Summary: "Water molecules possess a certain amount of kinetic energy. The greater the concentration of water in a system, greater is its kinetic energy or water potential. If two systems containing water are in contact, movement of water molecules occur from the system with higher energy to the system with lower energy. Water potential is expressed in pascals. The value of water potential of pure water at standard temperature is 0. The water relations of climate, soil and plants have been extensively studied by scientists, but much more must be done on water conservation and on the utilisation of water by plants if the earth is to support its rapidly increasing population (diverse applications). The movement of water from the soil through the unicellular root hair and cells of epiblema upto the metaxylem of root via cells of cortex, endoderims, pericycle etc. is defined as absorption of water. Plants have two transport systems to move food, water and minerals through their roots, stems and leaves. These systems use continuous tubes called xylem and phloem, and together they are known as vascular bundles. Plants absorb water through the entire surface-roots, stems and leaves. However, mainly the water is absorbed by roots. The area of young roots where most absorption takes place is the root hair zone. The root hairs are delicate structures which get continuously replaced by new ones at an average rate of 100 millions per day. The root hairs lack cuticle and provide a large surface area. All the minerals cannot be passively absorbed by the roots as the concentration of minerals in the soil is usually low and they are present as charged particles. So, they cannot move across cell membranes. These move into the roots by using energy in the form of ATP. Besides this book will definitely provide guidelines to command area development authorities, soil engineers, teachers PG students and all those who are working in soil and water conservation field."--Back cover
