This article throws light upon the two processes by which water is lost from soil. The processes are: 1. Percolation Losses 2. Evapotranspiration. Process # 1. Percolation: The losses of soil water through percolation are maximum under humid climate where precipitation is high. Different essential plant nutrients are lost from soils through such percolating water. Percolation losses of water can [...]
After reading this article you will learn about the calculation of soil moisture. The soil moisture calculations in percentages on a weight basis have been commonly used, but this does not give a true picture of soil-moisture relationships. Two soils may have similar moisture content on a weight basis but not on a volume basis. Calculations on a volume basis [...]
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 [...]
