This article throws light upon the three main types of movement of water in soil. The types are: 1. Saturated Flow 2. Unsaturated Flow 3. Water Vapour Movement. Type # 1. Saturated Flow: Water moves because of water potential gradients in the soil caused mostly by gravity, salt content and water usage and the direction of flow is from a [...]
This article throws light upon the top four methods used for the measurement of soil moisture. The methods are: 1. Gravimetric Method 2. Electrical Conductivity Method 3. Measurement by using Tensiometers 4. 4. Neutron Scattering Method. 1. Gravimetric Method: This method is the classical procedure used as the check for all other methods. A soil is sampled, put into a [...]
