After reading this article you will learn about:- 1. Soil Moisture Constants 2. Measurement of Soil Moisture 3. Loss. Soil Moisture Constants: (i) Field capacity is the amount of moisture held by the soil after the excess gravitational water has drained away. Negative potential or free energy of soil water is 0.1 to 0.3 bars. Approximate of value is 2.54. [...]
After reading this article you will learn about the movement of water and vapour in the soil. Movement of Liquid Water: Liquid water moves in the soil under saturated and unsaturated conditions. Saturated flow of water: Soil is saturated with water which means that even the macrospores are full of water, and water at the surface of the soil possesses [...]
