Development of sustainable irrigation practices will require that we understand better the biophysical processes of root-water uptake in soil, and transpiration from plant canopies. Solar energy is the driving force for most of the biophysical processes in the plant system and water movement from soil to the atmosphere. Details regarding soil, water, plant, and atmosphere (weather and climate) are described in the respective chapters. In this chapter, mostly the interactions among them are described.
