This book is designed to provide a complete package on different physical and chemical properties of soil along with the geological processes occurring on Earth. Both physical and chemical properties of soils are of paramount importance in affecting the crop growth. Soil texture, structure, bulk density, particle density, plasticity, consistency, adhesion and cohesion are important physical properties that play important role in affecting plant growth. Different types of acidic, saline and sodic soil, cation and anion exchange phenomena and types of soil colloids are also included in brief....

The concept of reduced or zero tillage systems is not new. Many developed and developing countries also use these systems, which are often found to generate higher yields, reduce production costs and reduce erosion and other forms of land degradation, with corresponding benefits for the natural resource. A whole system of mechanization has been developed in these countries to ensure good crop establishment, proper placement of fertilizer and handling of crop residues for better yield. These equipments are accompanied by a set of recommended crop management and protection for handling weed,...
