Elements of Soil Science

About this book

This work covers instrumentation and techniques providing 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 states that characterization of physio-chemical properties of soil gives information of 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. Also, a computer programme package is included for crop simulation of soil hydraulic processes and use of simulation models for crop growth, root zone soil moisture and evapotranspiration.
