3.4: Soil Water Measurement and Movement

WebSaturated flow is water flow caused by gravity’s pull. It begins with infiltration, which is water movement into soil when rain or irrigation water is on the soil surface. When the soil profile is wetted, the movement of more water flowing through the wetted soil is termed percolation. Factors affecting movement of water include: 1. Texture . 2. WebThe fluid phase is dynamic rather than stable because its volume in soil usually varies between 0 and approximately 50% (Don Scott, 2000).Water from the atmosphere enters … WebThe movement of moisture takes place because of the difference in water potential. The portion of soil that is moist is at a low water potential, while that which is dry is at a high water potential. Moisture moves from high potential to low potential thus water rises upward in the capillary tube. Type # 3. Water Vapour Movement: breakfast sausage in the oven
