This book covers instrumentation and techniques for use of dielectric probes, inductive electromagnetic meter, multi-angle Radarsat SAR data, total information content index based on optical remote sensing and isotopes, and radiation techniques in soil moisture studies. It also discusses the characterization of physio-chemical properties of soils, charge characteristics of arid soils, electrochemical properties, soil water relations, properties of black clay soils, diagnosis and remedial measures of salt affected lands, and intensive agriculture induced changes in soil properties. Providing information on the frontiers of basic and applied sciences on the use of the emerging technologies of remote sensing, GIS and modeling of soil physical parameters, this book will be useful to all researchers working in the field of soil science.
