idea in-depth examination of near surface geophysical methods and their agricultural applications The book includes current geophysical methods such as electromagnetic induction as well as developing methods such as geomagnetic surveying It explores the areas of agriculture that can benefit the most from these methods including precision farming and hydrologic monitoring It discusses global positioning systems and geographic conformation systems It also addresses field and laboratory techniques like time domain reflectometry cone penetrometers and gama ray tomography jacket 298 pp.…
