This article throws light upon the three ways by which water is retained in the soil. The ways are: 1. Cohesion and Adhesion Forces 2. Surface Tension 3. Polarity or Dipole Character. Way # 1. Cohesion and Adhesion Forces: These two basic forces are responsible for water retention in the soil. One is the attraction of molecules for each other [...]
After reading this article you will learn about the physical and biological classification of soil water. Physical Classification of Soil Water: From a physical point of view the terms gravitational, capillary and hygroscopic waters are identified. The forms of soil moisture are: 1. Gravitational Water: Gravitational water occupies the larger soil pores (macro pores) and moves down readily under the [...]
After reading this article you will learn about the potential and importance of soil water. Potential of Soil Water: The retention and movement of water in soils, its uptake and translocation in plants and its loss to the atmosphere are all energy-related phenomena. The more strongly water is held in the soil, the greater is the heat (energy) required. In [...]
