The soil water holding capacity
|
Detailed explanation-1: -Increasing or decreasing the pH on either side of the pI will result in an increased water-holding capacity by creating a charge imbalance.
Detailed explanation-2: -What Influences Soil’s Water-Holding Capacity? Water-holding capacity is controlled primarily by soil texture and organic matter. Soils with smaller particles (silt and clay) have a larger surface area than those with larger sand particles, and a large surface area allows a soil to hold more water.
Detailed explanation-3: -Sandy soils contain less amount of silt so they hold less amount of water when compared to other types of soils.
Detailed explanation-4: -Soil pH affects the amount of nutrients and chemicals that are soluble in soil water, and therefore the amount of nutrients available to plants. Some nutrients are more available under acid conditions while others are more available under alkaline conditions.
